Answer:
-17/18
Step-by-step explanation:
find least common multiple, which is 18
multiply the numerators by the number you multiplied on the denominator.
and subtract.
The unit rate is 9 miles per hour.
In order to find how much its unit rate will be you need to use this expression below.
<em>n = number of hours</em>
<em>m = number of miles </em>
m divided by n or <em>m/n</em>
In order to find how much does he travel in given hours see this below.
<em>n = number of hours</em>
<em>m = number of miles for 1 hour</em>
<em>nm or n * m</em>
Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same denominator, like this: Find the smallest multiple (LCM) of both numbers. Rewrite the fractions as equivalent fractions with the LCM as the denominator.
Answer:
60
Step-by-step explanation:
The shaded region's area is the difference between the area of the outer rectangle and the white rectangle.
area = LW - lw
area = (4 + 4)(9 + 3) - (4)(9)
area = (8)(12) - 36
area = 96 - 36
area = 60
