Answer:
1,146
Step-by-step explanation:
I did this already.
Check out the image attachment for one way to draw this problem out. Notice how angles AEC and DEB are vertical angles, so that means they are congruent angles
(measure of angle AEC) = (measure of angle DEB)
6x + 20 = 10x
6x + 20-6x = 10x-6x ... subtract 6x from both sides
20 = 4x
4x = 20
4x/4 = 20/4 ... divide both sides by 4
x = 5
The value of x is 5.
Let's check the answer
6x + 20 = 10x
6*5 + 20 = 10*5 ... replace every x with 5
30+20 = 50
50 = 50
We have confirmed the answer.
Answer:
change the expression to y
Step-by-step explanation:
![x + 3y = 9](https://tex.z-dn.net/?f=x%20%2B%203y%20%3D%209)
![3y = - x + 9](https://tex.z-dn.net/?f=3y%20%3D%20%20-%20x%20%2B%209)
![y = \frac{ - 1}{3} x + \frac{9}{3}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B%20-%201%7D%7B3%7D%20x%20%2B%20%20%5Cfrac%7B9%7D%7B3%7D%20)
the gradient is the coefficient of x,
![- \frac{1}{3}](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B1%7D%7B3%7D%20)
In this case, because both numbers are negative, -5.31 is greater then -5.313 as it is closer to the positive numbers on a number line. I hope that helped! :D
Given
Between -40°C and 125°C
°C = 5/9 * (°F-32)
°C ÷ 5/9 = °F - 32
°C * 9/5 + 32 = °F
°F = -40°C * 9/5 + 32 = -360/5 + 32 = -72 + 32 = -40°F
°F = 125°C * 9/5 + 32 = 1125/5 + 32 = 225 + 32 = 257°F
<span>−40 < 5 over 9 (F − 32) < 125; −40 < F < 257</span>
