Answer:
Step-by-step explanation:
The wording "fewer than" is translated to the math symbol "less than". The variable n represents the number of students.
<em>the number of students</em> is fewer than 18
translates to ...
n < 18
__
The wording "at least" translates to the math symbol "greater than or equal to."
<em>the number of students</em> is at least 15
translates to ...
n ≥ 15
Answer:
1. 10.92
2. 26.98
3. 1.98
4. 3.61
Step-by-step explanation:
(Going left to right)
To find the area you have to multiply L x W, so for the first rectangle you do 2.8 x 3.9, which is 10.92
For the second one you do 7.1 x 3.8, which is 26.98
then you have to do 2.2 x .9, which is 1.98
and for the last one, because it's a square you simply have to do 1.9 x 1.9 which is 3.61
Answer: $497.40
Step-by-step explanation: $497.40
540*.06 (which is 6%)= 32.4
This is how we find the amount of taxes Benito paid
32.4+540= 572.4
You add the tax to the total of the price of the laptop.
572.4-75= 497.4
You take the total of what be paid and subtract the amount of money that he received after filling out the rebate form .
Answer:
(y-12)/4
Step-by-step explanation:
If g(x) is the inverse of f(x)
and f(x) = 4x + 12
f⁻¹(x) = g(x)
let f(x) be represented as y
f(x)
= y
y = 4x + 12
subtract 12 from both sides
y-12= 4x
divide both sides by 4
(y-12)/4 = x
so f ⁻¹ (y)= (y-12)/4 so g(x) = (x-12)/4
