15 is 25% of 60 because 25% is .25 in decimal form which 1/4 in fraction form and 1/4(60)=15
-4x - 7 +10x = -7 + 6x
Combine like terms on left side.
6x - 7 = -7 + 6x
Add 7 to both sides.
6x = 6x
Subtract 6x from both sides.
0 = 0
This means there are infinitely many solutions.

Answer:
5.5
Step-by-step explanation:
y = 0.5x + 5
Use the slope-intercept form to find the slope and y-intercept.
<em>Slope: 0.5
</em>
<em>y-intercept: 5
</em>
Any line can be graphed using two points. Select two <em>x</em> values, and plug them into the equation to find the corresponding values.
To find the y intercept using the equation of the line, plug in 0 for the <em>x</em> variable and solve for y.
<em>y = 0.5(0) + 5
</em>
<em>y = 5</em>
To graph the y intercept using the equation of the line, plug in 1 for the x variable and solve for y.
<em>y = 0.5(1) + 5
</em>
<em>y = 5.5
</em>
Which means when x is 0, y intercept at 5 and when x is 1 y intercept at 5.5. Graph the line using the slope and the y-intercept, or the points.
This tells us, in practical terms, that, for every one unit that the x-variable increases (that is, moves over to the right), the y-variable increases (that is, goes up) by 50% of a unit.
