Answer:

<em></em>(x,y) = (5,15)<em></em>

<em></em>

Step-by-step explanation:

Given

Nickels = x

Pennies = y

Minimum of 20 coins means:

x + y \ge 20

A nickel worth $0.05

A penny worth $0.01

So, the worth can be represented as:

0.05x + 0.01y \le 0.40

<em>See attachment for graph</em>

<em></em>

From the attachment, the solution is:

<em></em>(x,y) = (5,15)<em></em>

Answer:

x = 7

Step-by-step explanation:

Notice that in the triangle, the angle is either known or in terms of x. This means we can make an equation: 82 + (9x - 6) + (6x - 1) = 180. Now, add up tthe terms to get 15x + 75 = 180, or 15x = 105 or x = 7.

jill traveled to the ferry office and back. the trip there took 5 hours and the trip back took 4 hours. she averaged 65 mph on t
antoniya [11.8K]

We know from physics class that the formula for distance of a linear motion is given as:

d = v t

Where,

d = distance travelled

v = average velocity

t = time it took to reach the destination

Since the distance going to the office and back is just similar, therefore we can simply equate the two:

v1 t1 = v2 t2

Where 1 signifies going to the office and 2 signifies going back from the office. Therefore this yields to:

v1 * 5 hours = 65 mph * 4 hours

v1 = 52 mph

 

<span>Answer: The average speed going to the office is 52 mph.</span>
