Answer:1000
Step-by-step explanation:
System of Equations
Let:
x = number of people that can be seated at a table
y = number of people that can be seated at a booth
The first plan consists of 23 tables and 10 booths and then 228 people could be seated, thus:
23x + 10y = 228
The second plan consists of 12 tables and 12 booths and that way 180 people could be seated, thus:
12x + 12y = 180
The method of elimination requires equating the coefficients of one variable and eliminating it by adding the equations.
Multiply the first equation by 12:
276x + 120y = 2736
Multiply the second equation by -23:
-276x - 276y = -4140
Add the last two equations (the variable x cancels out):
120y - 276y = 2736 - 4140
Simplifying:
-156y = -1404
Dividing by -156:
y = -1404/(-156)
y = 9
Substitute this value in the first equation:
23x + 10(9) = 228
Operate:
23x + 90 = 228
Subtract 90:
23x = 138
Divide by 23:
x = 138/23
x = 6
Every table can seat 6 people, and every booth can seat 9 people
The correct answer is: 0.7, 0.6, and 3/10
3/10 converted to a decimal is 0.3
The answer is -5 because :
16-20= -4
-4- -8= 4 bc when the minuses are next to each other it's like you are adding so -4+8=4
4-9=-5
Answer -5
Answer:
p = 14/4
Step-by-step explanation:
-4p+9=-5
-4p = -14
p = 14/4
