Answer=10:40
Explanation:
Don’t know how to type the symbol in font of the 50 so I will substitute
£50=$50
So 1:4
Add it up
1+4=5
So 5 total units
$50=5
Divided by 5
$10=1 units
So 1:4=10:10 times 4=10:40
Answer:
8x = 136
Where: x = 17
Step-by-step explanation:
Joshua is writing a novel. He wrote the same number of pages each day for a 8 days. At the end of 8 days he had 136 pages complete. Write an equation relating x, the number of days, to y, the total pages.
Let the number of pages read per day = x
Hence, the number of pages after 8 days = 8 × x = 8x
Total number of pages = y= 136
Therefore:an equation relating x, the number of days, to y, the total pages.
= 136 = 8x
Solving for x
136/8 = x
x = 17
