Multiply 42 times 150 percent or 42×1.5 which would be 63
Answer:
x = 1.8
Step-by-step explanation:
2 ( 4x-3) - 8 = 4-2x
Distribute
8x -6 -8 = 4- 2x
Combine like terms
8x - 14 = 4 - 2x
Add 2x to each side
8x - 14 +2x = 4-2x+2x
10x-14 = 4
Add 14 to each side
10x-14+14 = 4+14
10x = 18
Divide by 10
10x/10 = 18/10
x = 1.8

Answer:
x = 7, y = 6
Step-by-step explanation:
solve for y for the first equation
2x + y = 20
-2x -2x , eliminate 2x
y = 20-2x
now that we have found y, substitute the y in for the second equation
-5y = -6x + 12
-5(20-2x) = -6x + 12, we just changed y into 20-2x. remember that we are multiplying all of 20 - 2x by -5
-100+10x = -6x + 12, we multiplied everything from the parathesis by -5
+100 + 100, eliminate -100
10x = -6x + 112
+6x +6x , eliminate 6x
16x = 112 , solve for x
x = 7
then y = 20 - 2x = 20 - 2*7 = 6
check:
2 * 7 + 6 = 20
20 = 20
-5 * 6 = -6 * 7 + 12
-30 = -42 + 12
-30 = -30
Answer:
B.) -7/1
Step-by-step explanation:
Finding the slope we use: y2 - y1/x2 - x1
m = -1 - 6/-3 - (-4)
m = -7/-3 + 4
m = -7/1
