$76.5
51/6 = 8.5
8.5 x 9 = 76.5
Answer:
2248
Step-by-step explanation:
Take the amount earned weekly and multiply by 4 weeks
562*4
2248
49x^2 = 36
take square roots of both sides:-
7x = +/- 6
x = 6/7, -6/7.
Answer:
1. C
2. B
3. B
Step-by-step explanation:
Vertical angles are the angles opposite each other when two lines cross, thus angles with measures (x+77)° and 126° are vertical angles.
Vertical angles are congruent.
Hence,
The answer would be about 89%
to solve this problem first you would have to subtract 4 from 36 to get 32 because you want to know how many she got right first .
so you put 32 over 36 ( the number she got right over the total number of questions ) and n ( the number you don't know yet ) over 100 . that will be the percent .
next all you have to do is cross multiply 32 times 100 and 36n , to get 3200 and 36n .
now you have to divide 3200=36n by 36 so you get n by its self but you have to divide on both sides of the equal sign .
when you divide you will then get 88 with a lot of remainder 8's so you would just round up to 89 .
finally you know n = 89% so she got 89% of her questions right .
