Answer:
648 seconds
Step-by-step explanation:
First we need to see how much 60% of 756 is, so we multiply 756 × 0.60 and we get 453.6, so we now just need to see in how many seconds (0.7) we will get 453.6 oz, so we simply divide 453.6 ÷ 0.7 = 648. This is your answer. We can check this by multiplying 648 × 0.7 and getting 453.6

Answer: 4b+9
Step-by-step explanation: add the B's together
So it seems as if the first problem is asking this:

.
If x=0.15, then 11/15*(0.15) is 0.11 or 11/100.
The second problem is asking:

To solve algebraically, you want to get rid of the denominators under the x's. To do so, you want to multiply by the Least Common Multiple (LCM) of the denominators. For 3 and 4, the LCM is 12. Multiply everything by 12 to get:
3x+6=4x+2
Now, solve for x
Subtract 4x from both sides:
-x+6=2
Subtract 6 from both sides:
-x=-4
Multiply by -1 on both sides:
x=4.
