Answer:
a. 20x > 10x + 80
b. •20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
Step-by-step explanation:
10x + 80 = number of seashells Pilar has.
20x = number of seashells Marisol has.
answer for a: 20x > 10x + 80
answer for b: 20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8

Answer:

Step-by-step explanation:
we are given that

since m is greater than or equal to 0 it's a positive number therefore, the square root of m is defined and recall that √x²=|x| thus

remember that,|a|•|x|=|ax| hence,

and we're done!

For this question, we must find "10 is what percent of 40"
The equation for this is:








To check if this is correct, you can do the following below:
What is 25 percent (%) off $40?
Use the formula and replace the given values:
Amount Saved = Original Price x Discount % / 100. So,
Amount Saved = 40 x 25 / 100
Amount Saved = 1000 / 100
Amount Saved = $10
In other words, a 25% discount for an item with original price of $40 is equal to $10
