Answer:
x = 7, x = -10
Step-by-step explanation:
![x^2+3x-70 = 0](https://tex.z-dn.net/?f=x%5E2%2B3x-70%20%3D%200)
Use the quadratic formula.
![x = \frac{-3 + \sqrt{3^2-4(1)(-70)} }{2(1)} \\x = \frac{-3 - \sqrt{3^2-4(1)(-70)} }{2(1)} \\](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-3%20%2B%20%5Csqrt%7B3%5E2-4%281%29%28-70%29%7D%20%7D%7B2%281%29%7D%20%5C%5Cx%20%3D%20%5Cfrac%7B-3%20-%20%5Csqrt%7B3%5E2-4%281%29%28-70%29%7D%20%7D%7B2%281%29%7D%20%5C%5C)
Solve.
x = 7, x = -10
You can also factor if you want - that is a faster method.
Answer:
x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(x−6)+12=20
(4)(x)+(4)(−6)+12=20(Distribute)
4x+−24+12=20
(4x)+(−24+12)=20(Combine Like Terms)
4x+−12=20
4x−12=20
Step 2: Add 12 to both sides.
4x−12+12=20+12
4x=32
Step 3: Divide both sides by 4.
4x
4
=
32

$4/3=$1.33 per pound.
$9/8 = $1.13 per pound.
The second one is cheaper.
Yes-this is because you can start from the 7th part and then go backwards to forwards to find the letter/number/pattern you need
