We have been given an equation 
. We are asked to solve our given equation for x.
First of all, we will separate expression with x on one side of equation. We can do it by subtracting 5 from both sides of equation.
Now we will switch the sides as:
Now we will divide both sides by 
as:
Therefore, the value of x would be 
.
Answer:
Cristiano will have enough money to buy bike in 9 weeks.
Step-by-step explanation:
Given:
Cost of the bike = $189
Money saved = $99
Money saving each week = $10
We need to find the number of weeks will he have money to buy bike.
Solution:
Let the number of weeks be 'x'.
Now we can say that;
Money saved plus money saving each week multiplied by number of weeks is equal to cost of the bike.
framing in equation form we get;
Subtracting both side by 99 using subtraction property of equality we get;
Dividing both side by 10 using division property of equality we get;
Hence Cristiano will have enough money to buy bike in 9 weeks.
Answer: a. a paired analysis is appropriate
b. a paired analysis is not appropriate
Step-by-step explanation:
The paired analysis sometimes is refered to as a statistical procedure which is used to know if the mean difference that exist between two observations is zero or not. It should be noted that in a paired analysis, each subject is measured twice, and this beings about the pairs of observations.
a. Here, the paired analysis is appropriate due to the fact that similar measurement which are the calories are taken for several days for both the vegetarian and the non vegetarian such are two pairs of sample.
b) In this case, the paired analysis is not appropriate. Here, the pairs of samples don't undergo identical treatment.
So 5 1/2 pages in 12 minutes
rewrite as eleven/2
Make a proportion
pages over minutes = pages over minutes
in an hour, there are 60 minutes
11/2 / 12 = x / 60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 = x
She will read 27.5 pages in an hour.
How many pages in 3 hours?
that is 60 * 3 minutes
180 minutes
Use the proportion of pages/minutes = pages/minutes
plug in what you are given
<span>11/2 / 12 = x / 180
Cross multiply
(11/2 * 180) = 12x
990 = 12x
divide both sides by 12
82.5 = x
She will read 82.5, or 82 1/2, pages in 3 hours (or 180 minutes ;) )
Hope this helps </span>
