Answer:
Jack = 48 years old , Lac = 12 years old
Step-by-step explanation:
Jack = 4Lacy
(Jack - 4) + (Lacy - 4) = 52
Now, substitute.
4Lacy - 4 + Lacy - 4 = 52
5Lacy = 60
Lacy = 60/5 = 12
Jack =4Lacy
=4(12)
=48
Answer:
8x^3/5
Step-by-step explanation:
Evaluate the exponent
16x^3/10
Factor 2 out of 16x^3
2(8x^3)/10
Cancel the common factors
Factor 2 out of 10
2(8x^3)/2(5)
Cancel the common factor
(8x^3)/5
Rewrite the expression
8x^3/5
I hope this helps! :)
Answer: rate is a ratio that is used to compare different kinds of quantities. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.
X + (x + 10) = 154
2 x + 10 = 154
2 x = 154-10 = 144
x = 72 (ans)
