Answer: Neither one is correct
Step-by-step explanation:
We don't know what we are actually comparing to: is it inches:feet or feet:inches? With the info provided, we can't decide which one is correct.
Outcomes:
1. Inches:feet constant of proportionality is 12,
2.feet:inches constant of proportionality is 1/12
Michael is x. Michelle is y.
x+y=27
x-5=y
Substitute y
x+(x-5)= 27
2x-5=27
2x=32
x=16
Plug in x value
(16)+y=27
y=11
Final answer: Michael-16, Michelle-11
Answer:
Patricia is 47 years old
Sharla is 55 years old
Step-by-step explanation:
Rewrite the first sentence as an equation: (S= Sharla) (P= Patricia)
S=P+8
Rewrite the second sentence as an equation:
S+P=102
1) Substitute P+8 as Sharla in the second equation:
P+8+P=102
2) Combine alike terms:
2P+8=102
3) Subtract 8 from both sides:
2P=94
4) Divide both sides by 2:
P=47
5) Substitute 47 as P in the <u>First</u> equation:
S=47+8
6) Solve:
S=55
First you have to write the equation...(x+7)5=30
then solve; so, x= -1
