115 = 10X + 0.25(60)
115 = 10x +15 (this is the equation to use)
100=10x
x=10 hours
You have the formula already, just plug in 30 for s (speed) and solve for d (distance).
I'm pretty sure it should be 2h+3
Answer:
Step-by-step explanation:
Area of rectangle = length * width
= (3x + 2)(4x + 10)
= 3x *(4x + 10) + 2*(4x + 10)
= 3x *4x + 3x *10 + 2*4x + 2*10
= 12x² + <u>30x + 8x</u> + 20 {Combine like terms}
= 12x² + 38x + 20
Answer:
The family bought 2 bags of chips
Step-by-step explanation:
Let the number of chips bags be = x
The number of candy bars = twice as much as the number of bags of chip
The number of candy bars = 2x
The total cost spent is = $5.50
Therefore cost of all the chips bags + candy bars = 5.50
2x + x = 5.50
3x = 5.50
x = 
x = 1.83
x = 2 (approx)
Thus the number of chips is 2 and the candy bars is 2(2) = 4 bags
