Answer:

1. -2, 2. -23, 3. 25

Step-by-step explanation:

1. -2+5x8/-12=  step 1: add -2+5

-2+5=3       step 2: 3(8)

3x8= 24     step 3: 24/-12

24/-12= -2

2. -2(9-4)+3=?  step 1: combine like terms -2(9) and -2(-4)

-18-8+3=?    step 2: combine like terms

-26+3=?      step 3: combine like terms

-23=?

3. 2x + 130=180    step 1: -130 on both sides

   2x = 50              step 2: /2 on both sides

    x = 25

8. Hassan made a vegetable salad with 2 3/8 pounds
amm1812

let's convert firstly the mixed fractions to improper fractions and then add up.

\bf \stackrel{mixed}{2\frac{3}{8}}\implies \cfrac{2\cdot 8+3}{8}\implies \stackrel{improper}{\cfrac{19}{8}}~\hfill \stackrel{mixed}{1\frac{1}{4}}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}} \\\\\\ \stackrel{mixed}{2\frac{7}{8}}\implies \cfrac{2\cdot 8+7}{8}\implies \stackrel{improper}{\cfrac{23}{8}} \\\\[-0.35em] ~\dotfill

\bf \cfrac{19}{8}+\cfrac{5}{4}+\cfrac{23}{8}\implies \stackrel{\textit{using an LCD of 8}}{\implies \cfrac{(1)19+(2)5+(1)23}{8}}\implies \cfrac{19+10+23}{8} \\\\\\ \cfrac{52}{8}\implies \cfrac{13}{2}\implies 6\frac{1}{2}
