Answer:

cost of a box is $3.5

Step-by-step explanation:

given data

sold box = 18

earned = $136.50

solution

we consider here number of boxes of cookies is x

and

for we get Tyler sold  cookies box so number of boxes we divide 702 cookies among 18 is

Tyler sold  = \frac{702}{18}

Tyler sold  = 39 boxes

and

now we consider here y as cost of each box of cookies,

so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes

so

cost of each box = \frac{136.5}{39}

cost of each box = 3.5

Thus, the cost of each box was 3.5

2. Create a linear function that has a rate of change of 3 and a solution at (6, 12).
Ksivusya [100]

Answer:

y = 3x - 6

Step-by-step explanation:

A linear function has the following format:

y = ax + b

In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.

Rate of change of 3

This means that a = 3

So

y = 3x + b

A solution at (6, 12).

This means that when x = 6, y = 12. So

y = 3x + b

12 = 3*6 + b

b = -6

The linear function is:

y = 3x - 6

Proving Pythagorean Theorem
MrRissso [65]

Answer:

45

Step-by-step explanation:

{a}^{2}  +  {b}^{2}  =  {c}^{2}

ssubstitute a and b for any of the numbers (3 or 6) and get 36+9 which is 45

45 =

{c}^{2}

so you would need to find the square root to get c

Eight times ten plus six times one plus two times one-tenth plus seven times one-thousandth.

Step-by-step explanation:

(8 x 10) = eight times ten

(6 x 1) = six times one

(2 x 0.1) = two times one-tenth

(7 x 0.001) = seven times one-thousandth

I am not always the best with the equations to words stuff, so please comment if I am wrong!
