Answer:
6, 12, 18, 24, 30
Step-by-step explanation:
1+2+3+4+5 = 15
90 divided by 15 is 6
6x1 = 6
6x1 = 12
6x1 = 18
6x1 = 24
6x1 = 30
Answer:
The bear is 35 years of old now.
Step-by-step explanation:
Leon wanted to know the age of the black bear at the zoo.
He is informed that if he adds 10 years to the age of the bear and then doubles it, the bear would be 90 years old.
Let the present age of the bear is x years.
So, according to the above condition we can write
2(x + 10) = 90
⇒ 2x + 20 = 90
⇒ 2x = 70
⇒ x = 35
So, the bear is 35 years of old now. (Answer)
Answer:
16. Adults = $12
17. 750 ml
18. $9
19. 96 students
20. 5/6x
Step-by-step explanation:
16.
A child pays = $9
Bus fee = 1/3 of $9
= 1/3× 9
= $3
Admission fee for a child= amount paid - bus fee
= $9 - $3
= $6
What was the admission fee for adults, if children get in for haprice
Children = 1/2 of adults
$6 = 1/2 × adults
Adults = 6÷ 1/2
= $12
Adults = $12
17.
Leaking rate = 10 ml per minutes
One and quarter of an hour
1 hour = 60 minutes
Quarter of an hour = 15 minutes
Total time = 75 minutes
Air lost in 75 minutes = 10 ml × 75
= 750 ml
18. 4 glasses for $3
1 dozen of glasses = 12
12 glasses = $x
4 = 3
12 = x
Cross product
4*x = 3*12
4x = 36
x = 36 / 4
= 9
x = $9
19.
Total students = x
1/2x = soccer
Rugby = 1/2 of 1/2x
= 1/2 * 1/2x
= 1/4x
24 = 1/4x
x = 24÷1/4
= 24 × 4/1
x = 96 students
20.
Total petrol = x
Petrol in the tank = 1/2x
Petrol used = 1/3 of 1/2x
= 1/3 × 1/2x
= 1/6x
Petrol remaining after the trip = x - 1/6x
= 6x-x/6
= 5/6x
You use it at the end of a sentence and it looks like this! It means like loud
