200 meters per minute.
A minute is 60 seconds. 60 divided by 3 is 20. 20 Times 10 is 200.

Examine this system of equations. Which numbers can be multiplied by each equation so that when the two equations are added toge

Karolina [17]

The first equation must be multiplied by 18 and second equation must be multiplied by 8

Solution:

Given system of equations are:

$\frac{1}{4}x -\frac{1}{6}y = 5$ --------- eqn 1

$\frac{4}{5}x +\frac{3}{8}y = 10$ -------------- eqn 2

Multiply the second equation by 8 both sides to remove the fraction in the variable y

$8(\frac{4}{5}x +\frac{3}{8}y = 10)\\\\\frac{32x}{5} + 3y = 80 -------- eqn 3$

Multiply the first equation by 18 both sides to obtain the coefficient -3 in the variable y

$18(\frac{1}{4}x -\frac{1}{6}y = 5)\\\\\frac{18}{4}x -3y = 90 ---------- eqn 4$

Add eqn 3 and eqn 4

$\frac{32}{5}x +3y +\frac{18}{4}x -3y = 80+90\\\\\frac{32}{5}x+\frac{18}{4}x = 170$

Thus the y-term is eliminated

Therefore, first equation must be multiplied by 18 and second equation must be multiplied by 8

The spinner is divided into eight equal sections marked with eight different colors what situation could be represented by the s

meriva

I believe the answer you looking for is Probability.

This means that if someone spinned that wheel, they have a probability of getting the color they need.

For instance,
Let's say this wheel had the colors red, orange, yellow, green, blue, indigo, purple, and pink.
If I wanted the color red on the spinner, I have a 1/8 chance to spin the color red. I have a 7/8 chance of NOT spinning red. However, let's say the wheel had 4 colors that were pink and 4 colors that were blue. If I wanted to spin the color pink, I would have a 4/8 chance OF spinning it and a 4/8 chance of NOT spinning it. 4/8 is also equivilant to 1/2.

I hope this helps you understand!!
Please mark brainliest!!
Thanks!!

If the area of a trapezoid is 300, what are the dimensions?

ludmilkaskok [199]

It should be 75 if you divide the area by the amount of sides. I don’t know if I’m right if I’m wrong I’m sorry!
