Answer:
14 1/2
Step-by-step explanation:
6a-15=72
+15 on both sides
6a = 87
Divide by 6 on both sides
a = 14 1/2
Answer:
solve the last equation for b then solve the first equation for a, after you have a plug that in to find c.
Step-by-step explanation:
a=5+b
c=2a
a+b+c=225
(5+b)+b+(2a)=225
(5+b)+b+[2(5+b)]=225
13y + 25 = 64
- 25 -25
13y = 39
13/13 39/13
y = 3
4y - 7
4(3) - 7
12 - 7
5
The answer is: 5
Answer:
x = 60°
