PLS HELP pls pls pls

Answers

Answer:

y=0

Step-by-step explanation:

Simplifying

y + y = 0

Combine like terms: y + y = 2y

2y = 0

Solving

2y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Divide each side by '2'.

y = 0

Simplifying

y = 0

A zebra runs 15 miles per hour faster than an elephant. The zebra runs 8 miles in
the same time that an elephant runs 5 miles. Write and solve an equation to
calculate the speed of each animal.

Answers

Answer:

elephant:  25 mph; zebra:  40 mph

Step-by-step explanation:

The time required is the same in each case, so we need to set up an equation of the form distance1/speed1 = distance2/speed2:

8 miles                  5 miles

------------- = time = -------------

 speedz                 speede

From this we get:

        8                      5

------------------ = -------------------

speede + 15       speede

Cross multiplying, we get:  8(speed e) = 5(speede) + 75, or

3(speede) = 75, or

speede = 25 mph

Then speedz = 25 mph + 15 mph = 40 mph = speedz

If you rent a canoe for 3 hours, you will pay $45.



Write a linear equation to represent the total cost (y) of renting the canoe for x hours.

Answers

Answer:

y = 15x

Step-by-step explanation:

I'm assuming there is no up-front cost. This means that per hour, you need to pay $45/3 = $15, since $45 is for 3 hrs.

y = 15x

Find the value of x please

Answers

Answer:

x = 14

Step-by-step explanation:

Since, given Pentagons are similar because their measures of internal angles are same. So, their corresponding sides would be in proportion.

[tex] \frac{x + 4}{x} = \frac{9}{7} \\ \\ \frac{x + 4 - x}{x} = \frac{9 - 7}{7} \\ \frac{4}{x} = \frac{2}{7} \\ \\ \frac{2}{x} = \frac{1}{7} \\ \\ x = 2 \times 7 \\ \\ x = 14[/tex]

The value of X =14 that is the answer
