5x-3y=16
3x-5y=-4
Multiply the first equation by 3; the second one by 5
15x-9y=48
15x-25y=-20
Eq 1 - Eq 2:
-9y+25y=48+20=68
16y=68
4y=17
y=17/4
5x-3y=16
5x-3×17/4=16
5x=16+51/4=(64+51)/4=115/4
x=115/4/5=23/4
x=23/4
Vinny can fill 14 cups to the top at max.
Mathematics: 2/3 of 64 is 42 and 42 divided by 3 is 14.
Answer:
The answer is when they work 4 hours x=4
Step-by-step explanation:
510 + 80x = 650 + 45x
80x - 45x = 650 - 510
35x = 140
x = 140/35
x = 4 hours
Answer:
A
Step-by-step explanation:
Sub in the point given, (3, 1), and check if the equation holds true
7(3) - 8(1) = 13
21 - 8 = 13
13 = 13
The equation held true, therefore, the point (3, 1) is a solution
Answer: The answer is 0.2
Step-by-step explanation:
1 divided by 5 is 0.2 because 1 goes into 5 0.2 times.
Hope this helps!
