Answer:

a=5

Step-by-step explanation:

You'll want to expand the -4(a-5) first.  That'll be :

-4a+20.  

So 2a-4a+20=10.  

Variables on the left, plain numbers on the right:

2a-4a=10-20

-2a=-10

-a=-5

a=5

Done.

Eddi Din [679]
It doesn't matter what's between it as long as it is within that range, if that makes any sense.

1.25 isn't.
1.75 isn't.
1.83 isn't.

1.625 would be your answer. :)

Use the percent bar model to find the missing percent
Ne4ueva [31]

A percentage is a way to describe a part of a whole. The missing percent on the bar model is equal to 12.5%.

<h3>What are Percentages?</h3>

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

On the percent bar model, above the missing percentage, the fraction is given as 1/8.

Now, the given fraction 1/8 in the form of percentage can be written as,

1/8

= 1/8 × 100%

= 0.125 × 100%

= 12.5%

Hence, the missing percent on the bar model is equal to 12.5%.
