How to work out math problem %of 50 shirts is 35 shirts
2 answers:
"of' is multiplication.
"is" is equal.
So x% of 50 is 35 could be written as
x%
50 = 35
The first step is to divide by 50 on both sides.
x% times 50 divided by 50 is x%.
35 divided by 50 is .7
So x% = .7.
The next step is to get rid of the percent sign to find the value of x (our answer). To do this, we multiply by 100 on both sides.
x% times 100 is x.
.7 times 100 is 70%.
So x = 70%.
The answer:
70% of 50 shirts is 35 shirts.

Answer:
<h2>If we placed the number 10 in the box, we obtain a system of equations with infinitely many solutions.</h2>Step-by-step explanation:
The given system is
<em>It's important to know that a system with infinitely many solutions, it's a system that has the same equation</em>, that is, both equation represent the same line, or as some textbooks say, one line is on the other one, so they have inifinitely common solutions.
Having said that, the first thing we should do here is reorder the system
This way, you can compare better both equations. If you look closer, observe that the second equation is double, that is, it can be obtained by multiplying a factor of 2 to the first one, that is
So, by multiplying such factor, we obtaine the second equation. Observe that must be equal to 10, that way the system would have infinitely solutions.
Therefore, the answer is 10.
