Answer:5
Step-by-step explanation:
4(x+2)=28
x+2=7
x=5
Answer:
A direct variation is when x and y (or f(x) and x) are directly proportional to each other... For example, if you have a chart that says x and y, and in the x column is 1, 2 and 3, and the y column says 2, 4 and 6... then you know it's proportional because for each x, y increases by 2
Step-by-step explanation:
Set up a porportion,
3/5 hours / 2/5 square yards
1 hour / x square yards
simplify by cross multiplying
3/5x <span>= 2/5(1).
</span>3/5x <span>= 2/5.
</span> 3/5/3/5x = <span>2/5/3/5
x </span><span>= 10/15
</span>x <span>= 2/3
</span><span>
so she can paint </span><span>2/3 square yards in 1 hour. hope this helps!</span><span>

I am pretty sure it is 0.95. This is because 0.5 is half of a whole. So, half of 1.9 is 0.95. :) I hope this helped.
