1hr 30 mins= 60mins+30mins=90mins
140$=90mins
In one minute, they make 140/90=14/9
in 9 hours=9*60mins=540mins
540*14/9=840
therefore,they make 840$ in 9 hours

Answer:
The gradient of the line segment between the two points is -1
Step-by-step explanation:
The gradient of the line segment between two points is also known as the slope,
We can find this by using the formula; y₂ - y₁ / x₂ - x₁
The points given to us are;(-1,2) and (-2,3).
This implies x₁ = -1 , y₁=2 x₂ = -2 y₂= 3
We can now proceed to insert our values into the formula;
Gradient = y₂ - y₁ / x₂ - x₁
= 3 - 2 / -2-(-1)
= 1 / -2 + 1
=1/-1
Gradient = -1
Therefore the gradient of the line segment between the two points is -1
Answer:
b = -18
Step-by-step explanation:
Multiply both sides by -6/1 which is the reciprocal of -1/6
(-6/1)*(-1/6)b=3*(-6/1)
b=-18/1 = -18
