Help please I don’t get this

Mathematics
1 answer:
Leviafan [203]3 years ago
6 0

Answer:

$2.35 for one video

Step-by-step explanation:

You set up two equations:

$7.50= p + 2v

$12.20= p + 4v

You then set both equal to p

p=-4v+12.20 and p=-2v+7.50

So you can set them equal to each other and solve for v (the cost of one video)

v= $2.35

"If an integer n is odd, then n+1 must be even."
gladu [14]

Answer:

True.

Step-by-step explanation:

Let me clear it to you by an example:

if you take n=1,3,5,7,...... which are odd numbers

then adding 1 with them will give you n+1=2,4,6,8.... which are even numbers.

That's how, if an integer n is odd, then n+1 must be even.

Similarly, if you let n as even numbers, then n+1 will be odd.

The French club is sponsoring a bake sale.if their goal is to raise at least $140,how many pastries must they sell at $3.50 each
aleksklad [387]
"raise at least $140" tells you that, whatever the variables may be, the french club's profit needs to be 140 or more

they're selling pastries at $3.50 each, so we'll say that p is the number of pastries

140 >/= 3.50p

$140 must be greater than or equal to the profit from sold pastries

then just solve the inequality from there by isolating your variable:

140 >/= 3.50p

divide both sides by 3.50

40 >/= p

so they must sell at least 40 pastries to raise $140 dollars
