Answer: A: 180= 90+4x+x
B: x=18
Step-by-step explanation:
1. Every triangle has a length of 180
2. So all the measurements combined would equal 180
3. So write the equation 180=90+4x+x
4. Let‘s simplfy, 180=90+5x
5. Subtract 90 from each side, 90=5x
6. Divide each side by 5, 18=x.
7. Double check our work! 90+(4*15)+18=180
Answer:
r = -1/2
Step-by-step explanation:
To find r, divide any number in the set by the previous number in the set and reduce the fraction if possible. Check multiple numbers to make sure r is consistent between all entries...
-200/400 = -1/2
100/-200 = -1/2
-50/100 = -1/2
So r = -1/2
It’s J
In the equation y=mx+b, B is the y-intercept and since the equation is y=-1/3x+2, the line crosses at two in the y-axis and since the fraction is negative it goes down.
