1. $2\cdot(8-3)-6=2\cdot5-6=4$

2. $14c-6=22\implies14c=28\implies c=2$

3. $2x+18=5x\implies 3x=18\implies x=6$

4. $18-c+9c+6=24+8c$

5. $8x=-56\implies x=-7$

Hope this helps :)

What is the quotient of -8a^8b^-2/ 10a^-4b^-10 in simplified form?

postnew [5]

Here are a few rules with exponents that you need to know:

Dividing exponents of the same base: $\frac{x^m}{x^n}=x^{m-n}$

For this, divide:

$\frac{-8a^8b^{-2}}{10a^{-4}b^{-10}}=\frac{-8}{10}a^{8-(-4)}b^{-2-(-10)}=-\frac{4}{5}a^{12}b^8$

<u>Your final answer is $-\frac{4}{5}a^{12}b^8$ </u>

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 675 square feet. The width of the basem

artcher [175]

I am reading this correctly, the width = 1/3 of the length?

If this is the case, and we know that the area is 675, the equation is as follows.

Width x Length = 675 ft2

X = length

1/3 X x X = 675 ft2

To solve for X we have to multiply both sides by 3.

X square 2 = 2601 square feet.

Take the square of each side.

X = 225 sqare feet.

I hope this helps, let me know if you have any questions.

At the fair 4 employees were paid $8.75 an hour to work at a funnel cake stand. They worked 8 hours at regular pay then for 5 ho

nordsb [41]

Answer:

$125.25

Step-by-step explanation:

8.75*h+11.25*e

h is hours regular pay and e is extra pay for overtime. Since its an extra $2.50 for overtime, add that to the regular pay. Put in the hours:

$8.75*8+11.25*5$

Simplify by multiplying 8.75 by 8

$70+11.25*5$

Simplify by multiplying 11.25 by 5

$70+56.25$

Add

$70+56.25=126.25$

Since it says how much did each earn, as in individually, leave it as it is (unless regular pay was $2.18 an hour, which would be a rip-off). I'm pretty sure including the number of employees was meant to throw you off.
