There are 15 oranges
Solution:
Let "x" be the number of oranges
Let "y" be the number of pears
Let "c" be the number of children
There are 3 times as many pears are oranges
Number of pears = 3 times the number of oranges
y = 3x -------- eqn 1
If a group of children receive 5 oranges each, there will be no left over
So, "c" children receives 5 oranges each, there will be no left over
number of oranges = 5(number of children)
x = 5c ------- eqn 2
If the same group of children receive 8 oranges each, there will be 21 pears left over
number of pears = 8 oranges(number of children) + 21
y = 8c + 21
Substitute eqn 1
3x = 8c + 21 ---- eqn 3
Substitute eqn 2
3(5c) = 8c + 21
15c - 8c = 21
7c = 21
c = 3
Substitute c = 3 in eqn 2
x = 5(3)
x = 15
Thus there are 15 oranges
Answer:
15 orangs
Step-by-step explanation:
There are 15 oranges

x = 5c ------- eqn 2

number of pears = 8 oranges(number of children) + 21
y = 8c + 21
Substitute eqn 1
3x = 8c + 21 ---- eqn 3
Substitute eqn 2
3(5c) = 8c + 21
15c - 8c = 21
7c = 21
c = 3
Substitute c = 3 in eqn 2
x = 5(3)
x = 15
Thus there are 15 oranges

The area of the figure is 51 cm².
Given that,
A four-sided figure with the top side labeled as 10.2 cm.
The height is labeled 5 cm.
This shape is a trapezium.
Total length of the base = 6.2 + 4 = 10.2 cm
Area of the figure = 10.2 × 5 = 51 cm²
Hence the required area of the figure is 51 cm².

(7 inches)/(32 feet) = (13 inches)/(x feet)
7/32 = 13/x
7x = 32*13
7x = 416
x = 416/7
x = 59.4285714 approximately
Round this value however your teacher instructs.

Answer:
First part is 1:2 because there is 1 hour to every 2 shows. Second part is 3:6 shows because 3 hours is 6 shows. Hope this helps, please rate brainiest answer!
Answer:
Principal = $ 800
Time = 4 years
Rate of Interest = 9% compounded Semi Annually
Time = 4× 2=8 periods
As, we have to find balance after 4 years, so we will use the formula for amount in terms of Compound interest.
Amount(A)
Balance after 4 years = $ 1137.68
Your answer would be be subtract 3
