Answer:
<h2>
-3 < x < -1 → x∈(-1, -3)</h2>
Step-by-step explanation:
(1)
x + 5 < 4 <em>subtract 5 from both sides</em>
x + 5 - 5 < 4 - 5
x < -1
(2)
x - 3 > -6 <em>add 3 to both sides</em>
x - 3 + 3 > -6 + 3
x > -3
From (1) and (2) we have
x < -1 and x > -3 → -3 < x < -1 → x∈(-1, -3)
Answer: 21 questions
Step-by-step explanation:
Turn it into a number sentence.
72% of x amount of questions is 15
0.72(x) = 15. Divide both sides by 0.72
x= 20.83333 round to nearest whole number
x= 21 questions

ANSWER IS
$131.35
If 1 liter of milk is $17 3/4 we just need to find the cost for 7 2/5.
Since we’re working with money we have to turn the $17 3/4 and 7 2/5 into a decimal so its ($17.75) and 7.40
Anyways we multiply those numbers to find the cost of 7 2/5 liters
( 17.75 x 7.40) and the answer is $131.35
