When working out an equation, if the result comes out like : x = 2, or y = 4.....a variable equal to a number, then there is 1 solution
if the result comes out like : 0 = 4, or 2 = 6...no variable and an incorrect result, then the equation has no solutions because ur lines are parallel.
if the result comes out like : 2 = 2 or 5 = 5...no variable and a true statement, then there will be infinite solutions because ur lines are coincident...they are the same line
Answer:
yes they form a proportion
Step-by-step explanation:
1 to 3 and 7 to 21 are equal
we can check this by multiplying each number in the 1 to 3 ratio by 7 to make it equal with the other ratio, 7 to 21.
(sorry if this is confusing but I hope it helped)
Answer:
top: 0.7, 0.9
bottom:7/10
0.7 = 7/10 because 7 is under tens. If it was 0.34 = 34/100 because 34 is in the hundereds. If it was 0.100 = 100/1000 because 100 is under the thousands. pls brainly trying to level up

271/5 = 54.2 hours
How: 2/5 +2/5+3/5 times 5 (bc its 3 different dogs with different times for 5 days) +3 (for 3 dogs) times 4/5 (bc each dog take 4/5 of an hour each) + 1/5 (for the extra 1/5 of an hour pepper wanted to stay outside)
*Important: in the parentheses are the explanation of why I did each addition or multiplication
