Answer:
- 36
Step-by-step explanation:
First evaluate g(18), then substitute the value obtained into h(x), then substitute the value obtained here into f(x).
g(18) = =
= 6, then
h(6) = | 4(6) | - 12 = | 24 | - 12 = 24 - 12 = 12, then
f(12) = - 3(12) = - 36

Since both fractions mean to divide, I like to divide the numerators by the denominator, and I'll show you how I do it ----
7/10 = 0.7, or 70%
4/5 = 0.8, or 80%
You can now see that the 80% is larger than the 70%, and, this is why 7/10 is less than 4/5 :D

In accordance with given data correct answer is
RD= 85% * 50 = 0.85 * 50 = 42.5 ounces of red dye.
Good luck!!!
Final answer:
Phil used 42.5 ounces of red dye in the process of making 50 ounces of purple dye, given that the mixture was 85% red dye.
Explanation:
The question is asking us to determine how many ounces of red dye was used in the mixing process to produce 50 ounces of purple dye. Phil used a solution of 15% blue dye and 85% red dye. Therefore, the amount of red dye used can be computed by taking 85% of the total amount of dye made, which is 50 ounces.
To do this, we multiply the total ounces of dye (50 ounces) by the percentage of red dye (85%) used in the mixture. Mathematically, this is represented by the equation: (85/100) * 50.
Therefore, Phil used 42.5 ounces of red dye in the mixing process to make the purple dye.

Answer:
Number of times 4 is gone through to get 48 = 12
Step-by-step explanation:
The number which is formed after the product is given to be 48
Now, we need to find how many times 4 is gone through to get the final result as 48
4 × 1 = 4
4 × 2 = 8
4 × 3 = 12
4 × 4 = 16
4 × 5 = 20
4 × 6 = 24
4 × 7 = 28
4 × 8 = 32
4 × 9 = 36
4 × 10 = 40
4 × 11 = 44
4 × 12 = 48
Hence, Number of times 4 is gone through to get 48 = 12

The system of linear equations that models the situation is given as follows:
- x + y = 125.
- 5x + 8y = 775.
What is the system of equations?
As stated in the problem, the variables of the system are given as follows:
- Variable x: number of quick washes.
- Variable y: number of premium washes.
They washed 125 cars, hence the first equation is defined as follows:
x + y = 125.
They made $775 from a combination of $5.00 quick washes and $8.00 premium washes, hence the second equation is given as follows:
5x + 8y = 775.

$150 per night
Use a system of equations using x (cost of hotel) and y (cost of car):
5x + 6y = 1170
7x + 8y = 1610
Solve for y in one of the equations and then use substitution to solve for x in the other:
6y = 1170 - 5x
y = (-5/6)x + 195
7x + 8((-5/6)x + 195) = 1610
7x + (-20/3)x + 1560 = 1610
(1/3)x +1560 = 1610
(1/3)x = 50
x = $150 a night
