Answer:
2x - 4
Step-by-step explanation:
10x - 4 ( 2x + 1 )
= 10x - 8x - 4
= 2x - 4
Multiplying or dividing both sides by a negative number reverses the inequality.
It's y=kx. But 'k' is any constant. So my 'k' can easily be 1/(your k). The key is that when 'x' or 'y' increases by some factor, the other one also increases, by some constant multiple of the same factor. If so, then they're proportional.
Answer: 30 minutes
How: 45 minutes divided by 15 math problems equal 3 minutes per math problem. 3 minutes per math problem times 10 math problems equals 30 minutes on 10 math problems.
45/15=3
3*10=30
Answer:
This equation belongs to One variable linear equation because there is one variable = x and the exponent number is one
solving equations :
x= 44 quarts
