Answer: 7.2
Step-by-step explanation: Cuz 5.6+12.9=18.5, 18.5-11.3=7.2
Step-by-step explanation:
y = ( 7 + 4 k ) x
x = y /( 7 + 4 k )
Firstly let’s assume she is correct and use an equal sign:
1/2(12x + 24) = 3(2x + 4)
Now simplify both sides:
1/2 • 12x = 6x
1/2 • 24 = 12
6x + 12
3 • 2x = 6x
3 • 4 = 12
6x + 12
And:
6x + 12 = 6x + 12
Therefore they are equivalent, she is correct.
Answer:
A. y = -3/2x + 1
B. y = -5/3x + 10
C. y = -x + 6/5
Step-by-step explanation:
A. You just have to isolate the y so divide by 4: y = -3/2x + 1
B. 3y = -5x + 30
Divide by 3: y = -5/3x + 10
C. -5x + 6 = 5y
Divide by 5: -1x + 6/5 = y OR y = -x + 6/5
