The low temperature at 6:45 A. M. was −22°F. At 3:15 P. M. the temperature was 5°F. What was the range of temperature for the day? A −27°F B −17°F C 17°F D 27°F

answer:   2 multiplied by x =24

step-by-step explanation:

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n

y-y1=m(x-x1)

y-1=1(x-8)
