Answer:
5x + 4x = 20
Step-by-step explanation:
You have your x and y values and if you substitute them in you find yourself with 40 - 20 = 24 this doesn't make sense. So you get another answer which can be set to 20 and 40 - 20 = 20 therefore you you can make sure that your line intersects with your x and y values.
Answer:
y= -2/5x + 5
Step-by-step explanation:
40 / [20 - 4(7-4)]...u have to do what is in the brackets first
40 / [ 20 - 4(3)]
40 / [ 20 - 12]
40 / 8
5 <===
Put the number in the formula and do the arithmetic.
C = (5/9)(329 - 32)
C = (5/9)(297)
C = 165
The temperature in °C is 165.
