Step-by-step explanation:
a/20=10
=a=10×20
a=200
Answer:
y = 3/2 x - 9/4
Step-by-step explanation:
bring all the y's to one side.
4y = 6x-9
divide by 4 to isolate the y
y = 6/4x - 9/4
simplify
y = 3/2 x - 9/4
<h3>The ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1</h3>
<em><u>Solution:</u></em>
Given that,
Five hundred sixth-grade students were surveyed
Which means,
sixth-grade students = 500
125 had traveled on an airplane
<em><u>What is the ratio of total sixth-grade students to the number of students who had traveled on an airplane?</u></em>
Therefore,
total sixth-grade students : students traveled on airplane = 500 : 125
<h3>Ratio = 500 : 125</h3>
Reduce to lowest terms,
Divide both sides by 5
<h3>Ratio = 100 : 25</h3>
Further reduce to simplest terms,
Divide both sides by 25
<h3>Ratio = 4 : 1</h3>
Thus the ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1
<span>1) Choosing 3 of 5 toppings for pizza (you CAN have extra of something you like)
meaning u can have the same toppings as ur 3 choices
so for each of the 3 choices, there are 5 options
total possible outcome = 5 x 5 x 5 = 125
</span><span>2) Choosing 3 of 5 toppings for pizza ( you canNOT order "doubles")
meaning each choice can be selected just once
so after the first choice, there is only 4 options left; after 2nd, just 3
total possible outcome = 5 x 4 x 3 = 60
</span>
It’s definitely less than 8 because when two people work together it takes less time
