in this problem, we are going to translate our words into a mathematical equation, solve the equation and then answer the question. So we have, the father is three years older than the mother, so is three, is our answer there for this equation. So if we take the oldest minus the youngest, It would give us a difference of three. So since the father is older, we're going to say the father's age minus the mother's age is three, So we know that the mother is 42 years old, So the father minus the 42 would give us three. So to solve for F, we're going to use the addition property of equality and add 42 to both sides. So F -40 to plus 42 is F and Add 42 to both sides, and three plus 42 is 45. So this means that the father is 45 years old.
So they had 17 left over and one Apple was cut into 8 slices. 8 goes into 17 2 times with one left over. So it would be 2 whole apples with 1 slice left over. So 17 slices converts to 2 wholes and 1 part (slice)
