Answer:
a=1.5b
Step-by-step explanation:
Add 2b on both sides to get 7a=5a+3b
Subtract 5a
2a=3b
divide by 2
a=1.5b
Answer:B and D
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
Add 4+1=5 then do 5÷5=1
We know that the diameter of the wheel is 80cm. Thus we can find the circumference of the wheel by the equation C=2(pi)r or, knowing that the Diameter is 2r, C=D(pi).
Now, we know that the circumference of the wheel is 80(pi)cm.
If the wheel rotates 170 times, that means we multiply the circumference of the wheel by 170 to receive the answer.
80 x 170 x pi = about 42725.66cm
we then can divide our answer by 100 to convert to meters -->
(42725.66cm)(1m/100cm) = 427.2566 which we round to 427m
Hope this helped!
