Answer:
Step-by-step explanation:
there are two ways to solve systems of equations, elimination or substitution, this looks like elimination would work quickly
x= 25 -y
x + y = 25 (eq 1)
5x + y = 10 (eq 2)
subtract 2 from 1
x + y = 25
-(5x + y = 10)
-4x + 0y = 15
-4x = 15
x = - 15/4
now plug in x into either starting equations and solve for y
-15/4 + y = 25
y = 25 + 15/4
y = 100/4 + 15 /4
y = 115 /4
y = 28 3/4
we have solved it :)

Step-by-step explanation:
untill you increase the points. This is the most i can do to help.
The formula to find the volume of a rectangular prism is: l x w x h.
5 x 6.75 = 33.75 33.75 x 3.5 = 118.125
Your answer is: V = 118.125 m³
Answer:
80 miles
Step-by-step explanation:
40 miles per hour means you move 40 miles in one hour.
If it took 2 hours to travel between the two towns at 40 mph, multiply 40 by 2 and you get 80.
Hope this helps!
