Answer:
n=4
Step-by-step explanation:
First use distributive property to expand -10(n-2)
-5n-20=-20-10n+20
Simplify
-5n-20=-10n
Combine Like Terms
-20=-5n
Divide both sides by -5 to isolate "n"
n=4
Answer:
Slope <em>m</em> = 3/2
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define Equation</u>
3x - 2y - 6 = 0
<u>Step 2: Rewrite</u>
<em>Find slope-intercept form</em>
- Subtract 3x on both sides: -2y - 6 = -3x
- Add 6 on both sides: -2y = -3x + 6
- Divide -2 on both sides: y = 3/2x - 3
<u>Step 3: Break Function</u>
<em>Identify Parts.</em>
Slope <em>m</em> = 3/2
y-intercept <em>b</em> = -3
Answer:
55
Step-by-step explanation:
Answer:
35 pounds of tea for 80 cents.
Step-by-step explanation:
Equation::
value + value = value
80x + 60(50-x) = 74*50
80x + 60*50 - 60x = 74*50
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
