The amount of paper that the copy shop used this month was a 25% increase of the amount of paper they used last month. This month, there were 78 copies made. How many copies were made last month?

Answers

Sorry forgot to post the problem here it is

Answers

Answer:

55

Step-by-step explanation:

m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50

You subtract x, leaving it to be 2x + 40 = 50

Subtract the 40, leaving it be 2x = 10

Divide both sides by 2, which leaves x = 5

and then you would do 3(5) + 40, which is 55

Which expression is equivalent to 8x - 12y + 32?

A. 16(0.5x 4y +32)
B. 16(0.5x - 0.75y + 32)
C. 16(0.5x - 0.75y + 2)
D. 16(0.5x + 4y +2)

Answers

Answer:

It's the third

16(0.5x - 0.75y +2)

Step-by-step explanation:

You just divide everything by 16

8x/16= 1/2x=0.5x

-12y/16 = -3/4x=-0.75x

32/16=2

Answer:

If you are trying to simplify the expression, the answer is -14x^2+8x-37

Step-by-step explanation:

First, keep removing the parentheses.

(x-1)(2-x)+(x^2+5)(x-7) -x^2(x+6)

Next, try expanding the expression.

3x - x^2 - 2+ (x^2+5)(x-7)-x^2(x+6

3x-x^2-2+x^3-7x^2+5x-35-x^2(x+6

3x-x^2-2x^3-7x^2+5x-35-x^3-6x^2

Finally, simplify the expression.

WHOEVER ANSWERS RIGHT GETS BRAINIST

Answers

There are actually two correct answers, one of them is y-4=-0.5(x-4)

First of all, the slope-intercept that can be derived from the points (-4,8) and (4,4) is y=[tex]-\frac{x}{2} +6[/tex], with -0.5 being the slope. To bring this to point-slope form, you must signify the slope and the coordinate intersection. Since there are two coordinates, there are actually two point-slope equations.
