X=-4 you have to substitue first so you put the equation where the X is and then you would distribute and then add the numbers that have the common exponent
Answer:
-1/5
Step-by-step explanation:
When a line is perpendicular to another line, it's gradient will be a reciprocal.
To calculate the reciprocal of a number you have to flip the fraction the other way around.
So, in the case our current gradient is 5/1 (5/1 is the same as just 5) and we need to flip in over to get 1/5, which is our new gradient.
The final step is to make the number negative because the line is going down. This gives us the final answer of -1/5.
Ew, mental math... so basically, we would estimate the washing dishes to 20 minutes, and cleaning 40 min,
together 20+40 min
is 60 minutes, aprox 1 hour
Shelly spent almost 1 hour cleaning
He writes a check so he takes out the money so 2340 - 140 and then he deposits so because 2340 - 140 = 2,200 so, when he deposits 2200 + 268 then it will be the answer $2468.
$2468
I had this question yesterday or the other day so yeah hope this helps! ^^
