Answer:
21.6, 5.4
Step-by-step explanation:
a=4b
a+b-2=25
5b-2=25
5b=27
b=27/5
a=4*27/5
Answer:
Approximately 3771 times
Step-by-step explanation:
Let x be the number of times the wheels turn in 5 miles.
Given that, 1mile = 5,280ft
Thus, 5 miles=5 × 5,280ft=26400ft
From the question ,we can deduce the following ratios :
140 ft : 20 mins
26400ft : x
Cross multiply;


Divide through by 140.


Answer:
8/8
Step-by-step explanation:
There are two pies, and each one was cut into fourths. There are four fourths in a whole, and since there are two wholes, there are two four fourths (I don't know if this makes sense).
Basically, multiply how many fourths (four per pie) by how many pies there are.
4 x 2 = 8
There are 8 pieces.
Answer:
2 19/21, 61/21
Step-by-step explanation:
First, lets make the denimonators, "3 and 7" common. 3 and 7 are prime numbers, so the common denonminator is "21".
For 7/3, multiply by "7/7" and for 4/7 multiply by "3/3".
49/21 + 12/21
Add.
61/21
61 is a prime number so this answer will be your final answer.
(unless you have to put it as a mixed number which would be 2 19/21)
