2/14 = 1/7
then 1/7×1400 = 200
Answer:
10.5in
Step-by-step explanation:
DC=16in is similar to OP=12in.
So the ratio is 12/16=3/4.
Now AD=14in.
MP=AD×ratio=14×3/4=21/2=10.5in
62 days = 1364 pages
1 day = x
62x = 1364
x = 1364/62
x = 22 pages each day
Answer:
20mph
Step-by-step explanation:
because when you divide the 280 it goes by 20 mph to get to 280 miles by quarters but in 20s
Call (F) the age of the father and (J) the age of Julio
The F & J are related in this way: F=4J
Now you have a restriction in the form of inequality: The sum of both ages has to be greater or equal than 55.
Algebraically that is: F + J ≥ 55
You can substitute F with 4J to find the solution for J:
4J + J ≥ 55
5J ≥ 55
Now divide both sides by 5
5J/5 ≥ 55/5
J ≥ 11
That Imposes a lower boundary for the value of J of 11, meaning that the youngest age of Julio can be 11
