Answer: Solve for X
4x−5y<1
Step-by-step explanation:
step 1 add 5y to each side
4x−5y+5y<1+5y
4x<5y+1
Step 2: Divide both sides by 4.
4x4<5y+14
x<54y+14
Answer:
x<54y+14
Let's solve for x.
12y−x<3
Step 1: Add (-1)/2y to both sides.
−x+12y+−12y<3+−12y
−x<−12y+3
Step 2: Divide both sides by -1.
−x−1<−12y+3−1
x>12y−3
Answer:
x>12y−3
now just graph 4x-5y<1 shows the given inequalities in slope -intercep form.
By applying the definition of difference, we find that the <em>average daily maximum</em> temperature in Syracuse is 26.55 °C higher than the <em>average daily minimum</em> temperature.
<h3>What is the difference between the average daily maximum temperature and the average daily minimum temperature?</h3>
Herein we must find the difference bewteen the two temperatures, defined as the subtraction of the <em>minimum</em> temperature from the <em>maximum</em> temperature:
x = 21.85 °C - (- 4.7 °C)
x = 26.55 °C
By applying the definition of difference, we find that the <em>average daily maximum</em> temperature in Syracuse is 26.55 °C higher than the <em>average daily minimum</em> temperature.
