Answer:
Step-by-step explanation:
2-(-1\8)±-7\4 then
2 plus 1\8 plus -7\4
2 plus 1\8 plus -14\8
2 -13\8
2= 16/8
3\8?
Answer:
20
Step-by-step explanation:
set a proportion
16 x
____ = ______
80 100
by doing this you can cross multiply the terms
80x=1600
divide both sides by 80
x=1600/ 80=20
1.y= 3x+ 19
2. y= 4x+10
3. y= 7x+-5
The standard form:

---------------------------------------
<em>use distributive property</em>
<em>multiply both sides by 8</em>

<em>add 2x to both sides</em>
<em>add 8 to both sides</em>
