Mathematics

Vaselesa [24]3 years ago
5 0

Answer:

6 and 7

Step-by-step explanation:

x + y = 13

xy = 42

I just listed the two equations out and the answer just popped out. The trick to this is just thinking about two numbers that obviously both below 13 that add up to it.  6 and 7 is the solution.

72 is what percent of 45?<br><br> __ = p/100<br><br> p= __
Marta_Voda [28]

Answer:

72 of 45 is 160%

Step-by-step explanation:

72 of 45 can be written as:

\frac{72}{45}

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

\frac{72}{45} *\frac{100}{100}

=(\frac{72*100}{45} )*\frac{1}{100} =\frac{160}{100}

Therefore, the answer is 160%

If you are using a calculator, simply enter 72÷45×100 which will give you 160 as the answer.

2) 7+8=15   This would be a single line, not a triangle.

3) 3+8<15   This would be a single line, not a triangle.

2) 15+8=23   This would be a single line, not a triangle.
