Answer:
9(5e-3f)
Step-by-step explanation:
so, to start, you want to see what they have in common. the variables are not the same, so you cannot take a variable out; however, 45 and 27 have something in common. they can both be divided by 9! (this is a skill you will have to practice). so, after recognizing this, you can divide both numbers by 9, and you would have 5e-3f. however, we cannot just change that because that is not equal to 45e-27f. so, we make sure we include what we did. because we divided by nine, we are going to put the greatest common factor outside of the numbers after we put them in parentheses. 9(5e-3f). we do this because multiplication is the opposite of division, and so this just shows that if we use the distributive property, it would multiply back out to 45e-27f. I hope this helps!

Answer:
1 :2
Step-by-step explanation:
12 are yellow, 4 are pink
To find the number of red
24 -12 -4 = 8
There are 8 red balls
We want the ratio of
red: yellow or pink
8 : 12+4
8 :16
Divide each side by 8
8/8 : 16/8
1 :2
Answer:
-7
Step-by-step explanation:
4-2x+6=24
10-2x=24
-2x=24-10
-2x=14
X=-7
You need the starting point and the end point and count how long it took to get to one point to the either
