I'm assuming the x's are multiplication signs so 

7(7) [ 67(7) +  28(7)(7) ] * 7 = 

7(7) [469 + 1372] * 7 

7(7) 1841 * 7

49 * 1841 * 7

90209 * 7

= 631463

You just have to plug in the V's for 7's.

* = multiplication sign.

If the brackets confuse you, they just are paratheses.

****10^-2****

0.0143053 Centimeters per Second or 1.43053 x 10-2 Centimeters per Second

the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

0.00001875

Your telling us what the variables equal, but no problem.

$84.50 - $12.25 - $17.85 - $15.45 = $38.95

Just to make it easier you would want to do 5 over 4. Then just divide both the denominator and numerator by 4 then you'll just get 0.8 over 1. So you'll have 0.8 salami for 1 oz.

Someone correct me if i'm wrong, i learned this in like 6th grade.

You reverse what your doing, you need to multiply to get 9.6 so you divide 9.6 by 1.2 so 9.6/1.2=b. So 8 would be B.
