This equation shows how the total cost of visiting the science museum as a member is related to the number of visits. c = 9.8v +

LiRa [457]

Well it's giving you what the cost is (42.3), so plug that in for $c$ :

$42.3 = 9.8v + 22.7$

And now you need to solve for the number of visits ( $v$ )!

$19.6 = 9.8v$

$v=2$

So you can visit the museum a maximum of 2 times!

A math test has a total of 20 problems some problems are worth two points and some are worth three points the whole test is wort

kari74 [83]

Answer:

There were 12 questions worth 3 points

Step-by-step explanation:

Let x = 2 point questions

let y = 3 point questions

What we know:

x + y = 20 (questions)

so to solve for x we tweak our equation:

x = 20 - y

Now we need an equation to explain out question set up:

2x (2 point questions)

3y (2 point questions)

2x + 3y = 52 (52 being our total possible points)

Now we take our x = 20 - y and substitute it into our 2x + 3y = 52 equation.

2(20 - y) + 3y = 52

Next we distribute the 2 through the parenthesis:

40 - 2y + 3y = 52

Now, gather the like terms:

40 + y = 52

Subtract 40 from both sides:

y = 12

Revisit x + y = 20 and sub 12 in for Y:

x + 12 = 20

x = 8

8 2-point questions would be 16 points

12 3-point questions would be 36 points

16 + 36 = 52 (which matches the max value of our test)
