NeTakaya

Answer:

B, D, C, A

Step-by-step explanation:

The question is asking to put the photographers into least to greast.

For the best case, I suggest you change them into decimals and put them in order.

Photgrapher A: 2/5 = 0.4 = 40%

Photographer B: 4% = 0.04 = 4%

Photographer C: 0.29 = 29%

Photographer D: 27/100 = 0.27 = 27%

Now put them into least to greatest.

Photographer B, Photographer D, Photographer C, And Photographer A

From the set {80, 19, 11}, use substitution to determine which value of x makes the equation true. 8x = 88 A. none of these B. 1
mel-nik [20]

Answer:

  C.  11

Step-by-step explanation:

Substituting, we have ...

  8{80, 19, 11} ?= 88

  {640, 152, 88} ?= 88

The value from the set that makes the equation true is x = 11.

_____

<em>Alternate methods of solution (other than substitution)</em>

It can be easier to make use of your knowledge of factoring:

  8x = 8·11

  x = 11

Or to make use of your knowledge of numbers (place value):

  8·10 = 80

so x will not be very different from 10.
