Ron has 22 cards
number one tip in math, try to create equation!
set number of cards Ron has as x (always set x as what you are looking for)
set number of cards Tori has as (x-9) because if Ron has 9 more cards than Tori that's same thing as saying Tori has 9 cards less than Ron
Number of cards Tori and Ron has need to equal 35
Therefore,
x + (x-9) = 35
Solve:
2x-9=35
bring over 9 to other side
2x=44
divide both sides by 2
x=22
So number of cards Ron has is 22
Answer:
that looks like it is right
Answer:
not possible.
Step-by-step explanation:
number of invitations luanne has to address after x days = 120-15x
number of invitations Darius has to address after x days = 120 + 15(7-x)
so, if the number of invitations should be the same for both of them,
we have to equate their number of invitations
120-15x = 120 + 15(7-x)
subtracting 120 from both the sides,
-15x = 15(7-x) = 105 -15x
adding we 15x on both sides, we wont find any solution for x.
so, this isnt possible or the question must be wrong.
The solution of the graphed system of equations y = -x² + x + 2 and y = -x + 3 is (1,2)
<h3>How to solve the equations?</h3>
The system of equations is given as:
y = -x² + x + 2
y = -x + 3
From the graph in the complete question, we have the following point of intersection between the equations
(x,y) = (1,2)
The point of intersection between the equations is the solution
Hence, the solution of the graphed system of equations is (1,2)

Well we know that 1 centimeter = 50 miles, so 2 centimeters = 100 miles. Now we have to find what 0.4 centimeters equals. To do this we must find 40% of 50.
We simply multiply 0.4 and 50 to get our answer.
0.4 × 50 = 20. So we add 20 to 100.
20 + 100 = 120
So 2.4 centimeters = 120 miles.
Hope I helped!
