Question

1. Addition:

Answer 1

Answer:

See explanation.

Step-by-step explanation:

1. Subtraction

a. x - 2 = 10

x = 12

12 - 2 = 10.

b. s - 4 = 6

s = 10

10 - 4 = 6

c. y - 10 = 24

y = 34

34 - 10 = 24

d. t - 3 = 9.

t = 12

12 - 3 = 9

2. Addition

a. x + 2 = 10

x = 8

8 + 2 = 10

b. s + 4 = 6

s = 2

2 + 4 = 6

c. y + 10 = 24

y = 14

14 + 10 = 24

d. t + 3 = 9

t = 6

6 + 3 = 9

3. Multiplying Fractions

a. 1/2x = 10

x = 20

1/2(20) = 10

b. 1/4s = 8

s = 32

1/4(32) = 8

c. 1/3t = 6

t = 18

1/3(18) = 6

d. 1/5y = 20

y = 100

1/5(100) = 20

4. Multiplying Whole Numbers

a. 4x = 32

x = 8

4 * 8 = 32

b. 13x = 39

x = 3

13 * 3 = 39

c. 5x = 25

x = 5

$\sqrt{25}$ = 5

5 * 5 = 25

d. 10x = 100

x = 10

$10\sqrt{100}$ = 10

10 * 10 = 100.

Hope this helps.
