Answer:
x < 7
Step-by-step explanation:
The hollow circle represents less than or greater than. Because the arrow points to the left, the line is representing less than.
Expression: <span>y÷4−3</span>
When <span><span>y=20</span><span>y=20</span></span>, the value of the expression is 2.
18 is 15% of 120. Because 15% = 0.15 and 15% of 120 is 120x0.15= 18.
Answer:
x = - 6
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 9 when x = 3, thus
k =
=
= - 3
y = - 3x ← equation of variation
When y = 18, then
18 = - 3x ( divide both sides by - 3 )
x = - 6
