Answer:
13 hours
Step-by-step explanation:
Saul cut 4 lawns in 6 hours, to find how long it will take him to mow 9 lawns, we are going to use proportion to solve.
Let x be the time taken Saul to mow 9 lawns
4 lawns = 6 hours
9 lawns = x
cross multiply
4 × x = 9 × 6
4x = 54
Divide both-side of the equation by 4
4x/4 = 54/4
(On the right-hand side of the equation, 4 will cancel-out 4 leaving us with x and on the right - hand side of the equation 54 will be divided by 4)
x = 54/4
x = 13 hours
Therefore, it will take Saul 13 hours to mow 9 lawns.
Answer:A
FOIL
Option D
Given the following question:In order to find the answer, we have to convert the mixed number and then multiply by three, since how Eva needs triple the amount for today's baking.
<u>Convert the improper fraction back into a mixed number:</u>Which means Eva needs "38 1/4 pounds of flour" or option D for today's baking.
first term = a = 3
common ratio = 2nd term ÷ first term
= 12 ÷ 3
r = 4
