the first customer paid $12 for 14 postcards and 5 large envelopes.
the second customer paid $24.80 for 10 postcards and 15 large envelopes.
•
what was the cost in dollars of each large envelope?
a $1.42 c $1.15
b $0.35 d $0.63

51-50

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.

sorry but i cant draw that

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
