Answer:
5
Step-by-step explanation:
Let :
x(1) be 2
y(1) be 5
x(2) be -2
y(2) be 2
We know that distance between any 2 points is equal to:-
[tex] \sqrt{{(x(2) - x(1) )}^{2} + ({y(2) - y(1))}^{2} } [/tex]
So using the above formula ,
[tex] \sqrt{ {( - 2 - 2)}^{2} + {(2 - 5)}^{2} } [/tex]
[tex] = > \sqrt{ {( - 4)}^{2} + {( - 3)}^{2} } [/tex]
[tex] = > \sqrt{16 + 9} [/tex]
[tex] = > \sqrt{25} = 5[/tex]

There are 5 green jelly beans, 7 red jelly beans and 8 yellow jelly beans. What percent of the jelly beans are red?
Answer: 35%
Step-by-step explanation:
8 + 5 + 7 = 20
50% = 10
25% = 5
10% = 2
5% = 1
25% + 10% = 5+2
35% = 7

Point T is on line segment SU. Given ST = 2x + 6, TU = 4, and SU = 4x, determine the numerical length of ST
Step-by-step explanation:
Point T is between Points S and U, where all 3 points are collinear.
Therefore ST + TU must be equal to SU.
(2x + 6) + 4 = 4x
2x + 10 = 4x
2x = 10
x = 5.
Hence, length of ST = 2(5) + 6 = 16.
The length of ST will be 16 units.
What is a line segment ?A line segment is basically a line with two end points.
two or more than two co-linear points is needed to form a line segment.
In the given question
Line segment is SU
Point T is in between point S and point U here all the points are co-linear
SU = ST + TU
4x = (2x + 6) + 4
4x = 2x + 10
2x = 10
x = 5
∴ The length of ST = 2x + 6 = (2×5) + 6 = 16 units

What is the solution to 4x-8=12 please explain.
Answer:
x=5
Step-by-step explanation:
4x−8=12
Step 1: Add 8 to both sides.
4x−8+8=12+8
4x=20
Step 2: Divide both sides by 4.
4x
4
=
20
4
x=5
Answer:
One solution, x=5.
Step-by-step explanation:
4x-8=12
To find the solution we have to find the value of x.
to find the value of x, we have to add 8 to BOTH sides.
4x-8=12 (Why add 8? because we have to do the opposite of the sign!)
+8 +8
4x=20
Now to find X we have to ISOLATE IT.
So we take out 4, How? We do the opposite to both sides.
4/4 Cancels out
20/4 = 5
So now we know X=5
Insert in the main problem to check.
4(5)-8=12
20-8=12
12=12

Write a paragraph proving that x=8 in the equation 7x-28=28
Answer:
[see below]
Step-by-step explanation:
We would need to undo the equation and preform inverse operations to get 'x' on one side. First, we need to get rid of 28 by adding 28 to each side. This would leave us with 7x on one side. Then, we wound divide each side by 7. This would leave us with 'x = 8'. If we plugged in the value, then it would satisfy the equation.
[tex]7x-28=28\\\\7x-28+28=28+28\\\\7x=56\\\\\frac{7x=56}{7}\\\\ \boxed{x=8}[/tex]
Checking the answer:
[tex]7(8)-28=28\\\\56-28=28\\\\\boxed{28=28}[/tex]

