Answer:
I’m assuming you want which is cheaper so
9+.11= 9.11 that is plan a
29+.009=29.009
Step-by-step explanation:
Answer:
y = -7
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Angle M is vertical to K, it is congruent. Angle E and C are corresponding angles to Angle M, which are angles positioned in the same direction. Angle E and C are congruent because they are the congruent to Angle M and Angle M is congruent to Angle K.
Let x be the amount of Columbian coffee in the mixture and y the amount of Sumatra coffee in the mixture, then
x + y = 1 . . . (1)
9.25x + 14.25y = 12.50 . . . (2)
(1) x 9.25 => 9.25x + 9.25y = 9.25 . . . (3)
(2) - (3) => 5y = 3.25 => y = 3.25/5 = 0.65
From (1), x + 0.65 = 1 => x = 1 - 0.65 = 0.35
1 pound of the mixture contains 0.35 Columbian coffee and 0.65 Sumatra coffee
Therefore, 12 pounds of the mixture will contain 0.35 x 12 = 4.2 pounds of Columbian coffee and 0.65 x 12 = 7.8 pounds of Sumatra coffee
Let x = price for each cake and y = price of each pie in dollars.
We can get two equations out of the data. One from the Friday set, the other from the Saturday set.
Then, we subtract both equations. The difference would be:
-20y = -160
y = -160 ÷ -20
y = $8
Finally, we substitute y to any of the equations. Suppose, we use equation 1:
30x + 20(8) = 460
30x = 460 - 160
30x = 300
x = 300 ÷ 30
x = $10
Therefore, the cost for each cake and pie is $10 and $8, respectively.
