Answer:

m = 575h

Step-by-step explanation:

Given

Rate = 575 miles/hour

Required

Determine the equation for the model

Represent the number of hours with h and the miles with m.

Using distance formula:

Distance = Speed * Time

In this case, it is:

Miles = Rate * Hour

So, we have:

m = 575 * h

m = 575h

PLEASE HELP ASAP, I NEED A PERFECT SCORE. I'M IN A STRESS AND PANIC MODE BECAUSE I MAY NOT FINISH 9TH GRADE, PLZ HELP ME ANSWER
grandymaker [24]
M(x) = 5x + 4     n(x) = 6x - 9

Part 1 (m + n)(x) = 5x + 4 + 6x - 9
                           = 11x - 5

Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36

Part 3 m[n(x)] = 5(6x - 9) + 4
                       = 30x - 45 + 4
            = 30x - 41

A coconut shy at the village fair offers three throws for $1, or seven throws for $2. In one hour, 187 throws are made and the a
kotykmax [81]

Total throws = 187

Let three throws = 3t

And

Seven throws = 7s

So

3t + 7s = 187 -------------- (1)

While total collected money = $57

Money for three throws = 1t

Money for seven throws = 2s

Hence

1t +2s = 57 ------------------(2)

Now solving both equations, so multiply second equation by 3 and subtract it from equation (1);

Equation (2) becomes 3t + 6s = 171

While subtracting it from equation (1) gives the final equation as below.

s = 16

Putting s = 16 in equation (2);

1t + (2x16) = 57

1t + 32 = 57

t = 25

Thus 25 people bought three throws and 16 people bought seven throws.

As for 25 people having three throws = $25

And

16 people having seven throws = 2x16 = $32

So total earned money = 25 + 32 = $57

<span>Hence proved. </span>
