Answer:
y = 60
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 10, then
20 = 10k ( divide both sides by 10 )
2 = k
y = 2x ← equation of variation
When x = 30, then
y = 2 × 30 = 60
Answer:
x = 1 . 14
Step-by-step explanation:
5x + 7 + 2x + 1
5x + 2x + 7 + 1
= 7x + 8
= x = 8 / 7
x = 1.1 4
Hope this answer helps you :)
Have a great day

Answer:
It would be C
Step-by-step explanation:
since the whole area of the circle is 18 and the sector takes up one-fourth of the circle you would just divide 18 by 4 to get 4.5
The anaswer would be a because if it is streched that long then the graph would be 2
