Answer:
a = 0
Step-by-step explanation:
3(4a+7)=5(2a+4)+1 Distribute 3 through the parentheses
- > 12a + 21 = 5(2a + 4) +1
5(2a + 4) +1 --> 10a + 20 + 1
12a + 21 = 10a + 20 + 1 --> 12a + 21 = 10a + 21 --> 12a = 10a
12a - 10a = 0 --> 2a = 0
Divide both sides of the equation by 2 --> a = 0
Answer:
The second one
Step-by-step explanation:
Answer:
B= 70, C= 50
Step-by-step explanation:

X=3
C: 15×3+5=50
B: 22×3 +4= 70
Answer:
30.14
Step-by-step explanation:
- The formula for cirumference is 2(pi)r
- If the diameter equals 9.6 then the radius is 4.8
- 4.8 times 2 equals 9.6
- 9.6 times 3.14(pi) equals 30.144 which could be rounded to 30.14
