Answer:

a=22,\\b=31,\\c=13

Step-by-step explanation:

When choosing equations to write, make sure you choose a pair that allow you to isolate a variable and solve for it.

Sample solution:

a+25+28=16+25+34,\\\\a+28=16+34,\\a+28=50,\\a=\boxed{22}

16+b+28=16+25+34,\\b+44=75,\\b=\boxed{31}

34+c+28=16+25+34,\\c+28=41,\\c=\boxed{13}

FIRST PERSON WHO ANSWERS THIS WILL BE BRAINLIEST
djverab [1.8K]

Answer:

2.- 100

Step-by-step explanation 1:

\frac{7}{25} + \frac{3}{4} = \frac{28}{100} + \frac{75}{100} = \frac{103}{100}

↑ As we can see, the only common multiple between 4 and 25 that is given to is 100.

Step-by-step explanation 2:

\frac{(7 * 4) + (3 * 25)}{4 * 25} = \frac{28 * 75}{100} = \frac{103}{100}

↑ Another way of knowing the answer is by using a fraction solving method. As we can see, the denominator is once again 100.

Hope it helped,
