Answer:
DF = 57
Step-by-step explanation:
DE + EF = DF
(4x + 10) + (2x - 1) = 9x - 15
Combine like terms on the left side
6x + 9 = 9x - 15
Subtract 6x on both sides
9 = 3x - 15
Add 15 on both sides
24 = 3x
Divide by 3 on both sides
x = 8
DF = 9x - 15 = 9(8) - 15 = 72 - 15 = 57
Checking:
(4(8) + 10) + (2(8) - 1) = 9(8) - 15
(32 + 10) + (16 - 1) = 72 - 15
58 - 1 = 72 - 15
57 = 57
Add up all the reservations for the whole week:-
= 5+3+4+7+26+30+9 = 84
Number for Friday , Saturday = 26+30 = 56
so percentage for these 2 days = (56*100) / 84 = 14 * 100 / 21 = 2/3 * 100
= 66 2/3 % answer
Answer:
hope you can now substitute and find y
