Set up an equation:
0.75x = 18
Divide both sides by 0.75:
x = 18/0.75
x = 24
Answer: 24
Answer:
18.027756
Step-by-step explanation:
Pythagorean Theorem
10²+15²=c²
100+225=c²
325=c²
√325=c
c=18.027756
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, and in this case:
-m/4=-1
-m=-4
m=4, so the slope of the perpendicular line is 4 so we have thus far:
y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"
3=4(-4)+b
3=-16+b
19=b, so our line is:
y=4x+19
Answer:
2(2x+5) (x+1) = 2(x+1)(2x+5)
Step-by-step explanation:
4x^2 +14x+10
Factor out the 2
2(2x^2 +7x+5)
2(2x+5) (x+1)
You need to keep the 2 that you factored out
2(2x+5) (x+1) = 2(x+1)(2x+5) by the Commutative Property of Multiplication
Answer: 2.4 miles per hour
Step-by-step explanation: just do 7.2/3=2.4
or another way you could do this is do 2.4 x 3=7.2
