Evaluate 3(x – 1) + 2 when x = 5.

What's a real-world problem that can be modeled by the equation 1.25 = 0.75x + 50 ?

olga nikolaevna [1]

Well, you could say that you want to buy something for $1.25. Like a game or a toy or something! So you need to have $1.25 in order to get this item. You have $50 in your savings account you make 0.75 an hour. And then x would represent the number of hours you have to work. It doesn't really make sense since if you have 50$ in your savings account then you would be able to buy it automatically but, for the sake of this let's just pretend! I'm pretty sure this example will work! Hope it helped!

What is the ratio of cups to quarts in a carton of milk?

miss Akunina [59]

With some assistance they can pour 4 quarts into the gallon container to understand that 4 quarts are equal to 1 gallon. Since there are 2 pints in a quart, there are 8 pints in a gallon. Since there are 2 cups to a pint, there are 16 cups in a gallon.

There are 27 chocolates in a box, all identically shaped. There 4 are filled with nuts, 8 with caramel, and 15 are solid chocola

AlekseyPX

Answer:

Therefore the required probability is $\frac{30}{351}$ .

Step-by-step explanation:

Two events are dependents event if the occurrence of one of them has effect on the probability of the other.

If A and B are dependents,

then,

P(AB)=P(A)P(B).

Given that,

There are 27 chocolates in a box.

Number of nuts chocolates = 4

Number of caramel chocolates = 8

Number of solid chocolates= 15.

The probability of that a solid candy is drawn is

$=\frac{\textrm{Number of solid chocolate}}{\textrm{Total number of chocolate}}$

$=\frac{15}{27}$ .

After selecting a solid chocolate, the number of chocolate is= (27-1)=26.

The probability that a nut candy is drawn is

$=\frac{\textrm{Number of nut chocolate}}{\textrm{Total number of chocolate}}$

$=\frac{4}{26}$

$=\frac{2}{13}$

Therefore the required probability is

$=\frac{15}{27}\times\frac{2}{13}$

$=\frac{30}{351}$

What is 25+25-100+25+25

andrezito [222]

Answer: 0

Step-by-step explanation: when you add 25+25 it is equal to 50. when you subtract 100 from 50 it gives you -50. when you add 25+25= 50 so you add that -50 and 50 and it gives you zero (im not very good at explaining hope it helped)

The graph of f(x) = StartRoot x EndRoot is reflected across the x-axis and then across the y-axis to create the graph of functio

allsm [11]

Answer:

The true statements:

The only value that is in the domains of both functions is 0.

The range of g(x) is all values less than or equal to 0.

==================================

Step-by-step explanation:

See the attached figure:

As shown: f(x) = √x with blue color

When f(x) is reflected across the x-axis the result will be (-√x) with red color.

Then the is reflected result across the y-axis to create the graph of function g(x) = -√(-x) with green color.

Domain of f(x) = [0,∞) & Range of f(x) = [0,∞)

Domain of g(x) = (-∞,0] & Range of g(x) = (-∞,0]

So, according to previous, we will check the statements:

1) The functions have the same range. (Wrong)

2) The functions have the same domains. (Wrong)

3) The only value that is in the domains of both functions is 0. (True)

4) There are no values that are in the ranges of both functions. (Wrong)

5) The domain of g(x) is all values greater than or equal to 0. (Wrong)

6) The range of g(x) is all values less than or equal to 0. (True)
