Step-by-step explanation:
2/root 9=2/3 = 0.6666666667
A(h)=4h+70, A(h)=dollars to rent for h hours, h=hours rented.
B(h)=5h+60, same variable explanations...
....
To compare the two values at 6 hours you have:
A(6)=4(6)+70=24+70=$94
B(6)=5(6)+60=30+60=$90
So at 6 hours Company B would charge $4 less than Company A
...
Savings at 7 hours of rental by using B instead of A is:
S(h)=A(h)-B(h)
S(h)=4h+70-5h-60
S(h)=-h+10
S(7)=-7+10=$3
So at 7 hours, Company B saves you $3.
Answer:
Your friend scored 62
Step-by-step explanation:
Let your friend's score = x
140/100 * x = 86.8 Starting statement
1.4x = 86.8 % has been changed to a decimal
1.4x = 86.8/1.4 Divide by 1.4
x = 86.8/1.4
x = 62 Answer

Answer:
NO SOLUTION
Step-by-step explanation:
Solve this system by substitution:
Replace y in the first equation with -2x - 2:
2x + (-2x - 2) = 2, or
2x - 2x - 2 = 2
0 = 4 This is not possible, so this system has NO SOLUTION.