What is the value of x in the equation 3x-4y=65, when y=4?
x=134
O x=21 / 3
O x=23
X=27
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed { \sf{x = 27}}}}}[/tex]
Step-by-step explanation:
Given, value of y = 4
To find : Value of x
[tex] \sf{3x - 4y = 65}[/tex]
plug the value of y
[tex] \dashrightarrow{ \sf{3x - 4 \times 4 = 65}}[/tex]
Multiply the numbers : 4 and 4
[tex] \dashrightarrow{ \sf{3x - 16 = 65}}[/tex]
Move 16 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{3x = 65 + 16}}[/tex]
Add the numbers : 65 and 16
[tex] \dashrightarrow{ \sf{3x = 81}}[/tex]
Divide both sides by 3
[tex] \dashrightarrow{ \sf{ \frac{3x}{3} = \frac{81}{3} }}[/tex]
Calculate
[tex] \dashrightarrow{ \sf{ x = 27}}[/tex]
Hope I helped!
Best regards! :D
Answer:
Step-by-step explanation:
-4 x 4=-16 so you add the 16 to the 65 and get 81 so then you divide the 3 from the x so it would be 81/3=27
What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15? 4 8 80 200
Answer:
x = 200
Step-by-step explanation:
Given
[tex]\frac{1}{5}[/tex] x - [tex]\frac{2}{3}[/tex] y = 30 ← substitute y = 15 into the equation
[tex]\frac{1}{5}[/tex] x - [tex]\frac{2}{3}[/tex] × 15 = 30 , that is
[tex]\frac{1}{5}[/tex] x - 10 = 30 ( add 10 to both sides )
[tex]\frac{1}{5}[/tex] x = 40 ( multiply both sides by 5 to clear the fraction )
x = 200
The value of x is 200.
Here, given expression is
one-fifthx – two-thirdsy = 30,
We have to find the value of x when y = 15.
What is Mathematical expression?
Mathematical expression is a way where calculations and analytical processes should be observed.
Now, given expression is
⇒ one-fifthx – two-thirdsy = 30,
⇒ [tex]\frac{1}{5} x - \frac{2}{3} y = 30\\[/tex]
When y = 15
⇒ [tex]\frac{1}{5} x - \frac{2}{3} *15 = 30\\\\\frac{1}{5} x -2* 5 = 30\\\\\frac{1}{5} x = 30 + 10\\\\\frac{1}{5} x = 40\\\\x = 200[/tex]
Hence, The value of x is 200.

Seventeen members of Tim's family are going to an amusement park during the week of their family reunion. Adult tickets cost $34 each and child tickets cost $31.50 each. If the total cost for admission to the part is $558, how many adults went to the park? a 7 b 8 c 9 d 10
Answer:
c.
Step-by-step explanation:
Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.
We have $34x + $31.5(17 - x) = $558.
$34x + $31.5(17 - x) = $558
$34x + $535.5 - $31.5x = $558
$2.5x = $22.5
x = 9
Hence the answer is c.

a bus is traveling at a constant speed. if the bus travels 15 1/2 miles in 1/3 of an hour how many miles will the bus travel in one hour?
Answer:
46 1/2 miles
Step-by-step explanation:
Given:
Distance = 15 1/2 miles
Time = 1/3 hour
Distance =?
Time = 1 hour
Distance : time
15 1/2 miles : 1/3 hour = ? miles : 1 hour
31/2 miles ÷ 1/3 bout = x miles / 1 hour
31/2 × 3/1 = x / 1
93 /2 = x
x = 93/2 miles
= 46 1/2 miles
Therefore, the bus will travel 46 1/2 miles in an hour
Evaluate the expression, given functions f and h: f(x) = 3x − 2, h(x) = −2x2 + 3x − 6. f(7/3) - h(-2)
Answer:
The answer is 25Step-by-step explanation:
f(x) = 3x - 2
h(x) = - 2x² + 3x - 6
First to find f(7/3) substitute the value of x that's 7/3 into f (x)
That's
[tex]f( \frac{7}{3} ) = 3( \frac{7}{3} ) - 2 \\ = 7 - 2 \\ \\ f( \frac{7}{3} ) = 5 \: \ \: \: \: \: \: \: \: \: \: \: \: [/tex]To find h(-2) substitute the value of x that's - 2 into h(x)
We have

Solve step by step 3(2x-4)=8
Answer:
x = 3.33... or 10/3
Step-by-step explanation:
3(2x - 4) = 8
distribute the 3 into the parentheses
3 • 2x = 6x
3 • -4 = -12
6x - 12 = 8
add 12 to both sides
6x = 20
divide both sides by 6
x = 3.33... or 10/3
Answer: x = 10/3
Step-by-step explanation:
3(2x-4) = 8 apply the distributive property on the left side
6x - 12= 8 Add 12 to both sides
+12 +12
6x = 20 Divide both sides by 6
x= 20/6 which simplifies to 10/3
