Answer:
Step-by-step explanation:
2c+12t=105, and 5c+3t=33, subtracting 4 times the second from the first gives you
2c+12t-20c-12t=105-132
-18c=-27 dividing each side by -18
c=1.5, making 2c+12t=105 become
2(1.5)+12t=105
12t=102
t=8.5
So each chair costs $1.50 and each table costs $8.50
Answer:
y4.5
Step-by-step explanation:
Answer:
2x + y = 12 & x = 9 - 2y --- (x = 5, y = 2)
x + 3y = 16 & 2x - y = 11 --- (x = 7, y = 3)
y = 11 - 2x & 4x - 3y = -13 --- (x = 2, y = 7)
2x + y = 11 & x - 2y = -7 --- (x = 3, y = 5)
Step-by-step explanation:
Answer:
32%, 8/25
Step-by-step explanation:
Since we are looking under the category of buttons, only 1 of the 3 options fit the description. 32 have buttons but no zips. All the others are either just zip or neither of them.
This means out of 100, only 32 have buttons
32/100 or 32%
We can simply 32/100 to 8/25
