Answer:
x = 41 3/4
Step-by-step explanation:
(2 1/2)x -(3/4)(2x +5) = 38
(2 1/2)x -(1 1/2)x -15/4 = 38 . . . . use the distributive property
x = 38 +3 3/4 . . . . . . add 15/4
x = 41 3/4

Another way to solve this is to "clear fractions" by multiplying the whole equation by 4:
10x -3(2x +5) = 152
4x -15 = 152 . . . . eliminate parentheses
4x = 167 . . . . . . . add 15
x = 41 3/4 . . . . . . divide by 4
All you would do is divide for this problem so,
13.75 ÷ 5 = 2.75
So one pack would cost 2.75

Answer:
4 balloons
Step-by-step explanation:
3:6= 1:2
2*3= no. of guest, 1*3= no. of balloons
SO
2*4 (8)= number so guests, and 1*4 (4)= number of balloons
Answer:
5
Step-by-step explanation:
Y=-4x because all you have to do is move the variable to the right by adding its opposite to both sides. So 4x+y-4x=0-4x. Then eliminate the opposites y=0-4x
