Marrrta [24]

Answer:

20 years apart.

Step-by-step explanation:

Daughter is 10 years old, and mother is 3 times older. This makes mother 30 years old.  There is a 20 year difference between them.

Ten years later, the daughter is 20 years old. Since the mother is 20 years older, she is now 40, which is 2 times older than the daughter.

What is the valuable of x in the equation 1.8-3.7x=-4.2x+0.3
Mumz [18]

Answer:

x = 3

Step-by-step explanation:

1.8 - 3.7x = -4.2x + 0.3

add -4.2x to both sides

1.8 - 0.5x = 0.3

subtract 1.8 from both sides

-0.5x = 0.3 - 1.8

-0.5x = -1.5

divide by -0.5 on both sides

x = 3

GREAT JOB!!!! YOU GOT IT!!! =)

horrorfan [7]

Let:

100%---------------->24h

30%------------------>xh

Using cross multiplication:

\begin{gathered} \frac{100}{30}=\frac{24}{x} \\ solve_{\text{ }}for_{\text{ }}x\colon \\ x=\frac{30\cdot24}{100} \\ x=\frac{720}{100}=7.2h \end{gathered}
