Answer:
n<2
Step-by-step explanation:
6.2n<2n+8.4
Move variable to the left hand side and change its sign
6.2n - 2n < 8.4
Combine like terms
4.2n < 8.4
divide both side by 4.2
n < 2
Quincy bought a keyboard priced at $178.30. The sales tax was found by multiplying the price of the keyboard by 0.08. What was the total cost of the keyboard with sales tax?
Answer:
$192.56
Step-by-step explanation:
The keyboard is priced at 1($178.30).
The sales tax is 0.08($178.30) = $14.26
The total cost is thus $178.30 + $14.27 = $192.56
A more efficient way to calculate this would be as follows:
Total cost = 1.08($178.30) = $192.56

What is the value of the equation -2/3x + 9 = 4/3 x -3?
Answer:
x = 6
Step-by-step explanation:
[tex]\frac{-2}{3}x+9=\frac{4}{3}x-3\\\\\frac{-2}{3}x-\frac{4}{3}=-3-9\\\\\frac{-2-4}{3}x= - 12\\\\\frac{-6}{3}x = -12\\\\ -2x -12\\\\x = \frac{-12}{-2}\\\\x = 6[/tex]

A store sells mugs. Each mug costs the same amount. During a sale, the store reduces the price of each mug by $1.75. Wen spends $28.20 on 5 mugs at the sale price. What was the price of 1 mug before the sale?
Answer:
$7.39Step-by-step explanation:
Let the initial price be x
Then the reduced price is
x - 1.75If 5 mugs cost $28.20, we have equation:
(x - 1.75)*5 = 28.20x - 1.75 = 28.20/5x - 1.75 = 5.64x = 1.75 + 5.64x = 7.39Initial price for 1 mug was $7.39
Answer:
so the price for 1 mug was $7.39
Step-by-step explanation:
initial price will be P
Then the lower price is
x - 1.75
If 5 mugs cost $28.20 then we have to write an equation in order to find the price for 1 mug.
(P - 1.75)*5 = 28.20
P - 1.75 = 28.20/5
P - 1.75 = 5.64
P = 1.75 + 5.64
P = 7.39
Initial price for 1 mug was $7.39

Answer:
y = -2x + 1
Step-by-step explanation:
y = mx + b (m is the slope and b is the y-intercept)
y = mx + 1
Equation for slope: [tex]\frac{y1-y2}{x1-x2}[/tex]
(0,1) (1,-1)
[tex]\frac{1+1}{0-1}[/tex] = [tex]\frac{2}{-1}[/tex] = -2
y = -2x + 1

Answer:
Tariffs hurt Southerners?
Step-by-step explanation:
