Let these there numbers be assigned to variables x, y and z. Since you want to find the sum, add all numbers. However, the sum has boundaries between 10 and 20. Therefore, you will have to use inequality symbols. The two addition equations that could be formulated are:
<em>x+y+z > 10</em>
<em>x+y+z < 20</em>
Answer:
? = 10
Step-by-step explanation:
13 - (10) = 7-4 ....... 2×2 =4
3 = 3
Answer:

Step-by-step explanation:
Start with $30.
Subtract $5 for the admission: $30 - $5 = $25.
Now he has $25 to spend on rides. Each ride costs $3.5, so we divide $25 by $3.50.
$25/$3.50 = 7.14
Since the number of rides must be a whole number, he can go on 7 rides.
Hello!
79.99 equals 100%, or in other words, 79.99 = 1.
To find the net price, you'll need to find the discount, multiplying the total by 40% (or 0.4):
Now, just subtract the initial price by the discount:
So, the net price of the car is approximately 48.00.
Hope this helps!
