1 answer:

3 0

Answer: -8

Explanation:

This question is fairly simple. All you have to do is substitute and solve using PEMDAS.

x+x3-4x4

Substitute by replacing the x with 2 since it tells us that x=2.

You would ended up with

2+2(3)-4x4

Now use PEMDAS to solve!

2+6-4x4

2+6-16

8-16

-8

1 fourth B minus 10 equals 7

creativ13 [48]

$\frac{1}{4}$ b - 10 = 7
Take 10 to the other side.

$\frac{1}{4}$ b = 17

Multiply by 4 to isolate b
$\frac{1}{4}$ b × 4 = 17 × 4

4 and 4 cancels out

b = 68
