5x+1y=2874
x+y=1246
Im going to use subtraction
5x+y=2874
-x-y=-1246

4x=1628

So now which of the answers also=33?
8+9=17 so no
8+6=14 so no aswell
15+18=33 therefore this is correct. so your answer is c.

Maria studied the traffic trends in India. She found that the number of cars on the roads increases by 10% each year. If there were 80 million cars in year 1 of her study, how many more cars were on the road in year 3 compared to year 2?

Answers

Answer: 8.8 million

Step-by-step explanation:

Given: The number of cars in year 1= 80 million

As she found that the number of cars on the roads increases by 10% each year.

Now, 10% of 80 million= $0.10*80\ million=8\ million$

Thus, the number of cars in year 2= 80 million+8 million=88 million

Now, 10% of 88 million= $0.10*88\ million=8.8\ million$

Thus, the number of cars in year 3= 88 million+8.8 million=96.8 million

Now, the difference in the cars in year 3 compared to year 2=96.8 million-88 million

Thus, the difference in the cars in year 3 compared to year 2=8.8 million

Year 2 is 88 million and in year 3 it is 96.8 million. 96.8 million-88 million it makes 8.8 million. So the answer is 8.8 million people.

Answers

if you divide 42 into groups of 7 then that means that each group would have 5 servers and 2 cooks. so the steps are, you divide 42 by 7 and get 6 (there are 6 groups of 7) so 6*5 would be the number of servers and 6*2 would be the number of cooks. #server = 30 #cooks=12

What is the sum of the two vectors (-1,-4) and (3,5)

Answers

The sum of the vectors is (2,1)

How to find the sum of two vectors?

A vector exists as an object that has both a magnitude and a direction. Geometrically, we can imagine a vector as a directed line segment, whose length exists the magnitude of the vector and with an arrow suggesting the direction. The direction of the vector exists from its tail to its head.

(-1,-4) + (3,5)

( -1+3 , -4+5 )

( 2,1)
