So, let's say the soft drink equals y and the sandwich equals x.
x + y = 9.9
The sandwich costs 3.5 times as much as the soft drink
x = 3.5y
Therefore, we can replace x with 3.5y since they're the same thing
3.5y + y = 9.9 <-- That's the equation :)
Answer:
1 (anything with the exponent of 0 always equals 1)
Step-by-step explanation:
The arrangement of the numbers in descending order (largest to smallest) are as follows;
- a). 5.5, 4, 29/33, -3/4, -2.365
- b). 10, 5.855, 5/8, 1/2 -2π, -8
<h3>What is the arrangement of the numbers in descending order in each case?</h3>
It follows from convention that the positive numbers are larger than negative numbers and hence, should appear before negative numbers when the arrangement is in descending order.
Consequently, the numbers can be evaluated and arranged as in the answer above with positive numbers increasing rightwards and negative numbers decreasing leftward of 0 on the number line.
