zavuch27 [327]

Answer:

\frac{13}{20}

Step-by-step explanation:

\frac{1}{4}  +  \frac{2}{5}

First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.

\frac{ 1 \times 5}{4 \times 5}  +  \frac{2 \times 4}{5 \times 4}

\frac{5}{20}  +  \frac{8}{20}

=  \frac{13}{20}

demoninator now doesn't change unless you're multiplying or dividing.

marysya [2.9K]

Answer:

Step-by-step explanation:

Let's solve the given system of linear equations:

a+b = 13

0.750 + 1.15b = 12.55

Let's eliminate b.  To do this, solve the first equation for b, obtaining b = 13 - a, and then substitute 13 - a for b in the second equation:

0.750 + 1.15(13 - a) = 12.55.  

Next, subtract 0.750 from both sides, obtaining:  1.15(13 - a) = 11.8

Dividing both sides by 1.15 yields 13 - a = 10.26

Then a = 13 - 10.26, or a = 2.74.  

Since a + b = 13, b = 13 - 2.74, or 10.26

This person bought 2.74 pounds of apples and 10.26 pounds of bananas.
