Question

Please answer all of them

Answer 1

a. x = 5/2

b. y = 16.5

c. z = 12

Explanation:

Answer 2

1) x = 2.5

b) y = 12.9

c) z = 12

d) 2.75 = w or 2
`(3)/(4)` = w

e) t = 4

Explanation:

a)

2x = 5

divide both sides of the equation by 2

2x/2 = 5/2

x = 5/2

x = 2.5

b)

y + 1.8 = 14.7

subtract 1.8 from both sides of the equation

y + 1.8 - 1.8 = 14.7 - 1.8

y = 14.7 - 1.8

y = 12.9

c)

6 = 1/2z

divide both sides by 1/2 or multiply both sides by 2

6*2 = 1/2z * 2

6*2 = z

12 = z

d)

3.25 = 0.5 + w

subtract 0.5 from both sides of the equation

3.25 - 0.5 = 0.5 + 2 - 0.5

3.25 - 0.5 = w

2.75 = w

or

2
`(3)/(4)` = w

e)

2.5t = 10

t = 10/2.5

t = 4
