Maria has five more than twice as many hats as Beth. Together they have 26 hats. How many hats does Maria have?

1 answer:

4 0

Maria has 19 hats.

b=beth
m=maria
Equations: 2b+5=m
b+m=26

plug in 2b+5 for m in equation 2: b+2b+5=26
add like terms: 3b+5=26
subtract 5 from both sides: 3b=21
Divide 3 from both sides: b=7
now plug in 7 for b: 7+m=26
subtract 7 from both sides: m=19
m=Maria
therefore Maria has 19 hats

Answer:

They need 2 and 1/2 rolls.

Step-by-step explanation:

Area = length x width

A = l x w

A = 20 x 3

A = 60 ft²

If 60 ft² = 1 roll

What about 150 ft² = ?
