Ratio of A to B is 7:5...

so if there was 295 mL of compound B...
7 / 5 = a / 295
cross multiply
(5)(a) = (295)(7)
5a = 2065
a = 2065/5
a = 413 .... so 413 mL of compound A would be used

for a total solution of (295 + 413) = 708 mL solution <===

Three more than 8 times a number is 29. Find the number.
yanalaym [24]
Well, first off, to solve for this, we can write the expression and then solve from there.
Expression: 8x + 3 = 29
So, now that we have our expression, we can solve for our missing number using the balancing method.
8x + 3 = 29
8x + 3 - 3 = 29 - 3 (we subtracted the three because we needed to get rid of the three on the left side of the equation do now we are just left with 8x = 26.
8x = 26
8x/8 = 26/8. (So, the 8 on the left side cancels out and we are just left with X.
X = 26/8
X = 13/4
X = 3 and 1/4
So, in conclusion, the answer to this question is: X = 3 and 1/4 as a mixed number or 13/4 as an improper fraction.
Glad I could help!

Which equation shows 4n = 2(+ - 3) solved for T?
Ghella [55]

Answer:

C. T = 4n+6/2

Step-by-step explanation:

4n = 2(T-3)

or, 4n = 2T-6

or, 4n + 6 = 2T

or, 4n + 6 / 2 = T

or, T = 4n + 6 / 2
