Answer:
the actual distance is 1800 ft.
Step-by-step explanation:
Proportion states that the two fractions or ratios are equal.
Let x be the actual distance.
As per the statement:
Reggie was looking at a map of the school the scale shows that 1 inch equals 150 ft.
⇒1 inch = 150 ft.
if the distance between his classroom in the cafeteria measures 12 in on the map.
by definition of proportions we have;

By cross multiply we have;
ft
Therefore, the actual distance is 1800 ft.
The equation would look like
Y=-4x+7
Y=mx+b
Answer:
C - 45 is the LCM of 15 & 45
Step-by-step explanation:
Find the multiples:
15, 30, 45, 60
45, 90
They both have 45 in common
1650 - 1200 = 450
What percent is 450 of 1200?
y = 450/1200
y = 0.375
37.5% increase
(x^2-3x+2)-1(3x^2-5x-1)=
x^2-3x+2-3x^2+5x+1=
x^2-3x^2-3x+5x+2+1=
-2x^2+2x+3
