Answer:
A) 4
Step-by-step explanation:
There are a couple of ways to get this but this is how I did it:
1. Multiply the second equation by 1/4 to get the same fraction for y as the one in the first equation
1/4 x + 1/8 y = 2
1/4 (1/3 x + 1/2 y = 4)
1/12 x + 1/8 y = 1
2. Subtract the first equation from the new equation
1/12 x + 1/8 y = 1
<u> - 1/4 x - 1/8 y = -2</u>
-1/6 x= -1
3. Divide both sides by -1/6
<u>-1/6</u> x= <u>-1</u>
-1/6 -1/6
x = 6
4. Substitute 4 in for x in the original equation:
1/4 (6) + 1/8y = 2
6/4 + 1/8y = 2
1/8y = 1/2
y = 4
that's not why this app is for
2x + 4 > 8
Step 1: Subtract 4 from both sides.
2x + 4 − 4 > 8 − 4
2x > 4
Step 2: Divide both sides by 2.
2x/2 > 4/2
x > 2
2x − 3 < 5
Step 1: Add 3 to both sides.
2x − 3 + 3 < 5 + 3
2x < 8
Step 2: Divide both sides by 2.
2x/2 < 8/2
x < 4
Answer:
481
Step-by-step explanation:
Lets say width = x
Length = x+24
Perimeter is 100 so
100=x+24+x+24+x+x
100=4x+48
100-48=4x
52=4x
x=13
So width = 13
Length = 37
37x13=481
