Answer:
x= 8
Step-by-step explanation:
The equation of direct variation is
y = kx
When y = 50 when x = 40
50 = k* 40
Divide each side by 40
50/40 = k
5/4 = k
The equation is
y = 5/4x
Let y = 10
10 = 5/4x
Multiply each side by 4/5
4/5 * 10 = 5/4 x * 4/5
8 = x

Answer:
17.5
Step-by-step explanation:
90% sure
Solution:
Given c = 3 and d = 10 – 3 = 7
<u>To find the value of y:</u>
Taking square root on both sides of the equation.
<u>To find the value of x:</u>
Taking square root on both sides of the equation.
<u>To find the value of z:</u>
Taking square root on both sides of the equation.
Hence the value of .
45º-------------------6 people
360º------------------ x
x=(360º x 6 people) / 45º=48 people.
solution: 48 people.
