Answer:

  C, A, A

Step-by-step explanation:

In general, you ...

  • identify the coefficients of one of the variables
  • swap them, and negate one of them
  • multiply the corresponding equations by the "adjusted" coefficients.

__

In problem 1, the x-coefficients are 8 and 2. A common factor of 2 can be removed so that we're dealing with the numbers 4 and 1. Assuming we want to multiply one of the equations by 1, leaving it unchanged, the value we want to multiply by will be -4. After we swap the coefficients, that multiplier is associated with equation 2:

  multiply equation 2 by -4 . . . (eliminates x)

Likewise, the y-coefficients in problem 1 are -1 and 3. Again, if we want to multiply one of the equations by 1, leaving it unchanged, the coefficient we will change the sign of is -1 (becomes 1). After we swap the coefficients, the multiplier 3 is associated with equation 1:

  multiply equation 1 by 3 . . . (eliminates y)

These two choices are B and A, respectively, so the one that does NOT work for problem 1 is choice C, as indicated below.

__

The other problems are worked in a similar fashion.

Your mother saw a sale at the music store on tax-free weekend that advertised two CD’s for $15.95. Your mother said that you hav
Neko [114]

Answer:

20 CDs

Step-by-step explanation:

Assuming you can't buy 1 CD, you have to buy 2 CD's for 15.95, let's see how many 2CD-Batches we can buy with 60:

60/15.95 = 3.76 CD batches

We can't buy the fractional amount, so we have to buy "3" 2-CD-Batches.

Thus, we will have 3 * 2 = 6 CD's  now

Since we had 14 and now we buy 6, we will have

14 + 6 = 20 CDs now.

20 CDs

  • HJ = 23.5 in

\textsf{  \underline{\underline{Steps to solve the problem} }:}

Take HJ = a, GH = b and GJ = c

  • a = b + 2

  • c = a + b - 17

  • a + b + c = 73

put the value of a from equation 1 in equation 2

  • c = (b + 2) + b − 17

  • c = 2b − 15

now, put the value of a and c in equation 3

  • b + 2 + b + 2b − 15 = 73

  • 4b − 13 = 73

  • 4b = 86

  • b = 21.5 in

Now, we need to find HJ (a)

  • a = b + 2

  • a = 21.5 + 2

  • a = 23.5 in

{ \qquad \large \sf {Conclusion} :}

  • HJ = 23.5 in
