a.) 12x - 3y = -33
10x - 6y = -38

b.) -4x - 9y = -21
-2x - 7y = 27

c.) 4x + 3y = 5
10x + 5y = -1

d.) 2x- 4y = -16
4x - 4y = 44

You have 37 coins that are nickels, dimes, and pennies. the total value of the coins is $1.55. there are twice as many pennies as dimes. find the number of each type of coin in the bank.

Abby is collecting rainfall data. she finds that one value of the data set is a high-value outlier. which statement must be true? abby will use a different formula for calculating the standard deviation. the outlier will increase the standard deviation of the data set. the spread of the graph of the data will not change. abby will not use the mean when calculating the standard deviation.
