Answer:
The average salary of master's degree people is $ 63,000 And
The average salary of bachelor's degree people is $ 52,000
Step-by-step explanation:
Given in question as :
Let the average salary of master's degree people = $ M And
Let the average salary of bachelor's degree people = $ B
According to question ,
The average salary of master's degree people + The average salary of bachelor's degree people = $115,000
Or , $ M + $ B = $ 115,000 ............. A
Again ,
$ M = 2 × $ B - $ 41,000 ............... B
From eq A and eq B
(2 × $ B - $ 41,000 ) + ( $ B ) = $ 115,000
Or, 3×$ B = 156,000
∴ B = = $ 52,000
And M = $ 115,000 - $ 52,000
∴ M = $ 63,000
Hence The average salary of master's degree people is $ 63,000 And
The average salary of bachelor's degree people is $ 52,000 Answer
Answer is (1) 160 km in 2 hours and
(2) 16 miles in 12 minutes.
Step by step.
80 km / 1 hour = x km /2 hours
Cross multiply =
x = 160
The second one requires a little more math. Because we are looking at how far in minutes, we change the rate of 80km in 1 hour to 80 km in 60 minutes.
80 km / 60 = x / 12
Cross multiply
12x = 960
Solve for x by dividing both sides by 12
X = 16
I did the math on a print screen to explain the cross multiply.
