What percent of 69 is 87? ​
dem82 [27]

Answer:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 69 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 69, so we can write it down as 100%=69.

4. We know, that x% equals 87 of the output value, so we can write it down as x%=87.

5. Now we have two simple equations:

1) 100%=69

2) x%=87

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=69/87

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87 is what percent of 69

100%/x%=69/87

(100/x)*x=(69/87)*x       - we multiply both sides of the equation by x

100=0.79310344827586*x       - we divide both sides of the equation by (0.79310344827586) to get x

100/0.79310344827586=x

126.08695652174=x

x=126.08695652174

now we have:

87 is 126.08695652174% of 69

Step-by-step explanation:

Hope it helps :)

Write the equation y=4x+9 in standard form using integers.
rosijanka [135]

Answer:

4x-y=-9

Step-by-step explanation:

The standard form of an equation is when both variables, x & y, are on the same side of the equation with a number on the other side.

To transform this equation from slope-intercept form to standard form, just switch sides for the y and the 9 like follows.

4x-y=-9

I hope this helped you :D
