Emily drove 3/7 of the total distance and holly drove the rest which explains that holly drove 4/7 of the whole distance.
if 4 parts of the distance equals 24 miles, then 1 part would be 24/4 is 6.
since emily drove 3 parts of the whole distance, it is 6 × 3 = 18 miles.
travelling time of emily = 18/45 = 0.4 hr
travelling time of holly = 24/54 = 0.4 hr
--> total traveling time = 0.8 hr
i hope it is right
7+ 3x= -8
-8-7=-15
-15 divided by 3= -5
-5 is the answer
3 over 8 plus 2 over 3 plus 1 over 3 = 11 over 8 or 1.375
Answer:
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
Step-by-step explanation:
Let
x -----> number of pages that Polina read
y ----> number of pages that Marcus read
we know that
x+y=108 ----> equation A
x=5y -----> equation B
substitute equation B in equation A and solve for y
![5y+y=108\\6y=108\\y=18](https://tex.z-dn.net/?f=5y%2By%3D108%5C%5C6y%3D108%5C%5Cy%3D18)
Find the value of x
![x=5y -----> x=5(18)=90](https://tex.z-dn.net/?f=x%3D5y%20-----%3E%20x%3D5%2818%29%3D90)
therefore
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
