Answer:
umm... there is no problem
PEMDAS: distribute the negative to (-2-5x) so it becomes (2+5x)+(-2)=18
Add 2 to both sides: 2+5x=20
Subtract 2: 5x=18
Divide 5: x= 18/5
The two ratios that are equivalent to, 2:9 are 18:81 and 12:54. Hope it helps
Step-by-step explanation:
5/2 times x = 1
5/2 * x = 1
5x =2
x = 2/5
x = 0.4
1 1/2 or 3/2 because there is 4 more than 8 which is a half.
