Answer:
1 hour 24 minutes
Step-by-step explanation:
49/35=1.4
Answer:
(x+3)(x+5)
Step-by-step explanation:
Unit rate is a ratio between two different units with a denominator of one. When we divide a fraction's numerator by its denominator, the result is a value in decimal form. For example: 8/4 = 2 and 3/6 = 0.5. When we write numbers in decimal form, we can write them as a ratio with one as the denominator.
For example, we can write 2 as 2/1, and 0.5 as 0.5/1. However, since that approach can be a little clumsy, we usually drop the one. That said, it's important to remember the one is there, especially when working with unit rates.
For instance, 8 miles/4 hours = 2 miles/hour. Notice again that, while we did not include the 1, we did include the unit 'hour' Miles per hour is a familiar expression, as are unit rates such as:
interest/amount invested
revolutions/minute
salary/year
Conversationally, the word ''per'' indicates we are using a unit rate.
Answer:
Yes, <em>z</em> will be greater than <em>x.</em>
Step-by-step explanation:
Given expression is 
now let <em>y = 2 </em>and <em>x = 1</em>
Then, 
where 
i.e. <em>3 > 1</em>
on simplifying the given expression in terms of y
now suppose if <em>x = 7 and z=3 </em>then,
which gives value of y in terms of negative integer which is not possible according to the given statement since y is a positive integer. Therefore, if y is a positive integer then z will be greater than x.
B
The answer is b. Because you x can be a negative, but you’re squaring it so it will equal a positive, and if you add 4, it is still 4 or greater
