Ten times the sum of a number and 19 is at most 18. Translate the sentence into an inequality
5(n + 15) ≥ -26
n + 15 ≥ -26/5
n ≥ -26/5 - 75/5
n ≥ -101/5
n ≥ -20.2 or 20 1/5
Let's break down the given sentence step by step:
1. "Ten times" implies multiplying by 10.
2. "The sum of a number and 19" can be represented as: (x + 19), where x stands for the unknown number.
3. "Is at most" means less than or equal to.
4. "18" is the value we are comparing the expression to.
Putting it all together, the inequality can be written as:
10(x + 19) ≤ 18
To translate the given sentence into an inequality, let's break it down step by step:
Step 1: Let's define a variable for the unknown number. Let's call it "x," which represents the number.
Step 2: The sum of a number and 19 can be written as (x + 19).
Step 3: Multiply the sum by 10 to get "ten times the sum," which gives us 10(x + 19).
Step 4: "Is at most" implies that this expression should be less than or equal to the value on the other side of the sentence.
Step 5: The maximum value is given as 18.
Putting it all together, the inequality becomes:
10(x + 19) ≤ 18
sum of a number and 19 ... x+19
Ten times the sum ... 10(x+19)
is at most ... ≤
