Answer:

a) 4x - 8y

b) 4 × x - 8 × y

c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication

Step-by-step explanation:

a) start with the parentheses

1/3 (6x - 12y)

multiply 6x and -12y by (1/3)

2x - 4y

so now the equation is 5x -3x -4y + 2x -4y

add together the like terms

5x -3x + 2x = 4x

-4y -4y = -8y

so we have 4x - 8y

b) im not good with factored form but i believe this is right

take 4x and separate them by turning it into 4 × x and same for -8y turn it into -8 × y

c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication

im not sure how to prove them equal to the original expression i dont really remember that but i hope this helped

John stands 150 meters from a water tower and sights the top at an angle of elevation of 36º. If John's eyes are 2 meters above
horsena [70]

Answer:

The height of tower DB=111\ meters.

Step-by-step explanation:

Diagram of the given scenario is shown below.

Given that,

Distance between John and tower is  CE=150 \ meters.

Angle of elevation to the top of the tower is \angle DEC=36°.

Height of John is  CB=2\ meters.

To Find: Height of the tower DB.

So,

In triangle ΔDCE,

                    Tan(∠DEC)= \frac{DC}{CE}

                    Tan (36)= \frac{DC}{150}

                     DC= tan(36)\times 150

                     DC=108.98\ meters

Now,

To calculate the height of tower we have

                    DB=DC+CB

                    DB=108.98+2

                    DB=110.98\ meters ≈ 111 \ meters

Therefore,

The height of tower DB=111\ meters.

Joey Chestnut is trying to break his own world record for eating the most hot dogs and buns in 10 minutes. He needs to eat more
mr Goodwill [35]
73 (because you want more than 72 to break the record) - 10 = 63
63/9 ( the amount of minutes left) = 7

Joey would have to eat at least 7 hot dogs each minute to break his record.

x+10 > 72

hope this helps
