Step-by-step explanation:
= 4(n + 2)
= 4.n + 4.2
= 4n + 8
Answer:
b = 35
Step-by-step explanation:
Use the butterfly method (Cross multiply):
b × 13 = 13b
65 × 7 = 455
So you would have:
13b = 455
Divide both sides by 13.
You will get b = 35
Hope this helps!
8, 10, 12
A helpful equation:
x+x+1+x+2 = 30
Combine like terms
3x + 3 = 30
Subtract 3 from each side
3x = 27
Divide each side by to isolate x
x = 9
x = 9. However, 9 is not an even number. Let’s subtract 1 from 9 to get the first even number.
The first number is 8. The best two even numbers after 8 are 10 and 12.
8 + 10 + 12 = 30, thus this is the sequence.
4,248 times 0.90 equals 3823.2; so 3823.2 students are enrolled.
