Answer:
Inequality: 2*x + 3 ≤ 11
Solution: x ≤ 4
Number line: see picture attached (in the context of the problem, x must be greater than zero)
The solution means that you can buy at most 4 pounds of strawberries
Step-by-step explanation:
You go to the store to buy fruits. You have $11, you need 2 pounds of apples that costs $3, and you want strawberries, which cost $2 each pound. How many pounds of strawberries can you buy?
The inequation that represent this situation is:
2*x + 3 ≤ 11
where x represents pounds of strawberries. The solution is get as follows:
2*x + 3 - 3 ≤ 11 - 3
2*x ≤ 8
2*x/2 ≤ 8/2
x ≤ 4
Answer:
Step-by-step explanation:
Hello,
We can write that, x being the second number
(4 + 2*x) *x = 198
Let's solve this equation.
We are looking for positive number so the solution is 9.
And the first number is 4 + 2 * 9 = 4 + 18 = 22
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
