Answer: 7x+7

Step-by-step explanation:1

Eliminate redundant parentheses

(5x+10)+(2x-3)

(5x+10)+(2x−3)

5x+10+2x-3

5x+10+2x−3

2

Subtract the numbers

5x+10+2x−3

5x+7+2x

Combine like terms

5x+7+2x

7x+7

Solution

7x+7

Step-by-step explanation:

2x-5=7

add 5 on both sides:

2x-5+5=7+5

2x=12

divide both sides by 2

2x/2=12/2

x=6

the drinks are 10

, burgers are 5 and each of the fries are 1. Since there is one of each, it will be like this 10+5+1

Answer:

soda = 10

burger = 5

fri = 2

5 + 2 x 10 = 25

Step-by-step explanation: its 25 cuz its 25

Answer:

50°

Step-by-step explanation:

In an inscribed quadrilateral, the opposite angles are supplementary (angle sum = 180).

2x + 80 = 180

2x = 100

x = 50

The value of x of  O is circumscribed about quadrilateral ABCD is 50degrees

According to the circle geometry given, the sum of the opposite sides of the quadrilateral is 180 degrees.

Setting up the required equation;

2x + 80 = 180
2x = 180 - 80
2x = 100

Divide btoh sides by 2

2x/2 = 100/2

x =50

Hence the value of x of  O is circumscribed about quadrilateral ABCD is 50degrees

Answer:

  about 15.5%

Step-by-step explanation:

The number of foxes in the forest can be modeled by the exponential equation ...

  f = a·b^t

where a is the initial number, and b is the growth factor per year for t years. The growth factor is 1 more than the growth rate (r), so we can put numbers in this formula to get ...

  40 = 30·(1 +r)^2

  4/3 = (1 +r)^2 . . . . . . divide by 30

  1 +r = √(4/3) . . . . . .  take the square root

  r = √(4/3) -1 ≈ 0.1547 ≈ 15.5%

The annual percentage growth in the fox population is about 15.5%.

Answer:

  x = 6

Step-by-step explanation:

Angles AFB and CFE are vertical angles, so have the same measure. That means arc AB has the same measure of arc CE. The latter arc is 27° more than arc DE, which is 90°. So, we have ...

  arc AB = arc CE

  21x -9 = 90 +27

  21x = 126 . . . . . . add 9, collect terms

  x = 6 . . . . . . . divide by 21

Answer:

  A.  15.250

Step-by-step explanation:

The applicable trig function is the cosine function:

  Cos = Adjacent/Hypotenuse

  cos(57°) = y/28

  y = 28×cos(57°) ≈ 15.24989

  y ≈ 15.250 . . . . matches choice A

_____

Additional comment

From your knowledge of "special" triangles, you know that y would be 14 if the angle were 60°. Of course, the length must be shorter than 28, so answer choices B and C are immediately eliminated. The fact that the length is closer to half of 28 than it is to 28 makes choice A look like a pretty good guess.

Answer:

There are 79,800 ways in which this is possible.

Step-by-step explanation:

The order in which the students are chosen is important(due to different roles), which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this question:

2 sophomores from a set of 20.

2 freshmen from a set of 15. So

[tex]P_{20,2}*P_{15,2} = \frac{20!}{18!}*\frac{15!}{13!} = 20*19*15*14 = 79800[/tex]

There are 79,800 ways in which this is possible.

Answer:

Answer given below

Step-by-step explanation:

When we calculate the LCM, you get it as 6.

So both the fractions should have a denominator 6.

For that, in 2/3 we should multiply both numerator and denominator with 2 so that denominator becomes 6.

When we convert to like fraction, 2/3 becomes 4/6.

Now both the fractions have common denominator
