400 = 8b + y (subtract 8b from each side)
<u>-8b -8b </u>
400 - 8b = y
The answer is y = -8b + 400
i isolated y, which means i left it alone on one side of the equation
Answer:
From least to greatest
23* 1/4, 23* 2/2, 23* 13/5
Explanation
In order to do this without multiplication, place the fractions in ascending order.
The denominators of these fractions have 20 as a common multiple.
2/2 • 10 = 20/20
1/4 • 5 = 5/20
13/5 • 4 = 52/20
From this it logically follows that the fractions in ascending order are:
1/4, 2/2, 13/5
Therefore the products in ascending order are:
23* 1/4, 23* 2/2, 23* 13/5
I gotchu bro. First you want to expand 5 x 10^-6 which is (HINT: 10... and then move the decimal 6 to the LEFT) so: 0.000010 (you can drop the 0 after the 1)
So then, Take 0.04 and divide 0.00001 to get your answer.
(U got a test so im not gonna answer it for u. U got this)
