Answer:

16 bicycles and 21 tricycles

Step-by-step explanation:Both bicycles and tricycles have 1 set of handlebars. Bicycles have 2 wheels while tricycles have 3.

Using this information, set up a system of equations, where b is the number of bicycles and t is the number of tricycles:

b + t = 37

2b + 3t = 95

Solve by elimination by multiplying the top equation by -2:

-2b - 2t = -74

2b + 3t = 95

t = 21

Then, plug in 21 as t into one of the equations:

b + t = 37

b + 21 = 37

b = 16

So, there are 16 bicycles and 21 tricycles

Answer:

all u got to dooooo is take two sets of pointssss and find the rate of change using the formula y1-y2 x1/x2

Step-by-step explanation:

Solve using substitution. I know that the answer is (1,1), but I have to show my work and I forgot how to do it.

Answers

If y = -x + 2, then substituting this into the first equation lets you solve for x :

x + 4y = 5

x + 4 (-x + 2) = 5

x - 4x + 8 = 5

-3x = -3

x = 1

Now solve for y :

y = -x + 2 = -1 + 2 = 1

So the solution is indeed (x, y ) = (1, 1).

Part of the formula for compound interest is dividing the interest state by the number of compounds per year ( for monthly that is 12)

The amount also get raised to the amount of time multiplied by the compounds.

The formula would be A = p(1+ 0.1399/12)^(12t)

What is the IQR (Inter Quartile Range
0, 21, 45, 3, 1, 5, 25

Answers

Answer:

Interquartile range = 24

Step-by-step explanation:

First we need to put the sequence in order from lowest to highest.

0, 1, 3, 5, 21, 25, 45

5 is the median and then from 5 to 0 we need to find the lowest interquartile in between it which is 1.

Highest interquartile from 5 to 45 finding the middle will be 25.

Interquartile range = highest interquartile - lowest quartile

25-1 = 24

Jax takes a bus from Washington DC to New York City. The trip takes 5 hrs. and 47 minutes. He arrives in New York City at 1:58 pm. what time did the bus leave Washington DC?

Answers

Answer:

8:11 a.m.

Step-by-step explanation:

We need top subtract 5:47 from 1:58 pm.

Since we cannot subtract 5 from 1, we add 12 to the 1:58 hours digit.

1 + 12 = 13

1 pm is 13 hours of the day.

13:58 - 5:47 = 8:11

Step-by-step explanation:

You can see in the diagram that there are 5 x variables and eleven which make up the total diagram that says 36 so it would have to be 5x+11 = 36

Answer:

5x + 11 = 36

Step-by-step explanation:

Looking at the tape diagram, if you count the x, you have 5x and then you have 11. So it would refer to as 5x + 11 and the total of the tape diagram is 36. So it would be :-

5x + 11 = 36
