A jar of coins contains only quarters and dimes. The total amount of money in the jar is $4.40, and there are 23 coins. A. Write a system of equations that can be used to find d, the number of dimes, and q, the number of quarters, in the jar.

B. How many quarters are in the jar?

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
