No guarantee that there will enough hotdogs for the buns, we must find the common multiple between the usual number of hot dogs and buns in each package.
Since we're looking for the smallest common multiple between 8 and 10, we can use the method shown below to compute for the least common multiple.
8 = 2³
10 = 2 x 5
LCM = 2³ x 5 = 40
To purchase 40 hot dogs and buns, you need to buy 5 packages of buns and 4 packages of hot dogs.
Answer:
Hotdog: 4 packages
Buns: 5 packages
Answer:
I would say that they are different because if x - a has a value to the equation then that means a - x will not have the same value because it may be rearranged to a different equation but that doesn't mean that they will have the same value. that explain why x - a and a - x are not the same
Answer:
15.6%
Step-by-step explanation:
$52,000 - 45,000 = $7,000
$7,000 ÷ 45,000 = 0.15555555... ≈ 15.6%
Answer:
C
Step-by-step explanation:
(0,-4) (-4, -3)
-3- -4 / -4 -0 = 1/-4 is the slope
so is C
Answer: she biked 0.8 hour each day
Step-by-step explanation:
Let x represent the number of hours that she jogged on both days.
Let y represent the number of hours that she biked on both days.
Distance = speed × time
On the first day, she jogs at a rate of 6 miles/hour and bikes at a rate of 10 miles/hour. She covers a total of 26 miles that day. This is expressed as
6x + 10y = 26- - - - - - - - - - - - - - - 1
The second day, she continues to jog at a rate of 6 miles/hour, but a hamstring pull slows her biking rate to 5 miles/hour. The second day she covers a total of 22 miles. This means that
6x + 5y = 22- - - - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
5y = 4
y = 4/5 = 0.8
Substituting y = 0.8 into equation 1, it becomes
6x + 10(0.8) = 26
6x + 8 = 26
6x = 26 - 8 = 18
x = 18/6
x = 3
