To figure this out, you have to figure out what Donovan scored.
Just divide his score (39 ÷ 50) and get 0.78.
Since we already knew this, we can figure out Marci's score. Since she score 88%, we can assume she scored somewhere in the 40's.
Once you figure out what her score was out of 50, divide it.
Your equation should look like this: 44 ÷ 50 = 0.88
This means that Marci answered 44 questions out of 50 questions correctly. (44/50)
Answer: Each sister got 8 candles
How?
(2/7)(56) = 16
16/2 = 8
So, add 34+68+14+19 to equal 135. Then divide by 9 to equal 15.
If you write out the numbers, the E. Coli is 0.0000005 m wide while a hair is 0.000017. Less zeros after the decimal mean it is a larger number because it is closer to 1. So, a human hair is wider.
This equation is not correct. Because,
![4x+2(x+3)\quad =\quad 4x+2\cdot x+2\cdot 3=4x+2x+6=\quad 6x+6](https://tex.z-dn.net/?f=4x%2B2%28x%2B3%29%5Cquad%20%3D%5Cquad%204x%2B2%5Ccdot%20x%2B2%5Ccdot%203%3D4x%2B2x%2B6%3D%5Cquad%206x%2B6)
And
![6x+6\quad \neq \quad 8x+6](https://tex.z-dn.net/?f=6x%2B6%5Cquad%20%5Cneq%20%5Cquad%208x%2B6)
The only possible, solution for this equation would be, x=0. Because,
for x=0 :
