Answer: B. a^4/b^12
Step-by-step explanation:
Hello,
Here's my solution:
Let n = the lesser of the two consecutive even integers; so what will be a good way to represent the greater of the two consecutive even integers? I say n + 2.
Let's write the equation:
n = ((n+2)/2) + 10
I'll multiply both sides of the equation by 2 to eliminate the denominator, getting:
2n = 2[((n+2)/2) + 10]
This reduces to:
2n = n+2 + 20
Which can be further simplified to:
2n = n+22
Subtracting n from both sides we get:
n = 22
So n, the lesser consecutive even integer is 22. The greater consecutive even integer is 24.
Let's check this solution by substituting n = 22 into our original equation:
n = ((n+2)/2) + 10
22 = ((22+2)/2) + 10
22 = ((24)/2) + 10
22 = (12) + 10
22 = 22 - it checks!
Answer:
The third option: 3(x-4)
Step-by-step explanation:
In this case factoring means we want our x variable to be on its own and not have a coefficient, so:
3x-12
= 3·x + 3·4
= 3(x+4)
Answer:
385 golf balls
Step-by-step explanation:
margin of error = (z*)(s) / sqrt n
where z* = 1.96 with 5%/ 2 = 0.025 area in each tail
margin of error = (z*)(s) / sqrt n
1.2 yards = (1.96)(12 yards) / sqrt n
solve for n
n = 384.16
385 golf balls (always round up)
4y = - 2x + 12
y = - 2/4x + 3
The y intercept is 3
