4 - 5x = 2x + 25
4 = 7x + 25
-21 = 7x
-3 = x
4 - 5x + 2x + 25 = ac
4 - 5(-3) + 2(-3) + 25 = ac
4 - (-15) + (-6) + 25 = ac
19 + (-6) + 25 = ac
38 = ac
Answer: -2 and 26
Step-by-step explanation:
-2 * 26 = -52
-2 + 26 = 24
Answer:
D
Step-by-step explanation:
You have to have exactly the same thing underneath the radical. So for example in choice A you have sqrt(2) and sqrt(3) underneath the radical. They are not the same. Choice A is not the answer.
Choice B has the same problem sqrt(5) is not the same thing as sqrt(3) and choice B is not the answer.
Choice C has sqrt(5) and sqrt(6) as your choice. They are not the same. C is not correct.
D is the answer. Both choices have sqrt(7) as the radicals. They are both 7. They are the same.
Answer:
3 1/4
Step-by-step explanation:
1) Convert 6 1/2 into a fraction and add it to 1/2.
6 -> 12/2
12/2 + 1/2 = 13/2
2) Divide the result by 2 (or multiple the result by the reciprocal of 2)
13/2 x 1/2 = 13/4 or 3 1/4
Hope this helped ^^
