Four students took an exam. The fraction of the total possible points that each received is given. Which student had the highest score? A. Monica, 22/55
B. Lily, 17/20
C. Nikki, 4/5
D. Sydney, 3/4

Answer:

The student took 28 classes

Step-by-step explanation:

What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.

6c + (c - 7) + (9c - 8) + (4c + 6) =

Answer:

x = 11

Step-by-step explanation:

if we need to find the value of x then we need to

5x + 10 = 65 ( Vertically opposite angles are same )

5x = 65 -10

5x = 55

x = 55/5

x = 11

Answer:

x=11

Step-by-step explanation:

5x+10=65

5x=65-10

5x=55

5x÷5=55÷5

x=11

No

Step-by-step explanation:

Given

- 2x + 4 = 18

note the inverse of - 2 is - [tex]\frac{1}{2}[/tex] not - 2

However , the first step is to isolate the term in x by subtracting 4 from both sides.

- 2x = 18 - 4 = 14 ( divide both sides by - 2 )

x = - 7

The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Given that:

[tex]R(t) = t^2 + 7t + 159[/tex]

[tex]c(t) = t^2 + 131[/tex]

The profit function P(t) is calculated as follows:

[tex]P(t) = R(t) - c(t)[/tex]

So, we have:

[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]

Open brackets

[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]

Collect like terms

[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]

[tex]P(t) = 7t + 28[/tex]

Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Answer:

154 2/3 m²

Step-by-step explanation:

14 1/2 x 10 2/3

First, make the mixed numbers into improper fractions:

29/2 x 32/3

Simlify by cross cancelling if you can:

29/1 x 16/3

Then, multiply:

29/1 x 16/3 = 29 x 16/1 x 3 = 464/3

Finally, turn the new improper fraction into a simplified mixed number:

464/3 = 154 2/3

The area is 154 2/3 m²

Step-by-step explanation:

you should remove 8 out of 10 then 2 will remain

then add negative 5 to both sides then we will left with -3x = -3

divide -3 on both sides we find x = 1

Answer:

x=1

Step-by-step explanation:

-3x + 5= -8 + 10​

Combine like terms

-3x+5 = 2

Subtract 5 from each side

-3x+5-5 = 2-5

-3x = -3

Divide by -3

-3x/-3 = -3/-3

x =1
