Answer: that is not a question
Step-by-step explanation:
Answer:
2b -a
a-2c
Step-by-step explanation:
a = b+c
We want to find b-c
Solve the first equation for b
b = a-c
and for c
c = a-b
b-c in terms of b and a
using c = a-b
b - (a-b)
Distribute the minus sign
b - a +b
Combine like terms
2b -a
b-c in terms of c and a
using b = a-c
(a-c) -c
a-c -c
Combine like terms
a-2c
Answer:
Fifteen and six hundredths
Step-by-step explanation:
Answer:
76
Step-by-step explanation:
We know that the two angles must add up to 90 which means that
12+x-2=90
solve for x
14+x=90
x= 76
