Answer:
$1770 for 25 hours
Step-by-step explanation:
600 × 225 = 135000
135000 ÷ 90 = 1500 min
1500min=25 hours
$2.95×600= $1770
Answer: A
Step-by-step explanation:
y-int: 140
slope: -4
to find the slope u gotta use the (y2-y1)/(x2-x1) formula
120-140 = -20
5-0 = 5
-20/5 = -4
The driver can drive around the track 54 times for $12. Thus for one dollar, he can drive around the track 54/12 times, or 4.5 times. If for each dollar he drives around 4.5 times, for 8 dollars, he can drive around 8*4.5 or 36 times.
If there are 207 students in 9 classes, in 1 class, there are 207/9 students, or 23 students per class. Since there are 23 students per class and there are classes, there are a total of 23*6 or 138 students in total.
Liam practices 24 times in 4 days. Thus he practices 24/4 or 6 times per day. His brother practices 12 times in 3 days. Thus he practices 12/3 or 4 times a day. Thus their rates are not equivalent.
For the top part, factors are the numbers that can be multiplied together to get a certain number. So for question 5, what times what is 12? Well 1x12, 2x6, and 3x4. Those numbers are your factors. A tip is that once your lower numbers are start to match your higher, then you get no more. So like once you start saying 3x4=12 you should stop because you can’t go past 3 anymore because of 4.
Now for GCF, that stands for greatest common factor. So for question 9, what are the factors of 40 and 48? List them out then find the Greatest (largest) Common (same) factor. I hope that help!
