Answer:
Simplifying
12t + -8t = 0
Combine like terms: 12t + -8t = 4t
4t = 0
Solving
4t = 0
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Divide each side by '4'.
t = 0
Simplifying
t = 0
Step-by-step explanation:
Let x = # of Republicans
x + 4 = # of Democrats
x + x + 4 = 100
x = 48
48 + 4 = 52
There are 52 Democrats and 48 Republicans.
Answer:
48 yr. old
Step-by-step explanation:
Assume daughter is 4 and mom is 10 times her age, so mom is 40.
10 (woman) * 4 (daughter's age) = 40 yr. old mom
Present day...
40 (yr old mom) + 8 (yrs later) = 48 yr. old mom today
4 (yr old daughter) + 8 (yrs later) = 12 yr. old daughter today
So, if mom is 4 times as her daughter's age today...
48 (yr. old mom) / 12 (yr. old daughter) = 4
