Answer:
48
Step-by-step explanation:
We are asked that the value of (4n + 7) will be an integer > 1 and < 200, for how many integer values of n.
So, equating (4n + 7) with 200 we can get the value.
4n + 7 = 200
⇒ 4n = 193
⇒ n = 48.25
Hence, the value of n will be the largest integer less than 48.25.
Therefore, the number of integer values of n will be 48. (Answer)
Answer:
- 11 ≤ x ≤ - 3
Step-by-step explanation:
Inequalities of the type | x | ≤ a , have a solution of the form
- a ≤ x ≤ a
Then
| x + 7 | ≤ 4
- 4 ≤ x + 7 ≤ 4 ( subtract 7 from each interval )
- 11 ≤ x ≤ - 3
Step-by-step explanation:
The center of the circle with equation (x-2)²+ (y+3)² is given by (2, -3).
So, the student made an error on writing the center
S/2 + 8 = 54
To find out the cost of the spikes, we must isolate the variable.
first, subtract 8 from both sides.
S/2 +8 = 54
-8. -8
Now we have
S/2 = 46
now, to find out what s is on its own, we must multiply by the recipricle of S/2. if that doesn't make sense to you, just think of it as cancelling the division by multiplying by 2.
s/2 = 46
*2. *2
s = 92
The spikes cost $92.
It is neither 25^2 which equals 625 once you square root it .
