What % of 25 is 21?
​

Answers

Answer 1
Answer:

Answer: 84%

Step-by-step explanation:

1. Since 25 is the output value, we can assume that it is 100%

2. Now we out what we want to find with x

3. From step one, 25=100%

4. In the same line, x%=21

5. This gives us 2 equations:

100%=25(1)

x%=21(2)

6. By dividing equation 1 by equation 2 and taking note of the fact that both the left hand side of both equations have the same unit (%); we have (set up a proportion)

7. Then, take the reciprocal and solve. You should end up with x=84%

Here,
1 mile = 5280 feet,

Multiply both sides by 6,

6 miles = 5280 × 6 feet
6 miles = 31680 feet

What is 10x-3-2x=4?
Please...

Answers

switch the -3 on the other side of = and reduce and simply.

so it would be 8x=7
                       x=7/8
10x-3-2x=4
(Collect like terms)
8x-3=4
(Get x by itself, subtracf 3 from each side)
8x=1
(Divide 1 by 8)
X = 0.125

How to solve 30b=$41.10

Answers

When you're looking for the answer, you simply divide both sides by 30.
30b/30= b
$41.10/30= $1.37
When you've got any answers like this, you always have to try and get b alone, and you may also have to add digits, or divide, it varies from each equation.
Hope this helps :) 
divide both sides by 30 and you'll get the value for b.
