Answer:
3 1/5 hours
Step-by-step explanation:
1/4 book in 1 1/3 hours.
1 1/3 = 4/3
1/4 book in 4/3 hours
We can set up a proportion.
1/4 book is to 4/3 hours as 3/5 book is to x hours.
(1/4) / (4/3) = (3/5) / x
Cross multiply:
(1/4)x = 4/3 × 3/5
(1/4)x = 12/15
Multiply both sides by 4.
x = 48/15
Reduce:
x = 16/5
x = 15/5 + 1/5
x = 3 1/5
Answer: 3 1/5 hours
Answer:
(0,7)
Step-by-step explanation:
(I'm assuming you have to solve the system of equations)
3x -10y = -70
4x +9y = 63
Solving by elimination.
Eliminate x first, so we need the x-component of both equations to have the same number but opposite sign. So i'm going to multiply the first by -4 and the second by +3.
//I could have also done +3 to first and -4 to second
-4(3x -10y = -70)
3(4x +9y = 63)
-12x +40y = 280
12x +27y = 189
Add the equations //x's cancel
67y = 469
Divide both side by 67, y=7
Plug in y into any original equation to solve to x
3x - 10(7) = -70
3x -70 = -70
3x = 0
x=0
