K to the 6th power, because you can add k to k to the 5th power to make k to the 6th, and n to the 5th and n to the -5th cancel each other out.

You are saving money for a new phone. You must have at least $800 saved up in

NeX [460]

Let number of hours needed to work = x

Multiply number of hours by rate: 15x

Add what you already have saved:

15x + 215

This needs to equal at least 800:

The equation becomes:

15x + 215 >= 800

Solve for x:

15x + 215 >= 800

Subtract 215 from both sides

15x >= 585

Divide both sides by 15

X >= 39

They have to work at least 39 hours.

There are 550 students at Martin Middle School. One bundred and eighty- seven students walk to school. what percent of the stude

Anvisha [2.4K]

For a question like this, all you have to do is remember that a percentage is simply a fraction expressed as a decimal. So, all we have to do is:
$\frac{187}{550}$ , and then multiply our decimal answer by 100 to get the percentage:
$\frac{187}{550}$ = 0.34
0.34 x 100 = 34
Therefore 34% of the students walk to school.
I hope this helped and remember to please try and understand the maths that got the answer, not just writing the answer down :))

Solve for x. Simplify completely.<br> x^2-9=55

djverab [1.8K]

★ Exponential reduction ★

$x {}^{2} - 9 = 55 \\ x {}^{2} = 55 + 9 = 64 \\ x {}^{2} = 64 = ( + 8) {}^{2} \\ x = + 8 \\$
we didn't considered -8 because square root of any real number is always positive , or it's yours choice to deal with minus 8 also :)
