Can somebody me? write the phrase as an expression. then evaluate when x = 2 and y = 10. #1 twelve more than the product of 5 and a number x. #2 15 decreased by the product of a number x and 4. #3 you eat 5 slices of bread. your friend eats 2 slices fewer than you eat. write an expression that describes the number of slices your friend eats. #4 your uncle is 2 years older than 3 times your age. a. you are x years old. write an expression that describes your uncle's age. b. you are 12 years old. how old is your uncle.

Step-by-step explanation:

1) Twelve more than the product of 5 and a number x. This is expressed as

y = 5x + 12

when x = 2,

y = 5×2 +12 = 22

and when y = 10

10 = 5x + 12

5x = - 2

x = -2/5

2) 15 decreased by the product of a number x and 4. This is expressed as

y = 15 - 4x

When x = 2

y = 15 - 4×2 = 7

When y = 10

10 = 15 - 4x

4x = 15 - 10 = 5

x = 5/4

3) You eat 5 slices of bread. Your friend eats 2 slices fewer than you eat.

Let y represent the number of slices that your friend ate. The expression will be

y = 5 - 3 = 2

y = 2

4) Your uncle is 2 years older than 3 times your age. A. You are x years old. Let your uncle be y years old. Therefore,

y = 3x + 2

If you are 12 years old, your uncle well be

3×12 + 2 = 38 years old
