Answer: 18
Step-by-step explanation:
Evaluate 7 r − 15 /s
Given that r = 3 and s = 5
7r - 15/s
Substitute 3 for r and 5 for s in the above expression
7(3) - 15/5
= 21 - 3
= 18
Answer:
um well if C would be the X then
Step-by-step explanation: 2 times 2 is four now you have to figure out which number minus 4 is 5 which would be nine then you go back to the 3x part and the only way to get nine from a 4-3 is it would have to be a negetive so then you see that 2 plus seven is 9 or 2- (-7) is 9 so you find three times -7 =-2.33333333
Let w be the number of weeks. He withdraws $25 per week, so in w weeks, he withdraws 25w. He starts with $500, so after w weeks he has 500 - 25w. He wants this amount to be at least $200. "At least" means "greater than or equal to."
500 - 25w >= 200
-25w >= -300
w <= 12
Answer: Keith can withdraw $25 per week for at most 12 weeks.
Prime factorization means finding the prime numbers that you can multiply to make a certain number.
So, he prime factorization of 36 would be 2 x 2 x 3 x 3 or 2, 2, 3, and 3.
Just to make sure: 2 x 2 = 4 4 x 3 = 12 12 x 3 = 36
