Answer: The smaller number is 9 and 5/42. The larger number is 53 and 13/21.
To find these answer you have to write the following two equations.
x - y = 44 and 1/2
7y - x = 10 and 3/14
Then, you can use the substitution method to solve them. Change the first equation to: x = 44 + y. Substitute that into the second equation and solve for y. Once you have that, plug it back into the first equation and solve for x.

Answer:
40 miles per hour
Step-by-step explanation:
Change 300 minutes to hours. There are 60 minutes to hours
300 minutes * 1 hour/ 60 minutes = 5 hours
Now take the miles and divide by hours
200 miles / 5 hours = 40 miles per hour
There's an infinite amount of numbers that round to 8.21 when rounded to the nearest hundredth, for example:
8.211
8.209
8.214
8.21145683204
etc...
Just pick whichever two numbers you like :)
Answer:
4v^2-25
Step-by-step explanation:
(2v+5)(2v-5)
Using (a-b)(a+b)=a^2-b^2, simplify the product
(2v)^2-5^2
To raise a <u>product to a power</u>, raise each factor to that power.
4v^2-5^2
Evaluate the <u>power.</u>
4v^2-25
