Answer:
7x+3y-z
Step-by-step explanation:
Starting off by separating the different variables, you should get:
(3x + 2x ) + (-z + 2z) + (3y)
Then you simplify in between the parentheses...
(5x) + (z) + (3y)
And you finally simplify the equation with only a single number of a certain variable to get your answer...
5x + z + 3y

Answer:
$43.20
Step-by-step explanation:
The price with tax is 100% + 8% = 1.08 times the price before tax. The discount multplies that price by 100% -20% = 0.80. The discount multiplier is the same whether the discount is applied before or after the tax.
The combined effect of the two multipliers is ...
... 1.08 × 0.80 = 0.864
so the discounted price with tax added is 0.864 × $50 = $43.20
_____
Perhaps you're supposed to figure the tax (8% of $50 = $4), add the tax ($50 +4 = $54), then subtract the discount (20% of $54 = $10.80) to get
$54.00 -10.80 = $43.20
Answer:
1200 centimeters
Step-by-step explanation:
if you have 100 centimeters in 1 meter and there are 12 meters you can just multiply the number of centimeters by 12 or whatever number is needed in this case 12 so when you multiply 12 x 100 you get 1200
Solve for m by simplifying both sides of the equation, then isolating the variable.
m = -2.5
