Hi there! 5 bottles of water for $3 would make $0.60 per bottle. 0.6 * 15 = 9. That means 15 bottles of water should equal $9, but instead it is $8. Based on that, no. The costs for bottles of water is not proportional to the numbers sold. Basically, you can divide to find unit prices and multiply the number of another item to see if the numbers are proportional.
The answer is x=-4, (3<span>±i)/2</span>
Answer:
a = 8 m
Step-by-step explanation:
Since, given is an isosceles right triangle.
So, by Pythagoras theorem:
You have less money if you subtract 14.99 - 140 ounces you get -125.01 and if you subtract the other one the other more less than the previous one 100 ounces is better.
Answer:
The number is 132
Step-by-step explanation:
First we write an equation to represent the problem.
Anytime a story problem says "a number" we can use x. Sum means addition. Divided is division. "Is" tells us where to put the equals sign.
12+x/8=18
Solving for x:
Multiply both sides by 8 to get rid of the fraction.
12+x=144
Subtract 12 from both sides.
x=132
