Answer:
24$
Step-by-step explanation:
$80 - $32 - $24 = $24
-3x - 4y - 2z = 0
x + 3y + 2z = 1
-2x - y = 1
-4x - 4y - 2z = 10
3x + 4y +2z= 0
-x = 10. x = -10
-2(-10) - y = 1
20 - y = 1
-y = -19
y = 19
-10 + 3(19) + 2z = 1
-10 + 57 + 2z = 1
47 + 2z = 1
2z = -46
z= -23
check: 2(-10)+2(19)-23=-5
-20+38-23=-5
-43+38=-5
-5=-5
45 times the numerator plus the denominator is most likely going to equal the same amount as if it were doubled.
To find an area of a rectangle, we use this method: A = lw (length x width)
We need to replace a(rea) with 48.
48 = lw.
The following expressions can be used:
1 x 48.
2 x 24.
3 x 16.
4 x 12.
6 x 8.
8 x 6.
12 x 4.
16 x 3.
24 x 2.
48 x 1.
This is a simply problem. Just divide both sides the coefficient of x. Which is -2.
And the answer will be x = -4
