please answer these if you know algebra pleaseee?
How do you do these step by step and/or how to figure them out and do them:
On a map, the scale indicates taht 4 inches represent 125 miles. How many inches would represent 88 miles?
The high school Congress sold 350 cookes at a bake sale. It cost $45 to make teh cookies, and they sold them for $0.35 each. How many cookies would they need to sell in order to break even?
Create a situation (write a story) to represent the equation 2x / 7 = 5
23 % of 90 is what number?
12 is what percent of 40?
6% of what number is 98?
THANK YOU SO MUCH WHOEVER TEACHES ME HOW TO DO IT, WHY TO DO IT, AND HOW TO DO THEM STEP BY STEP!!! THANK YOU
I'll walk you through the first question, and hopefully you'll figure the rest out from that.
First, we need to pick something to represent the number of inches that would represent 88 miles. We'll call this "x."
Now, since this is a scale, we know that there will be ratios involved. 4 inches = 125 miles, x inches = 88 miles. Set this up as a proportion (it's easier to write it out):
4/125 = x/88
Cross multiply to get...
125x = 4*88
125x = 352
Divide both sides of the equation by 125 to isolate x.
125x/125 = 352/125
x = 2.816
Therefore 2.816 inches represents 88 miles.
Good luck with the rest.
