Do you have an iea of what do to before i give you the answer?
So you would do 41.7g - 20.2g and get 21.5g, then multiply it by 140g. 140g x 21.5g = 3010g
Answer is A. 18
EXPLANATION-
Its Simplifying
(9x + -44) = (6x + 10)
Reorder the terms:
(-44 + 9x) = (6x + 10)
Remove parenthesis around (-44 + 9x)
-44 + 9x = (6x + 10)
Reorder the terms:
-44 + 9x = (10 + 6x)
Remove parenthesis around (10 + 6x)
-44 + 9x = 10 + 6x
Solving
-44 + 9x = 10 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
-44 + 9x + -6x = 10 + 6x + -6x
Combine like terms: 9x + -6x = 3x
-44 + 3x = 10 + 6x + -6x
Combine like terms: 6x + -6x = 0
-44 + 3x = 10 + 0
-44 + 3x = 10
Add '44' to each side of the equation.
-44 + 44 + 3x = 10 + 44
Combine like terms: -44 + 44 = 0
0 + 3x = 10 + 44
3x = 10 + 44
Combine like terms: 10 + 44 = 54
3x = 54
Divide each side by '3'.
x = 18
Simplifying
x = 18
Answer: b = 10
Step-by-step explanation:
We want a ratio of b/2 that is equal to the ratio of 1/4 to 1 1/4 (or 5/4).
Ratio of (1/4)/(5/4):
(1/4)/(5/4) = (1/4)*(4/5) = 4/20 = 1/5 or 0.2
We want 2/b = 1/5 or 0.20
2/b = 0.20
b = 2/0.20
b = 10
--
Check: Does 10/2 = (1/4)/(5/4)?
Yes
b is 10
