Answer:
4
Step-by-step explanation:
To find MEAN, add up <em>all</em> the values in a data set and then divide by the <em>number</em> of values.
6+2+7+3+2 = 20
Number of values in data set: 5
20÷5= 4
Answer:
a = 0
Step-by-step explanation:
4(a-2) = 2(a-4) + 2a
4a - 8 = 2a - 8 + 2a
4a - 2a - 2a = -8 + 8
0 = 0
we have that
Applying proportion
x/9=5.5/3
solve for x
x=9*(5.5/3)
x=16.5 ft
therefore
<h2>the answer is 16.5 ft</h2>
Answer:
The system of equations are;
4.75t + 7.50b = 790
t = 2b
where t is the number of tacos and b is the number of burritos
Step-by-step explanation:
In this question, we are concerned with writing the system of equations that could help us determine the number of tacos and burritos sold.
Firstly, we start with defining variables. Let the number of tacos sold be t and the number of burritos sold be b
*there we twice as many burritos as tacos sold. What this simply means is that the number of tacos sold is twice the number of tacos.
Mathematically that could be written as ;
t = 2b ••••••••••(i)
Now, let’s work with the revenue;
Each taco is sold at $4.75 and he sold a total of t tacos. The revenue realized from tacos sold is thus $4.75 * t = $4.75t
The money realized from selling b burritos at $7.50 each would be $7.50 * b = $7.50b
The addition of both of these will give the total revenue of $790
Thus, we have;
4.75t + 7.50b = 790 ••••••• (ii)
