13x=299

x=23

Answer:

y= 3x - 5

Step-by-step explanation:

y= mx+b is slope-intercept form,

m= slope (3)

b= y-intercept (5)

Therefore, y = 3x - 5 is your form.

If you wanted to calculate it, you'd input the x value of 3, like y = 3^3 - 5 to find your slope intercept.

f = 1/18ir^3

Step-by-step explanation:

Let's solve for f.

3r2ifr=1/6

Step 1: Divide both sides by 3ir^3.

3fir3/3ir3 =1/6/3ir3

f=1/18ir3

Answer:

361.88 in.²

Step-by-step explanation:

Surface area of triangular prism = 2(B.A) + PH

Where,

B.A = base area of triangular base = ½*bh = ½*8*6 = 24 in.²

P = perimeter of triangular base = 7.21 + 7.21 + 8 = 22.42 in.

H = height of the prism = 14 in.

Surface area of the prism = 2(24) + 22.42×14

= 48 + 313.88

= 361.88 in.²

Answer:

x^3 - 2x^2 + 9x - 18.

Step-by-step explanation:

The complex roots occur in conjugate pairs so there are 3 roots 2, 3i and -3i.

So we have:

P(x) = (x - 2)(x - 3i)(x + 3i)

= (x - 2)(x^2 - 9i^2)

= (x - 2)(x^2 - 9*-1)

= (x - 2)(x^2 + 9)

= x^3 + 9x - 2x^2 - 18

= x^3 - 2x^2 + 9x - 18.

Answer:

x = 6

Step-by-step explanation:

Instructions?  I'm assuming you were asked to "solve for x."

To eliminate fractions, multiply both sides by 4.  This results in x = 6.

Answer:

85 students

Step-by-step explanation:

If 17 = 20%

It means is the fifth part of 100%

Because 20% * 5 = 100%

With that logic if we multiply the amount of students by 5 we will get the total of students.

17*5= 85

Answer:

The answer is this:

1/3*12=4/1=4

The expression can be written as 1/3 × 12 and its value is 4.

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

The given fraction is 1/3.

And, the number is 12.

Now, the expression to find the 1/3 of the given number can be written using the multiplication operation as,

⇒ 1/3 × 12

Its value can be evaluated as,

⇒ 1/3 × 12 = 4

Hence, the required expression is 1/3 × 12 and its value is 4.

Based on a linear equation, we will see that they sold a total of 288 cookies.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We have been given that Phil and Matt sell cookies for $0.25 each,

Thus, if they sell x cookies, the total revenue is:

R(x) = $0.25x

Now, we know that they made a total of $72.00,

Therefore, we need to solve the linear equation:

$0.25x = $72.00x

= $72.00/$0.25 = 288

Hence, they sold 288 cookies.
