Answer:
Yes 4/=8/6 are proportional
If you look at the first fraction 4/3 and multiply 2 by the denomenator and numerator it will equal to 8/6 . Now to switch it up 8/6 divided by 2 is 4/3 so yes the t2 fraction are proportional.

Answer:
40, 80, 120
Step-by-step explanation:
0, 40, 80, 120, 160, 200
+40
Answer:
0, 40, 80, 120, 160, 200
Step-by-step explanation:
The numbers are decreasing by 40. 200-160=40. Therefore, we need to subtract 40 each time from every number we get.
160-40=120
120-40=80
80-40=40
Now, plug the numbers into the sequence. It should now look like this:
0, 40, 80, 120, 160, 200

(2x+y,x+3y)=(12,11)
Answer:
x=5, y=2
Step-by-step explanation:
Use the information given:
2x+y=12x+3y=11Subtract them because we have two variables and two equations:
2x+y=12
- x+3y=11
–––––––––
x-2y=1
We can by 1+2y (Add 2y to both sides) instead of x:
2(1+2y)+y=122+4y+y=122+5y=125y=10y=2(1+2y)+3y=111+2y+3y=111+5y=115y=10y=2Now we can figure out x as we know y:
2x+1(2)=122x+2=122x=10x=5x+3(2)=11x+6=11x=5(y - 6) = -4(x + 3) in slope intercept form
Answer:
y=-4x-6
Step-by-step explanation:
use the formula y=mx+b
oh btw i just posted a question so please maybe help with it???
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]y - 6 = - 4(x + 3)[/tex]
[tex]y - 6 = - 4x - 12[/tex]
Add sides 6
[tex]y - 6 + 6 = - 4x - 12 + 6[/tex]
[tex]y = - 4x - 6[/tex]
This is the slope-intercept form.
Done...

Mrs. Coughlin bought 2.25 pounds of turkey at $4.96 per pound and 0.75 pound of provolone cheese at $5.20 per pound. If Mrs. Coughlin gave the cashier $20, how much change will she receive?
Answer:
$4.94
Step-by-step explanation:
To find out the change from $20, we need to find her total cost.
Total cost = 2.25lbs * $4.96/lb + 0.75lbs * $5.20/lb
Total cost = $11.16 + $3.90 = $15.06
Now $20 - total cost = $20 - $15.06 = $4.94

please answer the question it shows what I got wrong so don’t choose that one
Answer:
e. the triangles are congruent
Step-by-step explanation:
Similar means they're alike but are not the same, congruent means they're the same. The triangles are the same so therefore they're congruent.
Also it's congruent because u see the triangles on the bottom and top line? It means that the lines are parallel. So the lines at the side have to be the same length and tilt in an equal way so the top and bottom lines can be parallel

a) 4865
(Nearest ten)
Answer:
irst, 4865 rounded to the nearest ten is:
4870
Step-by-step explanation:
Here we will tell you what 4865 is rounded to the nearest ten and also show you what rules we used to get to the answer.
Remember, we did not necessarily round up or down, but to the ten that is nearest to 4865.
When rounding to the nearest ten, like we did with 4865 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

The volume of a solid cube is 1700m3.
Work out the surface area.
Give your answer rounded to 1 DP.
Answer:
849.7m2
Step-by-step explanation:
L= length
SA = surface area
volume = L x L x L
1700= L x L x L
find cube root
=11.93m
round off to 1 dp
=11.9m
SA= 6( L x L)
= 6( 11.9 x 11.9)
=6(141.61)
=849.66m2
round off to 1 dp
=849.7m2

Find the volume of the solid. *
7)
Answer:
B
Step-by-step explanation:
The volume (V) is calculated as
V = area of triangular face × depth
Area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 3 and h = 4 , then
A = [tex]\frac{1}{2}[/tex] × 3 × 4 = 6 Km²
Now depth = 2, thus
V = 6 × 2 = 12 Km³ → B
∠A and \angle B∠B are vertical angles. If m\angle A=(3x+26)^{\circ}∠A=(3x+26) ∘ and m\angle B=(x+20)^{\circ}∠B=(x+20) ∘ , then find the value of x.
Answer:
The value of x is -3
Step-by-step explanation:
The vertical angles are equal in measures∵ ∠A and ∠B are vertical angles
→ By using the rule above
∴ m∠A = m∠B
∵ m∠A = (3x + 26)°
∵ m∠B = (x + 20)°
→ Equate their measures
∴ 3x + 26 = x + 20
→ Subtract x from both sides
∵ 3x - x + 26 = x - x + 20
∴ 2x + 26 = 20
→ Subtract 26 from both sides
∵ 2x + 26 - 26 = 20 - 26
∴ 2x = -6
→ Divide both sides by 2
∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{-6}{2}[/tex]
∴ x = -3
∴ The value of x is -3

