Hello! So, we could set up a proportion to solve this, because the price and CPI increased at the same rate. Let's set it up like this: 34.6/82.4 = 0.75/x. This is because we know the prices from the 1960's, but we don't know the gallon of milk price in 1980, and we line them up like that to make sure we get the proper answer. Cross multiply the values in order to get 34.6x = 61.8. Now, divide each side by 34.6 to isolate the variable. x ≈ 1.7861 and other numbers behind it or 1.79 when rounded to the nearest hundredth. The price for a gallon of milk in 1980 was about $1.79.
Ok so if a system has no solutions, that means that no value will make it true
infinite solutions means that all numbers wil make the system true
example of no solution
a simplification that gives you
3=0
that is false so no solution
example of infinite
if after simplify you get
x=x
you can put all numer for x and get right answer
the simplified form of an equation with no solution will be in the form a=b where a is not equal to b, basically it gives you an obviously false statement like 3=4
simplified form on an equation with infinity solutions would end up with variable=variable or x=x or y=y
Answer: thanks for the points 1=1==1=1=14+6-3=2
Step-by-step explanation:
No, they're not equivalent
