–x + y = –3 (a)
3x + 2y = 9 (b)

Lt's eliminate y , by multiplying a) by -2

-2(–x + y) = -2(–3) → +2x - 2y = +6 (c). Now add (c) to (b)

+2x - 2y = +6 (c).
3x + 2y = 9 (b)
-----------  --------
5x + 0   = 15     and x = 15/5   and x = 3
To find y, plugin the value of x in any of the equation, sat (a):
–x + y = –3 (a) → -3 + y = -3; y = -3+3 → y = 0

So the solution is (3,0) Answer C

Lemon drops and jelly beans are mixed to make a 100 pound mix. if the lemon drops cost $1.90 per pound and jelly beans cost $1.2
vladimir1956 [14]

L = lemon drops

J = jelly beans

L +J = 100

L=100-J

1.90L + 1.20J=1.48*100

1.90(100-j) +1.20J =148

190-1.90J+1.20J=148

190-0.7J=148

-0.7J=-42

J = 60

L=100-60 = 40


40 pounds of Lemon Drops are needed

What are the mean and the mode of the following set of data: 5, 12, 1, 5, 7
Alika [10]
Mean: so basically you add up all the numbers (5+12+1+5+7=30) and divide the sum (30) with how many numbers there are (5) so 30/5=6

mode: mode is numbers repeated, since there are two 5's it is the mode (you may also have multiple modes)
