Peter hired a cleaning company to clean his house. The cleaning company charges a fixed fee of $15 plus $17 per hour to clean a
almond37 [142]

Answer:

5 (for c only)

Step-by-step explanation:

for c:

1st cleaning company: y=17x+15

2nd cleaning company: y=20x

set up as a system of equations. for them to cancle out make the y of one equation negative. I'll be making the second one negative ( it doesn't matter though)

it will look like:

y=17x+15

-y=-20x

make the two equations on top of eachother and line the terms up. Then combine them. The variable "y" will cancle out and you'll be left with

0=-3x+15

then you will add 3x to both sides to get 3x=15 then divide both sides by 3 to get x=5

if you plug in 5 for x into both of the original equations you will see that they will both make $100 in five hours. So you answer is 5

Answer:

The answer is <em>C</em>

Explanation: Given:A security alarm requires a four-digit code. The code can use the digits 0–9 and the digits cannot be repeated.  

there is only 2 numbers which are greater than 7 i.e. 8 and 9. ∴ there is 2 possibility for first place.

For the remaining 3 digits there is 9 possibilities (including 1 which would left after choosing 1 from first place )

No of ways for the alarm code beginning with a number greater than 7= 2 P 1 x 9 P 3

<em>Total ways of code with 4 digits= 10 P 4.</em> Hope this helps :)
