What percent of 48 is 12 please show work
iVinArrow [24]

25 % of 48 is 12

<em><u>Solution:</u></em>

Given that we have to find what percent of 48 is 12

Let "x" be the required percent

From given statement,

what percent of 48 is 12

Let us say,

x percent of 48 is 12

Writing it mathematically we get,

x % of 48 is 12

Evaluate the above expression to find "x"

x \% \text{ of } 48 = 12\\\\x \% \times 48 = 12\\\\\frac{x}{100} \times 48 = 12\\\\x = \frac{12 \times 100}{48}\\\\x = \frac{1200}{48} = 25

Thus 25 % of 48 is 12

Use rounding or compatible numbers to estimate the difference 359-224
tiny-mole [99]
359 goes to 360
224 goes to 220
360-220=140
I moved the answer up one then down four the way I moved the original numbers, so 140 is actually down three of the actual answer which must be 143 then

I dont know how to solve these
Ne4ueva [31]

Answer:

137°

Step-by-step explanation:

So, both are equal to each other due to them being the same degree angle.

5x+7=8x-71

subtract 5x on both sides

7=3x-71

add 71 to both sides

77=3x

divide both sides by 3

77/3=x

x equals about 26

insert x into the problems

[5(26)+7]°

this equals 137°

[8(26)-71]°

this equals 137°
