Answer:

y=29

Step-by-step explanation:

The angles are vertical angles so they are equal.

4y-8 = 79+y

Subtract y from each side

4y-y -8 = 79+y-y

3y -8 = 79

Add 8 to each side

3y-8+8 = 79+8

3y = 87

Divide each side by 3

3y/3 = 87/3

y=29

2 Rita bought three and forty-eight hundredths pounds of bananas at the store. How is this number written in expanded notation?

boyakko [2]

The cost of bananas = $ 3.48

This can be written as :

this number written in expanded notation as : (3 × 1) + (4 × 0.1) + (8 × 0.01)

3+0.4+0.08 = 3.48

Hence, 1st option is correct.
