Answer:
d = |145 − (−235)|
Step-by-step explanation:
Answer:
x=-2
Step-by-step explanation:
-4(x-7)=36
divide both sides by four
x-7=-9
move constant to the right and change its sign
x=-9+7
calculate the sum
x=-2
Prime numbers are not divisible by any number but themselves or 1.
A) 115 is divisible by 5, so it is not prime
B) 273 is divisible by 3 (you get 91), so it is not prime
C) 317 is prime! only divisible by itself or 1
D) 414 is divisible by 2, so it is not prime. Even numbers are never prime because they are divisible by 2!
Answer:
C
Step-by-step explanation:
The best way to solve this is to transfer -217 to the other side. So add 217 to both sides
0 ≤ 7 + 217 - 28v Combine
0 ≤ 224 - 28v Now add 28v to both sides
28v ≤ 224 Divide by 28
28v/28≤224/28
v ≤ 8
You should have 2 questions on your mind.
- Why go to all the trouble of putting things on the opposite sides?
- What is the answer
1. You so all that trouble so that you don't have to switch the < to >. As long as you have the letter and its coefficient > 0, then you are going to be right.
2. The is v is less than or equal to 8. That's C
