To solve 1/8x = -5 , you will need to multiply both sides of the equation by 8. once you do that you will get the answer:
x= -40
let me know if you have any other questions

1/8x = -5

isolate the x, remember that what you do to one side, you do to the other (because of equal sign)
1/8x(8) = -5(8)

x = -5(8)

x = -40

<u>Note:</u> two positive numbers multiplied or divided = positive answer. One negative and one positive number multiplied or divided = negative answer. Two negative numbers multiplied or divided = positive answer

hope this helps

A summer camp is organizing a hike and needs to buy granola bars for the campers. The granola bars come in small boxes and large

Irina18 [472]

Answer:

The Answer is: There are 8 small boxes and 9 large boxes. See explanation below for variables and variable definitions.

Step-by-step explanation:

Let s = small boxes. Let b = large boxes.

s + b = 17

You can solve for s:

s = 17 - b

You can solve for b:

b = 17 - s

10 times the number of small boxes plus 24 times the number of large boxes is equal to 296 granola bars.

10s + 24b = 296

Substitute:

10(17 - b) + 24b = 296

170 - 10b + 24b = 296

14b = 296 - 170

14b = 126

b = 126 / 14 = 9 large boxes

Find the number of small boxes, s:

s = 17 - b = 17 - 9 = 8 small boxes

There are 8 small boxes and 9 large boxes.

Proof:

10(8) + 24(9) = 296

80 + 216 = 296

296 = 296

Write an equation for a direct variation that includes the point (3, 18)

erma4kov [3.2K]

Direct variation means that the line goes through the origin of the graph, so you know that the line must go through point (0,0). Using that along with the given point, you can find the slope of the line.

m = $\frac{y_2 - y_1}{x_2 - x_1}$
m = $\frac{18 - 0}{3 - 0}$
m = $\frac{18}{3}$
m = 6

Now that you know the slope of the line you are looking for is 6, you can plug that into a point-slope form equation and find the equation of your line.

y - y_1 = m (x - x_1) Plug in either set of coordinate. I chose (3, 18).
y - 18 = 6 (x - 3) Use he Distributive Property
y - 18 = 6x - 18 Add 18 to both sides
y = 6x

The equation of a direct variation line that includes the point (3, 18) is y = 6x.

Carmen simplifies the expression (4 y 8 x 6) 25 (4 x 6 y 7). The coefficient of the variable y in her simplified answer is 4. 6.

Sever21 [200]

Carmen simplifies the expression and gets the coefficient of y is 10. Thus, the correct option is C.

<h3>What is simplification?</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

Carmen simplifies the expression $\rm (4 y + 8 x + 6) + 25 + (4 x +6 y +7)$ .

We can add x term with x, y term with y, and constant with constant.

On simplifying, we have

$\rm (4 y + 8 x + 6) + 25 + (4 x +6 y +7)\\\\12x + 10y + 38$

Thus, the coefficeint of y is 10.
