The value of n is 11.
<u>Step-by-step explanation</u>:
The given expression is (n-9) ÷ 10 = -2
<u>To find the value of n</u> :
- From the expression, it is determined that (n-9) is the numerator and 10 is the denominator.
- Cross multiply the denominator in the left side of the expression to the another side.
The expression becomes (n-9) = (10
-2).
⇒ n-9 = -20
Keep the n term on one side and the constants on other side.
⇒ n = -20+9
⇒ n = -11
Therefore, the value of n is 11.
Let X be the variable used to represent the expression of the total number of books that Mario has read.
We used 4X to represent "four times the number of books". Then we add -2 to interpret the words "for two less than".
Therefore, we have an expression of 4X-2 for the total number of books that Mario has read.
Answer:
25%
Step-by-step explanation:
1. 4.75/19 = .25
2. .25 = 25%
Answer:3/2
how i did this
Add 11 to both sides.
4x=5+1
Simplify 5+15+1 to 66.
4x=6
Divide both sides by 4
x= 6/4
Simplify 6/4 to 3/2
Awnser
x=3/2
Sorry if not helpful just trying my best :)
