15/3= 5 If you are not sure for my answer, check your calculator.
Explanation:
It depends on the definition of "factor" that you use.
One dictionary defines "factor" to be ...
"a number or quantity that when multiplied with another produces a given number or expression"
In that sense, 7 can be a factor of 3, because 7 × (3/7) = 3.
___
Often we use the term "factor" when we mean "integer divisor", or "positive integer divisor". Using this last definition, the only factors of 3 are 1 and 3.
Other times, we use the term "factor" to mean "prime factor." By this definition, the only factor of 3 is 3 itself.
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
