Daisy's mom is 4 times as old as she.The sum of their ages 6 years ago was 28.How is her mother now?

Delvig [45]

Answer:

Step-by-step explanation:

Daisy's mom is 4 times as old as she.

m = 4d

The sum of their ages 6 years ago was 28.

(m - 6) + (d - 6) = 28

Substitute for m = 4d

(4d - 6) + (d - 6) = 28

Combine like terms

5d - 12 = 28

5d = 40

Divide by 5

d = 8

m = 4d

m = 4 * 8

m = 32

Can someone pls explain to me how to do this (^｡^)

Answer:

Area: $\frac{8}{15}$ feet²

Perimeter: $\frac{44}{15} =2 \frac{14}{15}$ feet

Step-by-step explanation:

The formula of finding the area of a rectangle or square is width multiplied by length.

The formula of find the perimeter of a rectangle or square is width+width+length+length

Area: $\frac{4}{5} *\frac{2}{3} = \frac{8}{15}$ feet²

Perimeter:

$\frac{4}{5} +\frac{4}{5} +\frac{2}{3} +\frac{2}{3} =$

$\\\\\frac{12}{15} +\frac{12}{15} +\frac{10}{15} +\frac{10}{15} =\\\\\frac{24}{15} +\frac{20}{15} =\\$

$\frac{44}{15} =2 \frac{14}{15}$
