Answer:
2(n+3) - 6 = 2n
Step-by-step explanation:
Let n stand for lonnie's starting number.
Kristy asks to add 3 to the number. It will become (n+3)
Now he ask to multiply the sum by 2. It will become 2(n+3).
Finally, he ask to subtract 6. It will become 2(n+3) - 6
The expression is : 2(n+3) - 6.
We can simplify it as follows :
= 2n+6-6
= 2n
Hence, the required expression is 2n.
There are several information's already given in the question. Lat us first write them down and then go for solving the problem.
Total number of pupil <span>in Secondary one = 225
Let us assume the number of pupil who do not pay the school fees through GIRO scheme = x
Then
Number </span>of pupil who pay the school fees through GIRO scheme = 14x
So
x + 14x = 225
15x = 225
x = 15
From the above deduction, it can be concluded that 15 pupil did not join the scheme.
Multiply everything in the parenthesis by 3.
9x - 24 = 4x + 6
Add 24 to both sides.
9x = 4x + 30
Subtract 4x from both sides.
5x = 30
Divide both sides by 5.
x = 6
Hope this helps!
Answer:
4^12 or 16777216
Step-by-step explanation:
4^6* 4^6
We can symplify 4^6* 4^6
Since they both have the same base, we can add there exponent:
4^6* 4^6= 4^12
4^12 equals to 16777216
Let's first say that L=W+44
and then remember that perimeter is P=2L+2W
replace the L with W+44
we then get P=2(W+44)+2W, now I'll solve it
P=2W+88+2W
P=4W+88
substitute 288 for P
288=4W+88
200=4W
50=W
so now we now how wide the court is. add 44 to find the length which gives you L=94
as always plug the numbers back into your perimeter equation to ensure L and W are correct
