1. -5x - 6 = 1<br> 2. 12d + 2 - 3d = 5<br> 3. 0.25x + 7 = 12<br> 4. 7.4p - 9.2p = -2.6 + 5.3

1.
-5x - 6 = 1
-5x = 7
x = 7/-5

2.
12d + 2 - 3d = 5
9d + 2 = 5
9d = 3
d = 1/3

3.
0.25x + 7 = 12
0.25x = 5
x = 20

4.
7.4p - 9.2p = -2.6 + 5.3
-1.8p = 2.7
p = -1.5

Hope this helps! :)

16 3/4 hours in two days plan to work 12 3/4 hour the next two days. How many hours will u total on your time sheet for these 4

sergiy2304 [10]

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

$\bf \stackrel{mixed}{16\frac{3}{4}}\implies \cfrac{16\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{67}{4}}~\hfill \stackrel{mixed}{12\frac{3}{4}}\implies \cfrac{12\cdot 4+3}{4}\implies \cfrac{47}{4} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{all 4 days summed up}}{\cfrac{67}{4}+\cfrac{47}{4}}\implies \cfrac{67+47}{4}\implies \cfrac{114}{4}\implies \cfrac{57}{2}\implies 28\frac{1}{2}$
