A boy has 11 coins in dimes and quarters. Their value is $1.70. How many of each does he have? Which of the following equations could be used to solve the problem?

Question and answer

Translate the statements into equations. We can use 'x' for dimes and 'y' for quarters. "A boy has 11 coins in dimes and quarters" "Their value is $1.70" To solve this, we can first solve for one of the variables in the first equation, and then plug that into the second equation: Subtract 'x' to both sides: Now plug this value of 'y' into the second equation: 0.10x + 0.25(11 - x) = 1.70 So this equation could be used to solve the problem.

Subtract 'x' to both sides:

Now plug this value of 'y' into the second equation:

0.10x + 0.25(11 - x) = 1.70

So this equation could be used to solve the problem.

Harvey plans to use 5 ft of shelving for four shelves whose lengths are to be a series of consecutive even numbers. Each shelf should be 12, 14, 16, 18 inches. x + 6 would represent the length of the longest shelf. Solution: n+n+2+n+4+n+6=60; 4n+12=60; 4n=48; n=12 inches; 12, 14, 16, 18 inches respectively; The longest shelf was x+6.
