On a trip, the fare was 75¢ for each adult and 50¢ for each child. If 20 passengers paid $12.00, how many adults and children went?Which of the following equations could not be used to solve the problem?
A) 75x+50(20-x)=1200
B) 75(20 - x) + 50x = 1200
C) 75x + 50x = 20(1200)

Answers

Answer 1
Answer: There are two cases in which this question can be answered. In our first case, let the number of adults be x and that of the children, 20 - x. On the second case, we let x be the number of children and 20 - x for adults. In the first case, the total fare may be expressed as 50x + 75 (20 - x) = 1200 and 75x + 50 (20 - x) = 1200. The expression in the first case is in letter b and the second case in letter a. Therefore, the answer for this item is letter c.

Represent the polynomial x2 – 16 geometrically using algebra tiles. The number of zero pairs that will be added to the board is24 816 . The equivalent factored form of x2 – 16 is(x – 16)(x + 1)(x – 4)(x – 4)(x + 4)(x + 4)(x – 4)(x + 4) .

Answers

Answer:

Fourth option: (x-4)(x+4)

Step-by-step explanation:

x^2-16

Using a^2-b^2=(a-b)(a+b) with:

a^2=x^2→sqrt(a^2)=sqrt(x^2)→a=x

b^2=16→sqrt(b^2)=sqrt(16)→b=4

Then:

x^2-16=(x-4)(x+4)

Answer:

The number of zero pairs that will be added to the board is

✔ 4

The equivalent factored form of x2 – 16 is

✔ (x – 4)(x + 4) (D)

If a slope of a line is 2/0 is it 0 or undefined?

Answers

It's undefined. When you have a slope as a fraction, it's "rise over run". The line rises two but runs zero, so it's a vertical line. If it were 0/2, that would be a horizontal line, aka 0 slope

Answer: Undefined

It is impossible to divide by zero, so it is undefined.

G(x)= 8x+2 g(?) = -62

Answers

Answer:

x = -8

Step-by-step explanation:

g(x)= 8x+2

Let g(x) = -62

-62 = 8x+2

Subtract 2 from each side

-62-2 = 8x+2-2

-64 = 8x

Divide each side by 8

-64/8 = 8x/8

-8 = x
the answer is x= -8.
