Answer:
Step-by-step explanation:
G=30t+40, C=20t+60, C=G
30t+40=20t+60, subtract 40 from each side
30t=20t+20, subtract 20t from each side
10t=20, divide each side by 10
t=2
So both garages charge the same fot two hours of work.
<span>When converting a number with meters per second to a value with kilometers per second they best way to perform this operation is by using dimensional analysis or the factor label method. You would set up the equation starting with 5120 m/s times 1 km / 1000 m times 3600 s / 1 hr. It would look like this:
(5120 m/ 1 s) x (1 km / 1000 m) x (3600 s / 1 hr)
Your next step would be multiplying all the top numbers (numerators) together 5120 x 1 x 3600 = 18,432,000
Now multiple on the bottom numbers (denominators) together
1 x 1000 x 1 = 1000
Now you can divide the top product by the bottom product. 18,432,000 / 1000 = 18,432 km/hr is your final answer.</span>
Given : m represents the number of men at the club
It means - Total number of men at the club are : m
Given : There are four more women than men at the club
It means - Total number of women at the club are 4 more than men
Total number of women at the club are : m + 4
Total number of men and women at the club are :
Total number of men + Total number of women
m + (m + 4)
m + m + 4
4 + 2m
