kifflom [539]3 years ago
8 0

Step-by-step explanation:

5x+2y=-11

2x+2y=5

so you find values that match or can multiply by something to match-2

5x+2y=-11

- 2x+2y=5

=3x+0y=-16

3x/3=-16/3

x=5 1/3

then substitute x in one of the equations to get y

What is the answer 3x+(x-8)=120
Yuliya22 [10]
Combine like terms.

3x+(x-8)= 120

4x-8= 120

Add 8 to both sides.

4x= 128

Divide by 4 into both sides.

x= 32

I hope this helps!

Nookie1986 [14]

Answer:

D: 768

Step-by-step explanation:

First, he divides a piece of paper in half.

1 \div  \frac{1}{2}  = 2

He gets two pieces.

Next, he cuts each of the pieces into three parts.

2 \div  \frac{1}{3}  = 6

Thirdly, he cuts each of the 6 pieces into 8 pieces.

6 \div  \frac{1}{8}  = 48

Lastly, he divides each piece into 16 parts.

48 \div  \frac{1}{16}  = 768

He has 768 pieces in the end. (D)

Answer:

See explanation

Step-by-step explanation:

From the attachment, the question has been answered. However, the explanation is as follows;

Given that

(x,y) = (7,4)

This means that

x = 7

y = 4

See attachment (1)

Step 1: Locate point 7 on the x axis

Step 2: Locate point 4 on the y axis

Trace these two points until they intersect.

The point at which they intersect, is the required point (7,4) --See attachment (2)
