Answer:
3.62
Step-by-step explanation:
Let
x = cost of cereal
y = cost of milk
5x + 2y = 31.24
x = $4.80
Substitute into the equation
5x + 2y = 31.24
5(4.80) + 2y = 31.24
24 + 2y = 31.24
2y = 31.24 - 24
2y = 7.24
y = 7.24 / 2
y = $3.62
Therefore,
1 gallon of milk cost $3.62
The equation for r in the distance formula is r = d/t
Answer:
b=2.5
Step-by-step explanation:
The given line has equation:
The x-intercept is (b,0)
The y-intercept is (0,b)
The area of triangle QOP
The area of triangle QRS
The area of triangle QRS and QOP are in the ratio 9:25
We must negate the area under the x-axis.
But 0<b<4
Therefore b=2.5
VERIFY
The area of triangle QOP
The area of triangle QRS
We must take absolute value because this area is below the x-axis.
