We need to follow PEMDAS.

We need to do the division before we can do the subtract (which becomes into addition because of the signs).

12 - 16/-4

12 - (-4)

12 + 4

16

Your final answer is C. 16.

What is the value for y in the following equation when x = -10?

nadezda [96]

Answer:

B.-38

Step-by-step explanation:

2x - 18 = y ...(1)

x = -10 (Given)

Now,

Put the value of x in equation (1) we get,

2(-10) - 18 = y

-20 - 18 = y

-38 = y

y = -38

Thus, the value of y is -38

The tength of a picture frame is 12 cm more than twice the width. If the perimeter is 204cm, find the

alekssr [168]

Answer:

30cm x 72 cm

Step-by-step explanation:

The perimeter is the measurements of all sides added together. Let's start by dividing the perimeter by 2, so we have the sum of the length and width. This gives us 102cm. Let's call the width x, and the length y. We know y is x times 2 plus 12. (2x + 12) So, we know [x + y = x + (2x + 12)]. So let's solve.

x + y = x + (2x + 12)

102 = x + (2x + 12)

102 = 3x + 12

102 - 12 = 3x + 12 - 12

90 = 3x

90/3 = 3x/3

30 = x

The width is 30cm.
