Answer:
- The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.
- The solution x = 60 represents the total food bill.
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The food bill (x) plus the tip (16) ;divided by the number of friends (8) , must be equal to the total amount spent (76) divided by the number of friends (8):
Mathematically speaking:
(x+16) /8 = 76/8
(x+16) /8 = 9.5
(x+16) = 9.5 (8)
x+16 = 76
x = 76-16
x= 60 (food bill)
So, the correct options are:
- The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.
(1/8 (x+16) =76/8)
- The solution x = 60 represents the total food bill.

Square of 13 equals 169
Square of 5 equals 25
169-25= 144
144 square root equals 12
Answer: y=-4
Step-by-step explanation:
8(3)+5y=4
24+5y=4
subtract each side by 24
5y=-20
divide by 5
5 y=-4
C. 19.42% because you subtract 389.85 from 314.15 which equals 75.7. So then set it up like an algebraic equation. 389.85x=75.7 divide 75.7 by 389.85 to find the decimal. Then you have to move the decimal to the right two places, since it is a percentage. And then round your answer, so c. 19.42% is your answer. Hope this helped! :)
Answer:
There are no solutions.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x/5+2/3+1x/5=x
4/5x+2/3+1/5x=x
(4/5x+1/5x)+(2/3)=x(Combine Like Terms)
x+23=x
x+23=x
Step 2: Subtract x from both sides.
x+2/3−x=x−x
2/3=0
Step 3: Subtract 2/3 from both sides.
2/3−2/3=0−2/3
0=−2/3
Answer:
There are no solutions.
