Answer:

6x+20=5x+25

5 days

Step-by-step explanation:

Let x = the days that they have the same amount of signatures

We know Anna has 20 currently and gets 6 per day, so we can use y=mx+b to describe her linear relationship.

We also know that Sam has 25 and gets 5 per day, so we can again use y=mx+b to describe his linear relationship.

Since both equations equal the variable y, we can say they equal each other and set up 6x+20=5x+25.

Then you subtract 20 from both sides and subtract 5x, so you are left with x =5, or 5 days until they have the same amount of signatures

Hope this made sense :D

aleksklad [387]

Answer:

1 whole pie and 6 slices

Step-by-step explanation:

Because you're dividing each slices into two, then you're multiplying the number of slices by 2 and you get 8 slices for one pie. So that feeds the 8 friends. Then you should just buy 6 extra slices for his kids.

Can y’all guys help please

tiny-mole [99]

Answer:

Step-by-step explanation:

What we need to do is find the operation between f(x) and g(x) that results in h(x).

Notice how there's a pattern, the value of h(x) is always equal to the values of g(x) and f(x) added together.

This can be represented by the expression (g+f)(x), the expression in D.

An architect is designing square windows with an area of ( x 2 + 20x + 100) ft2 . The dimensions of the windows are of the form

umka21 [38]

A) The dimensions are (x+10) by (x+10).
B) The perimeter is given by 4x+40.
C) The perimeter when x is 4 is 56.

The quadratic can be factored by finding factors of c, the constant, that sum to b, the coefficient of x. Our c is 100 and our b is 20; we want factors of 100 that sum to 20. 10*10=100 and 10+10=20, so those are what we need. This gives us (x+10)(x+10 for the factored form.
Since the dimensions are all (x+10), and there are 4 sides, the perimeter is given by 4(x+10). Using the distributive property we have 4*x+4*10=4x+40.
To find the perimeter when x=4, substitute 4 into our perimeter expression:
4*4+40=16+40=56.

Bernice takes a multiple-choice test, each question having 4 choices. If Bernice has no idea of any answer and simply guesses, f

hoa [83]

We want to find the probability that Berenice gets all the answers correct.

1 question:

Each question has 4 options, each option has the same probability of being the correct option, so she has a 25% of randomly selecting the correct option.

Then the probability here will just be equal to the number of correct options (1) over the total number of options (4)

p = 1/4

2 questions:

We already know the probability for one question, then the probability of getting two questions correct will be equal to the product of the individual probabilities for each question:

p = (1/4)*(1/4 = 1/16

3 questions:

Similar approach as before:

p = (1/4)*(1/4)*(1/4) = 1/64

4 questions:

p = (1/4)*(1/4)*(1/4)*(1/4) = 1/256
