A:

Let x = cheese wafers and Y = chocolate

Set up the two equations:  

Total packets: x + y = 11

Total cost: 3x + 2y = 25

B: Solve:

Rewrite x+y = 11 as x= 11-y

Replace x in the second equation:

3(11-y) + 2y = 25

Simplify:

33-3y +2y = 25

Combine like terms:

33-y = 25

Subtract 33 from both sides:

-y = -8

Divide both sides by -1:

y = 8

Now replace y in the first equation to solve for x:

x +8 = 11

x = 3

They bought 3 cheese wafers and 8 chocolate wafers.

Used the substitution method, which eliminates one of the variables so you can solve for the second variable.

The probability distribution for a random variable x is given in the table.
Aleksandr [31]

Answer:

30%

Four times the lesser of two consecutive even integers is 12 less than twice the greater number. Find the integers.
pashok25 [27]
Oh, this one lol. ok
you gotta read it like its a book.
4 x s(i picked that variable) which is 4s together

4s+12 (if they said'12 less than' then the 12 gotta be adding.)
then u have to divide it so its going to look like this:

4s+12= blah blah blah
'twice the greater number' means you gotta do this: 2(s+2)

so the problem is this: 4s+12=2(s+2)

now you solved it and the answer will beeeeee s=-4

Graph the line of the equation 8x/5 - 2y = -8 using its slope and y-intercept
satela [25.4K]

Answer:

y=\frac{4}{5}x+4

Step-by-step explanation:

You'll need to get this equation in slope-intercept form by solving for y. I do a little extra here to get it in the correct form, but I think it's pretty clear. Let me know if I need to clarify.

\\\\\frac{8x}{5}-2y=-8\\\\-2y=-\frac{8x}{5}-8\\\\2y=\frac{8x}{5}+8\\\\y=\frac{4}{5}x+4

Once it's in slope-intercept form, both the slope and the y-intercept are readily available so you can easily graph it. I graphed both of them in the attached image so you can see that they are the same line.
