Answer:
is the answer.
In decimal y = 43.71
Step-by-step explanation:
Given:
y varies directly with x .
Also x = 7 when y = 18
To Find:
y = ? when x = 17
Solution:
y varies directly with x .
i.e. y is directly proportional to x
∴ 
Where
k = constant of proportionality {Remain Same}
First we will find constant of proportionality k,
∴ When x = 7 and y = 18 we have
∴ 
Now when x= 17 and 
we have
∴
∴ 
Answer:
1/5 or 0.2
Step-by-step explanation:
Answer:
(x,y)=(-1,1)
Step-by-step explanation:
Given that,
3x + 5y = 2 .....(1)
6x - 10y = -16 ....(2)
Finding the value of x from equation (1).
Put the value of x in equation (2)
Put the value of y in equation (1) :
So, the solution of the equations is (-1,1).
Answer:
the idea is to devide the shape into 3 smaller parts.
Step-by-step explanation:
devide it to three areas :
> semi-circle (0.5 * pi * R), R=5
>Square (10 * 10)
> triangle (0.5 * base * height),
bsse =10, height =7
Add them together.
