Write a proportion. Then solve. Where necessary, round to the nearest tenth or tenth of a percent.
38% of n is 33.44. What is n?
a 88
b 79
c 99
d 68

38% of 88 is 33.44. 33.44/n = 38/100 38n = 100(33.44) 38n = 3344 n = 3344/38 n = 88

38% of 88 is 33.44.

33.44/n = 38/100

38n = 100(33.44)

38n = 3344

n = 3344/38

n = 88

33.44/n = 38/100

38n = 100(33.44)

38n = 3344

n = 3344/38

n = 88

User: What is the solution for the system for #1 on the worksheet? y = -2x + 4 2x - 2y = 4
**Weegy:**
y = -2x + 4
2x - 2y = 4
2x - 2(-2x + 4) = 4
2x + 4x - 8 = 4
6x = 4 + 8
6x = 12
x = 12/6
x = 2
y = -2(2) + 4
y = -4 + 4
y = 0
Solution set: (2, 0)
**User:** What is the slope and y-intercept for each equation in the system given?
1.) y = -2x + 4
2.) 2x - 2y = 4
a 1.) m = -2, y-int (0,4) 2.) m = 2, y-int (0,2)
b 1.) m = -2, y-int (0,4) 2.) m = 1, y-int (0,-2)
c 1.) m = -2, y-int (0,4) 2.) m = -1, y-int (0,2)

1.) y = -2x + 4

m = -2, y-int (0, 4)

2.) 2x - 2y = 4

(-2y = -2x + 4)/(-2)

y = x - 2

m = 1, y-int (0, -2)

m = -2, y-int (0, 4)

2.) 2x - 2y = 4

(-2y = -2x + 4)/(-2)

y = x - 2

m = 1, y-int (0, -2)

In question #2, it says to solve the system by substitution.
x = -3y - 8
-2x - 4y = 9
Which is the correct equation after the substitution is made?
a 6y- 8 - 4y = 9
b -2(-3y - 8) - 4y = 9
c -2x = 4(-3y - 8) = 9
**Weegy:** x=-3y-8_ -2x-4y=9
x=-3y-8_ -2(-3y-8)-4y=9...
So B) -2(-3y - 8) - 4y = 9 is the answer. (More)
