Novay_Z [31]

Answer:

5x+8y

Step-by-step explanation:

We can first open the brackets by using the distrubitive propety.

2(x+4y)+3x

2x+8y+3x

Now we can combine like terms.

5x+8y.

I combined the 3x and the 2x. This works because imagined I have 3 of something then I got 2 more of that something I would now have 5 of that something.

Hoped this helped,

A truck enters a highway at 60 mph. A car enters the highway at the same place 11 minutes later and drives 74 mph in the same di
Crank

Answer:

Since speed is given in terms of "hours" we must convert 9 minutes to hours:

9 minutes = 9/60 hours = 3/20 hours

.

Let x = time (hours) it takes car to pass the truck

then

60(x + 3/20) = 69x

multiplying both sides by 20:

60(20x + 3) = 1380x

1200x + 180 = 1380x

180 = 180x

1 hour = x

Since BCDEF is regular, we know right away that x=\dfrac{360}5=72 because the measures of all exterior angles of any regular polygon add to 360 degrees; they are all of equal measure here, so we divide 360 by 5.

For the pentagon BCIHG, the same is true, which means we have the equation

\underbrace{72}_x+\underbrace{72}_{\angle_{ext}BCD}+\underbrace{90}_{\angle_{ext}CIH}+\underbrace{(180-y)}_{\angle_{ext}IHG}+\underbrace{68}_{\angle_{ext}HGB}=360\implies y=122

So x+y=194.

A store is having a sale on trail mix and jelly beans. For 5 pounds of trail mix and 6 pounds of jelly beans the total cost is $
inna [77]

The cost for each pound of trail mix and each pound of jelly is given below.

Step-by-step explanation:

Let t = cost/pound of trail mix

Let j = cost/pound of jelly beans

5t + 6j = 35

3t + 2j = 15  =  > 2j = 15 - 3t

5t + 3(15 - 3t) = 35

5t + 45 - 9t = 35

- 4t + 45 = 35

- 4t  =  - 10

4t = 10

t = 2.5

3(2.5) + 2j = 15

7.5 + 2j = 15

2j = 7.5

j = 3.75
