Answer:
x=20
Step-by-step explanation:
we know the straight angle theorum...
3x+80+2x=180
5x=100
x=20
Answer:
90
Step-by-step explanation:
1. Start by making functions for the numbers
2. You can plug in these functions into a graph to figure out the x variable
- The intersection point of the two lines reveals the x and y
- The x would be your answer
3. To check if your x is right, plug it back into the two equations
- .89(90)+36=116.1
- 1.29(90)=116.1
Since 9 is over 5 it rounds up: 40,000
Answer:
(I dont know which way your supposed to do it)
+4 +4
3x = 18
÷3 ÷3
X = 6
