Answer:
The distance of the playground is 540m
Step-by-step explanation:
Here, we are interested in calculating the length of the playground given the information in the question.
Where to attack the question from is the segment that states that he took a break after 480m and also had 2 breaks. Thus, the distance traveled would be 480 * 2 = 960 m
Now, to find the length of the track, we add the distance covered plus the distance uncovered. Mathematically that would be 960m + 120m = 1,080m
In the last part of the question, we are told that the track is twice as long as the playground. This means that the length of the playground or the distance of the playground is 1080/2 = 540 m
Answer:
m equals √16, n= 3 1/2

Answer:
B. Only (-3,5)
Step-by-step explanation:
1. Plug in the x values from the answer choices and see if it gives you the y-value in the answer choices.
A. y=-3(-2) - 4
= 6 - 4
y = 2
The ordered pair for answer A is (-2,4) where the y-value is 4. Well, when you plugged in -2 for x you got 2, not 4. So A can't be the right answer.
B. y=-3(-3) - 4
= 9- 4
y = 5
The y-value in this ordered pair (-3,5) is indeed 5, so this answer holds true.
Therefore, the answer is B because it is the only ordered pair that has the correct solution.
Answer:
the mango cost 1.75$ each and the peach 0.75$
Step-by-step explanation:
M= mango
P=peach
we know that Hudson spend 16$ buying 7 mangos and 5 peaches. So we can write the equation
(1) 16=7M+5P---> (2)P=(16-7M)/5
and we know that Austin spend 14.50 buying 4 mangos and 10 peaches.
we write the equation
(3)14.50=4M+10P
and we replace the P with the equation (2)
14.5=4M+10*(16-7M)/5
14.5=4M+2*(16-7M)
14.5-32=4M-14M
M=1,75$
and now we replace M in eq. (2)P=(16-7*1.75)/5=0.75$
