Hey there!

ANSWER: [tex]f=-16[/tex]EXPLANATION:

[tex]\frac{f}{4}-5=-9[/tex]

Simplify both sides and you get:

[tex]\frac{1}{4}f-5=9[/tex]

Now add 5 to both sides and you get:

[tex]\frac{1}{4}f=-4[/tex]

Now you have to multiply both sides and you get:

Given f(x) = 4(x - 8), determine the value of f(10).

Answers

Answer:

f(10) = 8

Step-by-step explanation:

f(x) = 4(x - 8)

Let x = 10

f(10) = 4 ( 10-8)

       = 4 ( 2)

      = 8

Here, we are provided with a polynomial in x and it's general value in variable X is also given.

[tex]f(x) = 4( x - 8)[/tex]

We need to find the value of f(10)

For this, we need to substitute the value of x with 10, because we are required to find f(10)

Given polynomial, f(x) = 4(x - 8), Putting value of x

[tex]f(10) = 4(10 - 8)[/tex]

[tex]f(10) = 4(2)[/tex]

[tex]f(10) = \boxed{ \red{8}}[/tex]

Step-by-step explanation:

Brian wants to make it for 3 people, so everything must be divided by 4 since 12/4=3.

7/4=1.75

4 1/4 divided by 4=1 1/16

Answer:A is 21 cups of flour and B is 12 3/4 cups of sugar

Two times the complement of an angle is 23 less than the supplementary of the angle. What is the measure of the angle?

Answers

Answer:

Step-by-step explanation:

Let the angles be x and y

If the two angles are complementary then their sum is 90 i.e x+y = 90

x = 90-y

If the two angles are supplementary, then their sum is 180 i.e x+y = 180

x = 180-y

If two times the complement of an angle is 23 less than the supplementary of the angle, this is written as;

2(90-y) = (180-y)-23

180-2y = 157-y

-2y+y = 157-180

-y = -23

y = 23

Hence the angle is 23°

Three girls-- Kali, Annie, and Xiaoling -- go on a trip with their youth orchestra. The three girls share the cost of the hotel. The bill comes to $295.48. It includes $13.25 for some food that Annie orders and $14.00 for cleaning Xiaoling's uniform. What is the dollar amount of each girl's share of the hotel bill?

Answers

Answer:

About $107.57

Step-by-step explanation:

if you add up the bill cost and the 13.25 for the food and 14.00 for cleaning Xialing's uniform its $322.73 divide that between the 3 girls and you get about 107.57

Each girl would pay Kali = $89.41

Annie = $102.66

Xiaoling  = $103.41

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

Foe example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Total bill amount = $295.48

Now, the amount excluding the amount of food ordered by Annie

= 295.48 - 13.25

= $282.23

and, the amount excluding Cleaning amount

= 282. 23 - 14

= $268.23

So, Each Girl would pay

Kali = $ 268.23 / 3 = $89.41

Annie = 89.41 + 13.25 = $102.66

Xiaoling = 89.41 + 14 = $103.41
