The total amount of Maureen savings is $ 69
<em><u>Solution:</u></em>
Given that Maureen spent $ 48 on books. That is 70 % of her savings
To find: Total amount of Maureen savings
From given statement, 70 % of her savings is spent on books
Let "x" be the total amount of Maureen savings
Therefore,
70 % of total amount = $ 48
70 % of x = 48
Here "of" represents multiplication or product
Thus total amount of Maureen savings is $ 69
Answer:
The correct answer is x = -6.
Step-by-step explanation:
To solve this problem, we first must use the distributive property on the right side of the equation. This means that we can take the coefficient (the number located on the outside of the parentheses) and multiply it by the terms inside the parentheses. If performed correctly, we get the following:
-20 = -2(4 -x)
-20 = -2(4) - (-2)(x)
-20 = -8 + 2x
Next, we must begin to isolate the variable x on the right side of the equation. To do this, we should begin by adding 8 to both sides to cancel out the -8 on the right side of the equation.
-20 + 8 = -8 + 8 + 2x
-12 = 2x
Finally, we should divide both sides by 2 to get rid of the coefficient of x on the right side of the equation.
-12/2 = 2x/2
x = -6
Therefore, your answer is x = -6.
To check this answer, you could substitute this value back into the original equation and make sure that it produces a true statement.
Hope this helps!

i think it's:
Step-by-step explanation:
x=-2
there are 6 1/6 per hour
multiply 1/3 by 6
1/3 * 6 = 6/3 = 2 miles per hour
V=hpir²
1/2 full
Vcylinderthisone=(1/2)hpir^2
given
h=250
r=100
so
V=(1/2)(250)pi(100)²
V=125pi10000
V=1250000pi
aprox pi=3.141592
V=3926990 cm^3
divide by 1000
3926.99 liters
about 3927 liters
