Answer:
B
Step-by-step explanation:
So when I was doing the math Equation 2 and Equation 3 were it so I hope that helped and I also hope I did my math right too XD
An algebraic expression is, obviously, an expression with a variable.
"A number" would represent a variable, which, in this case, we'll use y.
So, 15 decreased by twice x.
15 - y x 2 =
I hope this helped :)
m = 5a
m + a = 30
Because we already know the value of m, we can find the value of a.
5a + a = 30
<em><u>Combine like terms.</u></em>
6a = 30
<em><u>Divide both sides by 6</u></em>
a = 5
Now that we know the value of a, we can find the true value of m.
m = 5a
m = 5 * 5
m = 25
Aisha is 5 years old, and Aisha's mother is 25 years old. (This is your answer.)
