C. 5.54 years
Explanation: took the test
Answer:
d
Step-by-step explanation:
<span>400 - 2*Age = 244 <<
-2 * Age = -156
So our age = 78 years, months, days, hours since there were no actual units supplied.
</span><span>400 - 2x = 244
-2x = 244 - 400
-2x = -156
x = -156/-2
A better example above as above was just a simplified version.</span>
Find the ratio of two corresponding sides,
- if you start with the smaller figure, your answer will be less than one
- if you start with the larger figure, your answer will be greater than one
the amount of time of the two trips is a proportional relationship
<h3>What is proportional relationship?</h3>
mathematical expressions are said to be proportional if there unit rate are equal. this means that the expressions will give similar results when similar values are substituted into the equation.
<u>solution:</u>
Driving 7 hrs within 385 miles represents a unit rate of 385 / 7 = 55 miles per hour or 55 mph
while 3 hrs in 165 miles represents a unit rate of 165 / 3 = 55 mph
since both situations gave similar speed in miles per hour they are said to have a proportional relationship.
