Answer:
115 sirrrrr
Step-by-step explanation:
a +b = 7
a-b = 3
Rewrite the second equation as a = 3+b
Replace a in the first equation with that:
3+b + b = 7
Simplify:
3 +2b = 7
Subtract 3 from both sides:
2b = 4
Divide both sides by 2:
b = 4/2 = 2
Now replace b in the first equation with 2 to solve for a:
a + 2 =7
a = 7-2 = 5
so you now have a and b.
Now solve the given equation:
2^a * 2^b
2^5 * 2^2
32*4
128
The answer is 128.
Answer:
y = 10 PLEASE GIVE BRAINLIEST
Step-by-step explanation:
The angles of this triangle should all add up to 180 degrees.
There are 3 angles so 180 ÷ 3 = 60. Each angle will = 60 degrees.
To find y:
5y + 10 = 60
5y = 60 - 10
5y = 50
y = 50 ÷ 5
y = 10
