Answer:

\Huge\boxed{30}

Step-by-step explanation:

Remember to use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) from left to right.

First, do parenthesis.

6(3-5)+7(4+2)

(3-5)=-2

6(-2)+7(4+2)

(4+2)=6

6(-2)+7*6

Multiply.

6(-2)=-12

-12+7*6

7*6=42

-12+42

Add or subtract.

-12+42=30

30, which is our answer.

Which values of x are solutions of the equation below
Mandarinka [93]

Answer:

x = 3.3 and -0.3

Step-by-step explanation:

Given the expression

1/x-4 + x/x-2=2/x^2-6x+8

Find the LCM

x-2+x(x-4)/(x-4)(x-2) = 2/x^2-6x+8

Since the denominator, are the same they cancels out

x +1 + x(x-4) = 2

x+1 + x²-4x = 2

x²-3x + 1 - 2 = 0

x² - 3x - 1 = 0

Factorize

x =3±√9+4/2

x =3±√13/2

x = 3±3.6/2

x= 6.6/2 and -0.6/2

x = 3.3 and -0.3

Caroline has a movie card worth $75 that her grandfather gave to her for her birthday. After seeing her first movie, the card’s
faust18 [17]

Answer:

f(m) = 75-8m

Step-by-step explanation:

She began with $75.  After the first movie, she had $67 remaining; this means she spent

75-67 = $8

After the second movie, she had $59 remaining; she spent

67-59 = $8

After the third movie, she had $51 remaining; she spent

59-51 = $8

Each movie costs $8.  Letting m represent the number of movies, this gives us 8m.

Since she is spending money, we subtract this from the original amount, $75; this gives us

f(m) = 75-8m
