1/3 times 1/5
You have one third of a section of 1/5.
The variable y is given.
now, substitute y in the second equation to get
-4x - (-4x-7) = 7
then we solve
first distribute
-4x+4x+7=7
combine like terms
0+7 = 7
7 = 7
because the answer is true, the solution to this system is “all real numbers”
Equation can be used to find x is 60/55 + 60+x = 2.75
The time of going to rink is 2.75
We know,
speed = distance/time
⇒ Time = distance / speed
<h3>How to solve?</h3>
(1) Way to rink
Given :
Distance = 60 miles
Speed = 55 miles per hours,
⇒ Time taken by him = Distance / speed = 60/55 hours
(2) Way to home
Given : Distance = 60 miles
Let Speed be x,
⇒ Time taken by him = distance/speed = 60/x hours
Total time taken = 60/55 + 60+x
According to Question, Total time = 2.75 hours,
Thus, 60/55 + 60+x = 2.75 is the required equation.

Answer:
No
Step-by-step explanation:
10/18 does not equal 45/18
An example of a proportional number is:
4/5 and 8/10
Both numbers are multiplied by 2 making them proportional
10/18 and 45/18 are not proportional
Hope this helped :)
Answer:
y+2=3(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(7-(-2))/(2-(-1))
m=(7+2)/(2+1)
m=9/3
m=3
y-(-2)=3(x-(-1))
y+2=3(x+1)
