Answer:
Suman 37 km/hr
Narayan 43 km/hr
(extremely sorry if this is wrong!!)
Step-by-step explanation:
We can use the formula distance divided by time is speed.
480/6 = 80.
Their speeds must add up to 80 km/hour
Lets set suman as a variable, lets say s.
Narayan has a speed 6 more than suman so we say 6+s
6+s+s = 80
subtract 6 from both sides
s+s = 74
add like terms
s+s = 2s
2s = 74
divide both sides by 2.
74/2=37
s=37
Suman's speed is 37 km/hr.
Narayan's speed would be 6 more than Suman's so we do 6+37
which makes 43 km/hr

Answer:
<u>The correct answer is </u>
<u>C. k+d=130
</u>
<u>7k = 3d</u>
<u>Number of kids Dr. Irvine see in a week is 39.</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Number of patients Dr. Irvine see in a week = 130
Radio of kids to adults = 3:7 or 3/7
Number of Kids = k
Number of adults = d
2. Let's find the equations system that should be set up to find out how many kids Dr. Irvine see
k + d = 130 (Number of patients Dr. Irvine see in a week)
Including the ratio:
7k = 3d
Replacing d:
d = 130 - k
Now substituting:
7k = 3 * (130 - k)
7k = 390 - 3k
10k = 390
k = 390/10
<u>k = 39</u>
Answer:
3.2 and -0.75
Step-by-step explanation:
5x - 4 > 12
add 4 to the both sides
5x > 12 + 4
5x > 16
divide both sides by 5
x > 16/5
x > 3.2
12x + 5< -4
subtract 5 from both sides
12x < -9
divide both sides by 12
x < -0.75
