Think of it this way...ratios can be written as fractions...so 18:14 can be written as 18/14...so basically, ur equivalent ratio is just finding equivalent fractions.
18/14 is equivalent to 9/7, 36/28, and 54/42...so 3 equivalent ratios are :
9:7 , 36:28, 54:42.
588 million kilometers or 365 million miles
U take it step by step and it also depends on what kind of problem
Answer:
x=27
Step-by-step explanation:
3x+9 is a right angle because 3x+9 + a right angle make a straight line
3x+9 +90 = 180
Subtract 90 from each side
3x+9 = 90
We now can solve for x
3x+9-9 = 90-9
3x = 81
Divide each side by 3
3x/3 = 81/3
x=27
