I think the value of y would be 9
because if you put 3 in place of x the equation would be
6.4(3)+2.8y then you would simplify it to 19.2+2.8y
19.2-44.4=25.5
25.2/2.8=9 which is the value of y
answer=9
Answer:
-6
Step-by-step explanation:
1. Always do the parentheses first. solve 8-2 to get 6.
-(8-2) = -(6) = -6
5(20) + 4y = 216
100 + 4y = 216
4y = 216 - 100
4y = 116
y = 116/4
y = 29.....so they sold 29 four-dollar yogurts + 20 five-dollar yogurts....for a total of 49 yogurts sold <==
He had to go over by 1/4 of a cup.
1 cup =128
1/4 of a cup =32 grams
5y + 3 > -7 y + 13
Subtract 3 from both sides
5y > -7y + 13 - 3
Add 7y to both sides
5y + 7y > 13 - 3
12y > 10
Divide by 12, which is positive so the sign doesn't flip
y > 10/12 = 5/6
Answer: y > 5/6
