1)A 2)B 3)B 4)A
not sure why the other person answer said that the answer to 1 is B. an equilateral triangle has all sides at the same length, so the statement is true.
Answer:
900
Step-by-step explanation:
We assume that your 4-digit number must be in the range 1000 to 9999. Clearly, any number ending in zero will meet your requirement:
1000/100 = 10
3890/389 = 10
However, the requirement cannot be met when the 1s digit is other than zero.
__
For some 3-digit number N and some 1s digit x, the 4-digit number will be
4-digit number: 10N+x
Dividing this by N will give ...
(10N+x)/N = 10 remainder x
N will only be a factor of 10N+x when x=0.
So, there are 900 4-digit numbers that meet your requirement. They range from 1000 to 9990.

Answer: c = 7p</h3>
Explanation:
Let's say 5 people get a lunch platter. The cost would be 7*5 = 35 dollars.
Or if 3 people got the lunch platter, then it would be 7*3 = 21 dollars
In general, the cost is 7p dollars where p is a placeholder for a whole number. So that's how we end up with c = 7p
I hope you mean 1/5 when you say 1 5. If that's what you mean, then both, Joshua and Melanie, are correct because, both of their equations are the same.
Joshua's - <span>8 ÷ 1/5 = 40 (Since we can divide a number by fraction, we use this rule: keep, change flip. When we use that Joshua's equation turns into 8 * 5/1 = 8*5 = 40, same as Melanie's.)</span>
