Answer:
A+6+A = 20
A = 7
Step-by-step explanation:
J = number of problems Juana completed
A = number of problems Andy completed
J+A=20
J = A + 6
Replace J with A+6 in the first equation
A+6+A = 20
2A +6 = 20
Subtract 6 from each side
2A +6-6 = 20-6
2A =14
Divide by 2
2A/2 = 14/2
A = 7
Add the 2 and 9 together:
2q+11
Answer:
6^8
Step-by-step explanation:
6^4 * 6^4
We know that a^b* a^c = a^(b+c)
6^4×6^4 = 6^(4+4) = 6^8
Answer:
13 miles
Step-by-step explanation:
The fare for the Uber
Cost= 5+ .5 m
where m is the number of miles
We spent 11.50
11.50 = 5 + .5 m
Subtract 5 from each side
11.5 -5 = 5+.5m -5
6.50 = .5 m
Divide by .5 on each side
6.5/.5 = .5m/.5
13 = m
We went 13 miles
