Answer:

The two ratios are equivalent.

Step-by-step explanation:

Reduce both fractions:

6/21 = 2/7  [Take out 3 from both sides]

8/28 = 2/7  [Take out 4 from both sides]

2/7 = 2/7

I WILL GIVE U BRAINLIEST AND THANKS AND 5 STARS
Effectus [21]

Answer:

I agree with Noah's Method because following PEMDAS you have to do exponents first. 10^3 is 1000 and then you can add the 20. Jada's method is incorrect because you cannot add the two together.

A bag contains 25 balls 20 of which are blue what percentage of balls are not blue
Artist 52 [7]

Answer:

20%

Step-by-step explanation:

20/25 = blue

This means 5/25 of the balls in the bag are NOT blue

(25-20 = 5)

We need to convert 5/25 to a percentage

\dfrac{5}{25} = \dfrac{5\times4}{25\times4}=\dfrac{20}{100}

% = per cent

"per" means "out of"

"cent" means "one hundred"

so

20/100 = 20%

Solve for y. -3/y=6 Simplify your answer as much as possible.
Molodets [167]
Solving for "y" means that we need to get y to be on one side of the equation. It should look like y= something. To get the y by itself, we need to get rid of that -3. To do that, we'll have to divide by -3 (because even though there's a y being divided, the -3 is still the numerator). 6/-3 is -1/2. Therefore your answer is y=-1/2
