Answer:

x=3 ; y=1

Step-by-step explanation:

y=3x-8 ---- 1

x+y = 4. ----- 2

Put value of y from equation 1 in equation 2,

x+3x-8 = 4

Adding x terms,

4x-8 = 4

Adding 8 on both the sides,

4x = 12

Dividing by 4,

x = 3

Put the value of x in equation 2,

3 + y = 4

Subtract 3 from both the sides,

y = 4-3 = 1

x=3 ; y=1

pentagon [3]

Answer:

4 years

Step-by-step explanation:

Note that:

1 foot = 12 inches

1 2/3 feet = x inches

We cross multiply

1 foot × x inches = 1 2/3 feet × 12 inches

x inches = 1 2/3 feet × 12 inches/1 foot

x inches = 5/3 × 12 inches

x inches = 20 inches

A tree grows 5 inches each year. How many years will it take for the tree to be 1 2/3 feet tall = 20 inches

This is calculated as

5 inches = 1 year

20 inches = x year

Cross Multiply

5x = 20 inches × 1 year

x = 20/5

x = 4 years

It would take the tree 4 years to be 1 2/3 feet tall
