Answer:
The answer is 250.
Step-by-step explanation:
The smallest integer that can be round off to 300 is 250.
e.g
250
≈ 300
249
≈ 200
Answer:
B. 2x – 1 = 13 and x = 7
Step-by-step explanation:
We are given 4 equations and a solution for each. We have to tell which of the given solution satisfies the given equation.
Option A.
2x -1 = 13 and x = 6
Using this value in the equation, we get:
2(6) -1 = 13
12 - 1 = 13
11 = 13, which is not true. Hence this option is not valid
Option B.
2x - 1 = 13 and x = 7
Using the value in the equation, we get:
2(7) - 1 =13
14 - 1 =13
13 = 13, which is true. Hence this option is valid.
Option C.
2x + 1 =13 and x = 7
Using the value in the equation, we get:
2(7) + 1 = 13
15 = 13, which is not true. So this option is not valid
Option D.
2x - 1 = 13 and x = 11
Using this value in the equation, we get:
2(11) - 1 = 13
21 = 13, which is not true. Hence this option is not valid.
4k(3n+2) this is basically just factoring out a common multiple which in this case is a k and a 4
Answer:
just using normal x and y coordinates
4x + 2y = 36
where x = 5
that is 4×5 = 20
where y = 8
that is 2×8 = 16.
