Answer:
nI don't get exactly what your asking but if it's 4n + 5n - 15 + 90 + 3n + 25 + 6n - 10 simplfied then the answer is 18n + 90
Step-by-step explanation:
Add like terms
4n + 5n + 3n + 6n = 18n
-15 + 25 - 10 + 90 = 90

Answer:
£36
Step-by-step explanation:
From the question, we are told that School allots £3000 to spend on a trip to the theatre. With regular cost of tickets of £40 each with offer for 1/5 off
Then the cost of each ticket with 1/5 off= (4/5×40)= £32
From the question, A train ticket for the day will cost £20 each.
Then total cost for each of it = £32+£20
=£52
To determine how much money that the school will have left over, If 3 teachers and the maximum number of students attend, can be expressed below by first calculating the number of students.
Let us denote the number of students as "x"
52(x+3)= < 3000
52x + 156 =< 3000
52x =< 3000 - 156
52x =< 2844
X =< 2844/52
s =< 54.69,
The max. Number of students is 54
Total number of people= Number of students + the 3 teachers
= 54+3= 57
Total cost for 57 people= (£52 × 57 people)= £2964
The amount of money the school will have as left over = (£3000 - £2964)
= £36
Answer:
2050
Step-by-step explanation:
<u>Year 2010</u>
The number of people over 65 years of age =32 million
Total population = 307 million.
P(meeting a person over 65 at random in 2010)
<u>Year 2050</u>
The number of people over 65 years of age =88 million
Total population = 434 million.
P(meeting a person over 65 at random in 2050)
Conclusion: Since 0.2028 is greater than 0.1042, the chances of meeting a person over 65 at random will be greater in 2050
Suppose she paid x shillings for the shares;
Then;
37+9=2x
46=2x
x=23
She bought each share at 23 dollars
