which statements about this problem are true? check all that apply.
the question asks how much of the $15 joey has left after buying a sandwich and a can of juice.
this is a part-whole problem.
to find out how many dollars joey has spent already, multiply $5.60 by $1.50.
to find out how many dollars joey has left after buying just the sandwich, subtract $5.60 from $15.00.
the answer will be written in this form: "joey will spend $ more on a sandwich than on a can of juice."

see below

Step-by-step explanation:

Joey spends 5.60 +1.50

The total he spends is 7.10

He will have 15.00-7.10 =7.90 left for other things

The question asks how much of the $15 Joey has left after buying a sandwich and a can of juice.    True

This is a part-whole problem.   False  This would be a part part whole problem if anything, not a part whole problem.  It truly depends on how your teacher defined it.

To find out how many dollars Joey has spent already, multiply $5.60 by $1.50.   False   This is addition and subtraction

To find out how many dollars Joey has left after buying just the sandwich, subtract $5.60 from $15.00.   True  The sandwich is 5.60 , subtract that from 15 and that is how much he has left after just buying the sandwich

The answer will be written in this form: "Joey will spend $ more on a sandwich than on a can of juice."  False, this is not what the question is asking for, it is asking for how much he has left after buying the juice and sandwich

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
