Answer:
50
Step-by-step explanation:
You have the following information:
48/100 of x = 24
(48/100)*x=24
x= 24:(48/100)=24*(100/48)=100/2=50
The value of x and y is y= 3/4 and x= -1/2
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given equations:
2x+8y=5........(1)
24x-4y=-15...........(2)
Multiply equation (1) by 12, we get
24x + 96y = 60.....(3)
From (2) and (3), we get
-4y-96y= -15-60
-100 y= -75
y= -75/-100
y= 3/4
and 2x+8y=5
2x + 8 (3/4) =5
2x + 6 = 5
2x= -1
x= -1/2

Answer:
2
Step-by-step explanation:
y= 2x
How did i come to this conclusion??
-2 times something gives me -4
so I can use a variable to find it!!!
-4= -2x
-4/-2 =x
2=x
You would get the same answer for each value
Compute the unit rates.
Tank A:
(5/8 gal) / (1/2 min) = 10/8 gal/min = 5/4 gal/min = 1.25 gal/min
Tank B:
(3/5 gal) / (1/4 min) = 12/5 gal/min = 2.2 gal/min
So tank B is filling faster.
