1 answer:

4 0

Well first you substitute -3 for y and then subtract 12 from both sides of the equation and it should look like -15=-3x. Then divide 3 on both sides and you should end up getting 5=x.

2 3/4+3 5/8 simplified

otez555 [7]

$2\frac{3}{4}+3 \frac{5}{8}=6\frac{3}{8}$

Solution:

Given expression is $2\frac{3}{4}+3 \frac{5}{8}$ .

To simplify the expression $2\frac{3}{4}+3 \frac{5}{8}.$

Let us first convert the mixed fraction into improper fraction.

$2\frac{3}{4}+3 \frac{5}{8}=\frac{(2\times 4) + 3}{4}+ \frac{(3 \times 8)+5}{8}$

$=\frac{8+ 3}{4}+ \frac{24+5}{8}$

$=\frac{11}{4}+ \frac{29}{8}$

Take LCM for the denominators (LCM of 4, 8 = 8) and make the same.

$=\frac{11\times2}{4\times 2}+ \frac{29\times1}{8\times1}$

$=\frac{22}{8}+ \frac{29}{8}$

$=\frac{51}{8}$

Now, divide 51 by 8 and again write it in the mixed fraction.

$=6\frac{3}{8}$

$2\frac{3}{4}+3 \frac{5}{8}=6\frac{3}{8}$

Hence, the simplified answer is $6\frac{3}{8}$ .
