20-4y=x²
Answer:20 men
Step-by-step explanation:
let h be the number of hours then
A → C = 150h + 250 ( where C is charge )
B → C = 175h + 150
for 26 hours
A → C = (150 × 26 ) + 250 = 3900 + 250 = $4150
B → C = (175 × 26 ) + 150 = 4550 + 150 = $4700
Attorney A is cheaper for 26 hours, thus better deal
Equate the 2 equations to find hours they charge the same
175h + 150 = 150h + 250 ( subtract 150h from both sides )
25h + 150 = 250 ( subtract 150 from both sides )
25h = 100 ( divide both sides by 25 )
h = 4 ← number of hours when charges for both are equal
Thus Attorney A becomes a better deal at 5 hours
Answer:the football team played 25 games in all
Step-by-step explanation:
Let x represent the total number of matches that the football team played.
The football team won 10 matches out of the total number of matches they played. if their win percentage was 40, it means that
10/x × 100 = 40
1000 = 40x
x = 1000/40 = 25
