Answer:
Noah is 17 and Tina is 7.
Why?
Let t represent Tina’s age.
So, 2t + 3 is Noah’s age.
This is your equation;
2t + 3 + t = 24
Now, simplify so t is on one side.
3t = 24 - 3
3t = 21
t = 21/3
t = 7
Tina’s age is 7, and Noah (according to the expression made for him) is 17.
Check:
7 + 17 = 24
Answer:
Step-by-step explanation:
2/5+ (7 1/5) = 3 +(-7) + 2/5 +(- 1/5)=
38/5 = -19/5
Answer:
c=-24
Step-by-step explanation:
You should perform the inverse of addition and multiplication
The inverse of addition is subtraction so we subtract 4 on both sides:
4-4-c=26-4
Which will be
-c=24
Divide by -1 since the inverse of multiplication is division
-c/-1=24/-1
So the answer will be:
c=-24
