Answer:

We need to solve each equation:

1. 2x - 5 = x

2x - x = 5

x = 5 ✅

2. -3b + 1 = 3b -5

5 + 1 = 3b + 3b

6 = 6b

b = 1 ✅

3. (1/2)t + 7 = (3/2)t - 4

t + 14 = 3t - 8

2t = 22

t = 11 ✅

4. -2.3 + 1.2x = 5.9 - 2.9x

2.9x + 1.2x = 5.9 + 2.3

4.1x = 8.2

x = 2 ✅

5. -7y -21 = -3y - 21

-21 + 21 = -3y + 7y

0 = 4y

y = 0 ✅

Answer:

16.5 hours

Step-by-step explanation:

The bicycle costs $240. Eva already has $42. She is making $12 per hour.

240 = 12x + 42

Solve for x to find out how many hours Eva needs to work to buy the bicycle.

240 = 12x + 42

240 - 42 = (12x + 42) - 42

198 = 12x

198/12 = (12x)/12

16.5 = x

Eva needs to work 16.5 hours to be able to buy the bikw.

A border to surround a picture is to be cut from a 10 1/2 in by 10 1/2 in mat board. If picture is 8 3/4 in by 8 3/4 in what is

Lilit [14]

Since the dimensions of the length and width are equal, then the board and the picture are squares. The width of the board is the margin surrounding the picture. Let's denote the width to be x. The length of the picture plus the length of the width at both ends should equal the length of the board. So, the equation should be:

10 1/2 in = 8 3/4 + 2x
Solving for x
x = 7/8 inches
