40 because you would divide the miles by hours to find the rate of change.
120/3= 40
for each inch is 5 feet, so for each 0.5 aka 1/2 inch, it would be 2.5 inches
2in: 5+5=10ft
2.5in: 5+5+2.5=12.5ft
or just simply mutiply by 2
2(5)= 10ft
2.5 inches so 2.5(5)=12.5
The dimensions of the actual room are 10 feet by 12.5 feet
Answer:
y=8.94
Step-by-step explanation:
use the formula: a^2+b^2=c^2
64+y^2=144
y=
or y=8.94
Answer:
y= 1 and x=-2
Step-by-step explanation:
Since they both equal y, you can equal them to each other:
x + 3 = 2x + 5
Then solve:
x - x + 3 = 2x - x + 5
3 - 5 = x + 5 - 5
-2 = x
Substitute x in either equation to solve for y:
y = (-2) +3
y = 1
Or the other equation:
y = 2(-2) + 5
y = -4 + 5
y = 1
hope this helps :)
