Answer:
b
Step-by-step explanation:
If you multiple each side by 3 then they will equal the numbers that b has
The weight loss in these three methods does not differ because the average weight loss is very similar in all 3.
<h3>How to calculate the average weight loss?</h3>
To calculate the average weight loss in these three situations, we must add all the values and divide the result by the number of values, for example:
- 7 + 7 + 5 + 4 + 6 = 29
- 7 + 8 + 8 + 9 + 5 = 37
- 7 + 9 + 7 + 8 + 8 = 39
- 39 ÷ 5 = 7.8
- 37 ÷ 5 = 7.4
- 29 ÷ 5 = 5.8
According to the above, it can be inferred that the hypothesis that the difference between one program and another is not significant enough to consider one plan more or less effective than another, because radically differences are not shown in each case.

Let hot dogs = X
So then soda would be 2x ( two times as much).
Now you have:
X + 2X = 162
Simplify:
3x = 162
Divide both sides by 3:
X =162 / 3
X = 54
2x = 54 *2 = 108
108 sodas and 54 hot dogs were sold.
To solve the expression, the steps are add 19 and multiply by 5
<h3>How to solve the expression</h3>
Given the equation;
-3 = -19 + d/5
First,
Collect like terms
-3+ 19 = d/5
Add the values on the left side
We have
16 = d/5
Cross multiply
16 × 5 = d
We then have
d = 80
Thus, to solve the expression, the steps are add 19 and multiply by 5
