To multiply two fractions:
-- Multiply their numerators; the product is the numerator of the new fraction.
9 x 7 = 63 ; the new fraction is (63) / (something)
-- Multiply their denominators; the product is the denominator of the new fraction.
1 x 10 = 10 ; the new fraction is <em>63/10</em> .
The product of the two original fractions is 63/10 , or <em>6.3</em> .
Answer:
C) Descend 84 feet
Step-by-step explanation:
162+207=369
369-285=84ft above starting point, this means that he must descend 84 feet to reach the starting point.

Step-by-step explanation:
Using it's concept, it is found that the experimental probability that the first vehicle rented today will be a pickup truck is of 0.5 = 50%.
<h3>What is a probability?</h3>
A probability is given by the<u> number of desired outcomes divided by the number of total outcomes</u>. For an experimental probability, these number of outcomes are taken from previous trials.
In this problem, we have that out of 4 vehicles, 2 are pickup trucks, hence the experimental probability is given by:
p = 2/4 = 1/2 = 0.5.

A two digit number has a tens digit and a ones digit.
Let's say x = tens digit and y = ones digit
"The sum of the digits is 5"
x + y = 5
The next phrase is "the number multiplied by 3 is 42" but we need to represent the number using the digits. So they need to be multiplied first by their place value and added together. [Example: 34 = 3(10) + 4(1)]
The number is: 10x + y
3(10x + y) = 42
The system of equations: (two equations for two unknowns)
x + y = 5
30x + 3y = 42
Then you can use substitution or elimination to combine and solve.
I'll use elimination, multiply the entire top equation by -3 and add the equations together. y will cancel out
-3x - 3y = -15
30x + 3y = 42
------------------
27x + 0 = 27
x = 1
then plug x = 1 into either equation to find y
1 + y = 5
y = 4
remember the x and y represent digits so the number xy is 14
