Mariana [72]

Answer:

.55

Step-by-step explanation:

You want to shorten the decimal to just to two after the decimal point. If so for example, .443 would be shortened to .44, but if the third number is 5 and up, you would take the second number after the decimal point and add 1. For example,

.446 would round up to .44, which is why .5524 would round to .55

I cant solve this help –8x + 15 < 71
Ratling [72]

Answer:

x > -7

Step-by-step explanation:

Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

First, subtract 15 from both sides:

-8x + 15 (-15) < 71 (-15)

-8x < 71 - 15

-8x < 56

Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:

(-8x)/-8 < (56)/-8

x < (56)/-8

x > -7

x > -7 is your answer.

Jemina flips a disc of the type shown below: A disc with two layers is shown. The top layer is shaded in a darker shade of gray,
Yakvenalex [24]
The probability is just 1/2 that the disc will result with the white side landing up.

There are two sides to the disc. If they are equally likely to happen, then the chance of either side is 1/2. It does not matter which number the flip is.

Need help<br><br><br>y+3=6(x+2)-3
olga_2 [115]

<u>Slope-Intercept:</u>

y + 3 = 6(x + 2) - 3

y + 3 = 6x + 12 - 3

<u>     -3 </u>   <u>             -3 </u>

y        = 6x + 12

<u>Standard:</u>

       y = 6x + 12

<u>-6x </u>       <u>-6x        </u>

-6x + y = 12

-1(-6x + y = 12)

  6x - y = -12

<u>Graph:</u>

y = 6x + 12

      ↓      ↓

      ↓     y-intercept

   slope

Start by graphing the y-intercept: (0, 12)

Then count the rise (up 6) and the run (right 1) from the y-intercept: (1, 18)

or

count the rise (down 6) and the run (left 1) from the y-intercept: (-1, 6)
