Step-by-step explanation:
First divide 2/5 to get 0.4. Then divide 30 by 0.4 to get the answer. A simple way to think about it is how many 0.4 grams are in 30 gram tube.
Step-by-step explanation:
A linear function is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. A function is a relation with the property that each input is related to exactly one output. A relation is a set of ordered pairs. Tips for a quiz is watch a yt video about it and also search it up to do some reading. You can ask me some questions but I'm not really good at these things.
Answer:
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -x + 5
// Plug this in for variable y in equation [1]
[1] x - 2•(-x +5) = 8
[1] 3x = 18
// Solve equation [1] for the variable x
[1] 3x = 18
[1] x = 6
// By now we know this much :
x = 6
y = -x+5
// Use the x value to solve for y
y = -(6)+5 = -1
Solution :

Step-by-step explanation:
The reason you haven't gotten an answer to this is because in its current formatting, there is no answer. Here's what I mean:
The first equation is going to be concerning the NUMBER of memberships sold, where m is male and f is female. The total number of memberships was 10:
m + f = 10
Now for the money equation. The total amount of money made from that number of memberships was 3000, where male memberships cost $300 and so do the female memberships, giving us an equation of
300m + 300f = 3000
Go back to the first equation and solve for either m or f. I solved for m in terms of f:
m = 10 - f and sub that into the second equation for m to get:
300(10 - f) + 300f = 3000 and
3000 - 300f + 300f = 3000. Here is where you find the problem. The -300f and the 300f cancel each other out, leaving you with the fact that
3000 = 3000 which it does, but it doesn't give us any viable answer.
I would have to say that since we can't do math on this, that the most credible answer you'll find is that the same number of male and female memberships were sold because 5 male memberships cost $1500 (5 memberships at $300 a piece is $1500) and 5 female memberships also cost $1500.
1500 + 1500 = 3000
45 because you do 210-120 which is 90. 90÷2 is 45.
