Ben drinks tea at an incredible rate. He drinks 3\
123 2 1 ​

Answers

Answer:

He drinks 5 1/4 liters of tea in one hour.

Step-by-step explanation:

Ben drinks 3 1/2 liters of tea every 40 minutes.

This means that he would drink 1 3/4 of tea every 20 minutes (divide both sides by 2).

Now, let's multiply each side by 3.

1.75 * 3 = 5.25 (aka 5 1/4)

20 * 3 = 60 minutes (an hour)

What is the expression [tex]x^2+14x+40[/tex] in factored form?

Answers

Answer:

b

Step-by-step explanation:

since x is squared, you would put that into both parenthesis, so you should have (x)(x) right now

then you need to find factors of 40 that add to 14

factors of 40: 40 and 1, 20, and 2, 4 and 10, 5 and 8

4 and 10 multiply to equal 40 and add to equal 14

put each factor into a parenthesis

so now you should have (x+10) (x+4)

side note: if the number 40 was negative then one of the factors would have to be negative, this would result in (x+10) (x-4) or (x-10) (x+4)

Which ordered pair is not a solution to this system?

Answers

Answer:

A (2,1)

[tex]x + y > 3 \\ x + 2y > 5 \\ \\ a)2 + 1 > 3 \: wrong \\ 2 + 2(1) > 5 \: wrong \\ \\ [/tex]

So, right off the bat, you can tell that the ordered pair (2,1) is most definitely NOT the solution to this system.

Combine like terms

6 -8x = -3x+11

Add 8x to each side

6-8x +8x = -3x+8x +11

6 = 5x+11

Subtract 11 from each side

6-11 = 5x+11-11

-5 =5x

Divide each side by 5

-5/5 = 5x/5

Josie makes fruit punch by mixing fruit juice and lemonade in the ratio 3:4. She needs to make 49 liters of punch for the party. How much of each ingredient does she need

Answers

She would need 21 liters of fruit juice and 28 liters of lemonade.

Answer:

juice = 21lemonade = 28

Step-by-step explanation:

given:

ratio of juice and lemonade = 3:4

She needs to make 49 liters of punch for the party.

find:

How much of each ingredient does she need

solution:

add the ratio 3 + 4 = 7

total punch divide by the total ratio

49 / 7 = 7 (coefficient)

juice           3 x 7 = 21

lemonade  4 x 7 = 28

                   total = 49

Find the equation of the line that contains the points (6,3) and (9,4) Write the equation in the form y=mx+b HELP ASAP

Answers

Answer:

y = 1/3x + 1

Step-by-step explanation:

find the slope by using y2-y1/x2-x1

4-3/9-6

1/3.  slope = 1/3 = m

2. plug the values into the equation to find y-int. You can use whichever point is given to you

I'll use (6,3)

y = mx + b

3 = 1/3(6)+b

1/3(6)=2

3 = 2 + b

3. subtract 2 from both sides and you get b

b = 1

So, the equation of the line would be

y = 1/3x + 1
