Undefined is the answer because there is no value for x
rDistance (D) = Speed (S) * Time (T)
S * T = r*20/60 mins = r / 3
So r/3
Answer:
1 ÷ 2 pounds
Step-by-step explanation:
The computation is shown below:
As we know that
1 pound = 0.454 Kg
Peanut starting weight = 3 ÷ 4 of a pound.
In the case when the bag is 2/3 full, so the weight is
= 2 ÷ 3 × 3 ÷ 4
= 1 ÷ 2 pounds
Answer:
3
Step-by-step explanation:
24 + (-1) = 23, 12 + (-2) = 10, 8 + (-3) = and 6 + (- 4) = 2, none of the sums are equal to 3, therefore b = 3 would give a prime quadratic. The correct answer is then A. 3
Answer:
32
Step-by-step explanation:
Let x is the number of groups
Let y is the total cost of the ticket
The number of people = 8x
Given that:
Ticket price: $42 for a group of up to 8 people
The cost per ticket decreased by three dollars => the slope is 3
So we can form the equation: y = -3x + 42
Here Marcos ticket cost 30 dollars, so:
y = -3x + 42 = 30
<=> -3x + 42 = 30
<=> x = 4
So the number of people in Marcos group is: 8*4 = 32
