Answer:

i would say 18/24

Step-by-step explanation:

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 :)

Answer:  27:18 and 13:x can also be written as 27/18 and 13/x

therefore, 27:18 = 13:x

                 27/18 = 13/x

                 27/18 *13= x

               x = 19.5

Answer:

The value of x is -3

Step-by-step explanation:

∵ ∠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

[tex]x = - 10 \\ [/tex]

[tex]x = 2[/tex]

Step-by-step explanation:

[tex] \sqrt{20 - 8x} = \times [/tex]

[tex]20 - 8x = {x}^{2} [/tex]

[tex] {x}^{2} + 8x - 20 = 0[/tex]

[tex]x = - 10[/tex]

[tex]x = 2[/tex]

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

Answer:

f=7

Step-by-step explanation:

1. distribute 4 too .5 and .25

2. subtract the f from each side

3.combine like terms

this leaves you with f=6+1 which is 7

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.

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

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

Answer:

x=5, y=2

Step-by-step explanation:

Use the information given:

Subtract 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:

Now we can figure out x as we know y:

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: 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 .

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

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.

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

Answer:

5 5/7

Step-by-step explanation:

-4*6/7*-5/3

We can multiply the numerators

-4 * 6*-5 = 120

We can multiply the denominators

7*3 =21

Put the numerator over the denominator

120/21

The top and bottom are both divisible by 3

120/3 = 40

21/3 =7

The new improper fraction is 40 /7

Changing from an improper fraction to a mixed number

7 goes into 40 5 times with 5 left over

5 5/7
