1. a=c

2. (b)/(a) = (c)/(b)

3. b-a=c-b

4. a
5. if a=b, then b=c

I think #2 is correct ,but I don't know about the others

Answer 1
Answer:

Options 2 and 5 i.e., (b)/(a)=(c)/(b) and b=c are the correct statements such that (a)/(b)=(b)/(c).

Ratio

Ratio is the mathematical indication that tells how many times one number contains another.

How to simplify the ratios?

Reciprocate the given proportion both sides-

(b)/(a)=(c)/(b)

So, option 2 is correct.

Now, if a=b then, the proportion will become-

1=(b)/(c)\nb=c

So, option 5 is correct.

Thus, options 2 and 5 are the correct statements.

Answer 2
Answer: a : b
b : c

Imagine if the ratio is as follows :
3 : 6
6 : 12

Yes, only number 2 is correct.

Your number 4 seems to only consist of a. Hence, I can't make any assumptions based on that.

So yes, only number 2 is correct.

Hope this helps. - M

How to divide 4.50 by 18.00

Answers

Data:

price($)__ gallons
x -------------- 1
18.00 ------------ 4.5

Solving: Rule of three (directly proportional)
(x)/(18.00) = (1)/(4.5)
multiply cross
4.5*x = 18.00*1
4.5x = 18.00
x = (18.00)/(4.5)
\boxed{\boxed{x = \$\:4.00}}\end{array}}\qquad\quad\checkmark

The solution to 4x + 7 - 9 = -14 is

Answers

Hello!

We will solve this below.

First we add 9 to both sides.

4x+7=-5

Subtract 7 from both sides

4x=-12

Finally, we divide both sides by 4.

x= -3

I hope this helps!

-3

WORK:

4x +7 - 9 = -14

4x + (-2) = -14

4x - 2 = -14

4x = -14+2

4x = -12

x=-12/4

x= -3