Eva bought 9 hanging baskets and 9 Petunias for her flower garden. Each hanging basket cost $5.48 and each Petunia cost $18.50. Eva has $250 to spend on items for her garden. How much money will Eva have left after her purchases?
Answer: Eva has left $ 34.18 after her purchases .
Step-by-step explanation:
Given: Each hanging basket cost $5.48
Cost of 9 hanging basket = 9 x $5.48 = $ 49.32
Each Petunia cost $18.50.
Cost of 9 Petunias = 9 x $18.50
= $ 166.5
Eva has $250 to spend on items for her garden.
Money left = $(250 -(49.32+166.5))
= $ (250 -215.82)
= $ 34.18
Hence, Eva has left $ 34.18 after her purchases .

Ms. Hogan paid $13.25 for 5 tacos and 1 soda. The price of a taco is $2.50. What is the price of the soda?
Answer: $0.75
Step-by-step explanation:
To solve this problem, we can create 2 equations. Let's use x for tacos and y for soda.
Equation 1: 5x+y=13.25
Equation 2: x=2.5
Since we know the value of x, we can plug it into Equation 1 to solve for y.
5(2.5)+y=13.25 [multiply]
12.5+y=13.25 [subtract both sides by 12.5]
y=0.75
Now, we know the price of the soda is $0.75.
Answer:
The soda costs $0.75.
Step-by-step explanation:
We are given that Ms. Hogan paid $13.25 for 5 tacos and one soda. We are also given that one taco costs $2.50. Therefore, we can set up a system of equations to solve for how much a soda costs.
[tex]\displaystyle\left \{ {{5x + y = \$13.25} \atop {x = 2.50}} \right.[/tex]
This is our required system of equations. We are given that one taco costs $2.50, so this is our x. Therefore, the price of one soda is y.
We can use the second equation and substitute it in place of the x in the first equation to solve for the price of the soda.
[tex]\displaystyle5x+y=\$13.25\\\\5(2.50)+y=\$13.25\\\\12.5 + y = \$13.25\\\\y = \$0.75[/tex]
Therefore, one soda costs $0.75.

Answer:kenny didnt find the real factor next to y and x and he swerved past the axis
Step-by-step explanation:
Solve the following equation for x. x = -2 x = 2 x = -17 x = -7 (x - 5)/2 = -6
Step-by-step explanation:
x= -2,
(x - 5) / 2= -6
( (-2) - 5) / 2= -6
(-7) / 2 = -6
-3.5 = - 6
right hand side not equal to left hand side of this equation.so,x= -2 cannot exist for this equation.
x=2,
(x - 5) / 2= -6
(2 - 5) / 2= -6
(-3) / 2= -6
-1.5 = - 6
right hand side not equal to left hand side of this equation.so,x= 2 cannot exist for this equation.
x= -17
(x - 5) / 2= -6
( ( -17) - 5) / 2= -6
(- 22) / 2= -6
-11 = -6
right hand side not equal to left hand side of this equation.so,x= -17 cannot exist for this equation.
x= -7,
(x - 5) / 2= -6
( ( -7) -5) / 2= -6
(-12) / 2= -6
-6= -6
right hand side equal to left hand side of this equation.so,x= -7 exist for this equation.

Someone please answer its due by midnight
Answer:
Look below :)
Step-by-step explanation:
1. coefficient
2. constant (it's referred to as a constant because the value never changes)
3. This polynomial has 4 terms. We know this by counting them. 5x^3 is one term, -x^2 is the second term, 5x is the third term, and -8 is the fourth term.
4. In descending order: 2, 1, 3, 4. The degree is the same value as the exponent. For the last term, x^2y^2, you add the values of the exponents together to get the degree.
5. -2 is the coefficient. The term with the third degree, or has 3 as the exponent, is -2x^3.
6. 1 is the coefficient. The term with the second degree is x^2. When the coefficient is 1, usually the 1 isn't written because any number multiplied by 1 equals that number (x * 1 = x)
7. 5 is the degree of the polynomial. To find the degree of a polynomial, find whichever term has the highest value for an exponent. In this case, 5 is the highest exponent.
8. 2 is the degree of this polynomial. Although none of the terms may look like they have a degree of 2, in order to find the actual degree of 4xy you have to add the values of the degree of x and y to find the actual degree. If x and y both have a degree of 1, you add those together to make 2.
9. 2[tex]x^{3}[/tex] - 7[tex]x^{2}[/tex] + 5x - 15. To order a polynomial from highest to lowest you have to order the terms in decreasing value of their exponents.
10. -4[tex]x^{3} y[/tex] + 2xy + 5x + 7.
I hope this helps :)
