First you subtract (1/4) from each side to get C by itself, then you convert (4/4) into 1. Then you divide both sides by (-4) to get C to equal 1. So your final answer is C=-1/4
Answer:
Assuming you mean 2+ (4/5), no
Step-by-step explanation:
=2* (5/5) + (4/5)
=10/5 + 4/5
=14/5
if you mean (2+4)/5,
its 6/5, so still not 1/3
Answer:
$ 12.6 / h
Step-by-step explanation:
5% of 12 = 0.05 * 12 = 0.6
Now adding it to the amount he makes, since it is a raise:
0.6 + 12 = 12.6 $ / h
Another (and faster) way to calculate it:
1.05 * 12 = 12.6
It is negative.
When you subtract a negative a positive number from a negative number, the result is positive. The equation can be rewritten as -8.8-(+3.4).
At the start of 2nd day, he completed 4 chairs....at the end of the day, (9 hrs later) he completed 7 chairs....that means he had completed (7-4) = 3 chairs in 9 hrs. 9/3 = 3...that means it takes 3 hrs to complete 1 chair.
He has 7....so he needs 3 more chairs...and if 1 chair takes 3 hrs, then 3 chairs takes (3 * 3) = 9 hrs <===
