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

2x+2y = 4 2x + 2y = 3 One Solution No Solutions Infinitely Many Solutions
Arlecino [84]

The system has no solutions

Here, we want to solve the system of linear equations

As we can see, the exact expression is what we have on the left side of both equations

The only different thing is what we have on the right hand side

What this mean is that no values of x and y can satisfy both equations

With that in mind, we have it that the system of equations has no solutions

Answer this question showing work. 2b − 7 ≥− 14 + 2b
jeka94

Answer:

No solution

Step-by-step explanation:

This answer has no solution, follow these steps to see how.

First, you add 7 on both sides.

Then you should have 2b > -7 +2b

You see how there is a 2b on both sides? this makes the problem unsolvable.

Say you were to continue though. You would subtract 2b on both sides and end up getting 0 > -7.  Therefore there is no solution.
