x+1 > -5(7-2x)
Use distributive property(Multiply -5 by 7 and -2x).
x+1 > -35 + 10x
Subtract x on both sides so that the variable x is only on one side.
1 > -35 + 9x
Add 35 to both sides so that it cancels out negative 35.
36 > 9x
Divide 9 on both sides so that the only thing remaining on the right side is the variable x.
Final Answer: 4 > x

Maya is packing her backpack for hike. In one pocket, she puts in a 1/2 pound bag of trail mix,a water bottle weighing 2 1/8 pou

Rudik [331]

Total weight of three items is 2.875 pounds

Solution:

Given that,

Maya is packing her backpack for hike

From given,

$pound\ bag\ of\ trail\ mix = \frac{1}{2}\ pounds$

$water\ bottle = 2\frac{1}{8}\ pounds = \frac{17}{8}\ pounds\\\\flashlight = \frac{1}{4}\ pounds$

How much weight do these three items add to her backpack?

Add all these together

$Total\ weight = \frac{1}{2} + \frac{17}{8} + \frac{1}{4}\\\\Total\ weight = \frac{1 \times 4}{2 \times 4} + \frac{17}{8} + \frac{1 \times 2}{4 \times 2}\\\\Total\ weight = \frac{4}{8} + \frac{17}{8} + \frac{2}{8}\\\\Total\ weight = \frac{23}{8} = 2.875$
