Answer: 50
Explanation: 2/5x - 2 = 18
Divide the fraction to make a decimal
2 ÷ 5=0.4
0.4x-2=18
0.4x=20 Add 2 to 18
20 ÷ 0.4=x Divide 20 by 0.4 to get x
x=50
Answer:
1. 3/25
2. 22/25
3. 2/25
4. 7/50
5. 1 6/25
Step-by-step explanation:
Hello!
Since the angles are same side alternate angles they are equal to each other
60 - 2x = 70 - 4x
We solve this algebraically
Add 4x to both sides
60 + 2x = 70
Subtract 60 from both sides
2x = 10
divide both sides by 2
x = 5
Hope this helps!
