City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city awas 8' c more than three times the temperature of city b. the temperature of city a minus twice the
temperature of city b was-3' c. the following system of equations models this scenario
4x = 8 + 3y
x-2y=-3
what was the temperature of city a and city b on that day?
city a was 'c. and city b was 4°c
city a was 3* c, and city b was -1°c.
city a was c, and city byvas -3°c
city awas 5 c and city b was -5°c

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
