Answer:

( c ) x = 2.5

Step-by-step explanation:

3(17x - 6.5) = 108

divide both side of the equation by 3...

17x - 6.5 = 36

17x = 36 + 6.5

17x =  42.5

x = 2.5

hence the value of x is 2.5...

Answer is 2.5
…….

3(17x-6.5) = 108 distribute the numbers in parentheses

51x -19.5 = 108.. add 19.5 to both sides

51x = 127.5

Divide both sides by 51
X = 2.5 is the answer

Write the equation of the line that passes through the point (-2, 4) and has a slope of -1. Show work please
vovangra [49]

Answer:

y = -x + 2

Step-by-step explanation:

If you know the slope and a point on the line, then you can find the equation with an equation:

(y - y1) = m (x - x1)

We have our slope, -1; we have a x1, -2, and a y1, 4, so we're all set to find the equation. Plug in the numbers:

y - 4 = -1 ( x + 2 )

y - 4 = -x - 2

y = -x + 2

Our equation is y = -x + 2

PLEASE HELP ME I WILL GIVE BRAINLIEST
Leokris [45]

Answer:

there are fourteen 4-point questions and twenty six 2-point questions.

Step-by-step explanation:

Given : A 40-question test has 108 possible points.

There are m 4-point questions and n 2-point questions.

So , equation for total number of questions in the test :

m + n = 40 | 4n + 2n = 108

Multiplying (i) by 2 , we get

2m + 2n = 80

Subtract (iii) from (ii) , we get

2m = 28

⇒ m = 28/ 2 = 14

Using value of m in (i) , we get

14 + n = 40 ⇒ n = 26

from this we get there are fourteen  4-point questions and twenty six 2-point questions.

hope this helped!

A rectangular prism has a width of 3 inches, and height of 4 inches, and a width of 5 inches. if the height is is doubled, what
Elan Coil [88]

Answer:

The volume doubles to 120

Step-by-step explanation:

Volume of Rectangular Prism Formula: V = lwh

Step 1: Find volume of given lengths

V = 3(4)(5) = 60 in²

Step 2: Find volume when we double <em>h</em>

4(2) = 8

V = 3(8)(5) = 120 in²

Step 3: Divide the 2 numbers to find the ratio

120/60 = 2, or double the amount.
