SORRY if its too late.
Proportions with variables:
let's look at an example from my homework hehe
.3:4=9:y
First, you change the ratios to fractions.
.3/4=9/y.
4 times 9 is 36. I multiplied the numerator of 9/y and the denominator of .3/4.
You also do this with the other numerators and denominators. .3 times y= 36. (Both equations have to equal the same number) if you don't know the answer, just do 36 divided by .3. The answer is 120.
y=120

➪x= 3
Step-by-step explanation:
4x-(8-x)-2=9x-20+x-5
=> 4x-8+x-2 = 9x+x-5
=> 5x-10 = 9x-20+x-5
=> -10+5 = 10x-20-5x
=> -5+20 = 5x
=> 15 =5 x
=> 15/5 = x
=> 3 = x
Answer:
D a reflection over a line through point P followed by a dilation centered at point P
1/3 of an hour is 20mins
multiply 1/2mile*2
and 20mins*2
1mile in 40mins.
1*2.25
40*2.25=90mins
2 1/4 miles in 90mins or an hour and a half
That could also be writen as
2 1/4 miles in 3/2 hours or 1 1/2 hours
