Do you mean x - 2 divided by 6 or x -2/6 I think you probably mean (x-2/6 If that is correct, then multiply each part by 6 and then add 2 to each part. That will leave x in the middle. I call these the "sandwich problem" because x is sandwiched betweent the lower and...

There are 36 possible combinations when you roll a pair of dice. Figure out how many doubles you would have and subtract that from the 36 possible outcomes.

**Math**

a = b (-d-c)/cd Multiply cd times both sides then distribute the b. acd = -bd-bc add bc to both sides: acd+bc = -bd factor out the c c(ad+b) = -bd Divide both sides by (ad+b) to solve for c.

13 and add 8 = 21 add 8 = 30 and add 8 =38. So, 32 falls between 2 and 3 standard deviations. 40 - 13 = 27, 32 falls within one standard deviation. February is more likely. You could also take 32 -13 =19 and divide by 8 to get z = 2.375 32-40 = -8 divided by 13 to get z = -....

Write in y = mx+b form. 10y = -2x + 10 y = -1/5 (x) + 1 If x = 5, y = 0 If x = 3, y = -3/5 + 1 or 2/5 If x decreases by 2, then y decreases by 2/5 of a unit.

**MAth**

You have to convert feet to centimeters here. change 102 feet to inches by multiplying by 12. Then convert inches to centimeters. 1 inch = about 2.5 cm, so divide the inches by 2.5 to get centimeters. Then take a ratio with the 12 cm. I think the scale is 40:1.

**MATH**

You have to subtract 63 from both sides of the equation set = 0. then factor and set each factor equal to zero to solve for x.
