Answer:
D
Step-by-step explanation:
Because it says Klay lunch cost is $2 less than Ella's.
==> Ella's - $2 = Klay's
==> x-2=6
plus both side by 2
so the answer is $8

Answer:
416 (3 s.f.)
Step-by-step explanation:
To multiply decimals, begin by multiplying the numbers as if there is <u>no decimal</u>:
Count the number of digits <u>after</u> the decimal point in each factor:
- 128.5 → 1 digit after the decimal point.
- 3.24 → 2 digits after the decimal point.
Therefore, there is a total of 3 digits after the decimal points.
Put the same number of digits after the decimal point in the product.
Therefore, the solution is to the multiplication is:
The factor with the <u>fewest signification figures</u> is 3.24.
This number has 3 significant figures.
Therefore, the solution to 3 significant figures is:
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 .
