Our inequality looks like this:
2(x+6)≤52
Using the Distributive Property, we have
2*x + 2*6 ≤52
2x+12≤52
Cancel the 12 by subtracting from both sides:
2x+12-12≤52-12
2x≤40
Divide both sides by 2:
2x/2 ≤ 40/2
x≤20
x cannot be any more than 20 to satisfy this inequality.
Answer:
27
Step-by-step explanation:
because 6×4 is 24 and 24+3 =27
Answer:
When the number of guests is 0, the cost would be $450.
Step-by-step explanation:
We have been given an equation
, which models the relation between the cost in dollars, C, of the banquet and the number of guests, g.
We can see that our given equation in slope-intercept form of equation
, where, m represents slope of line and b represents y-intercept or initial value.
We can see that slope for our given equation is 28 and the C-intercept is 450.
The C-intercept tells us that when there are 0 guests in the banquet, the cost would be $450.
Answer:
Step-by-step explanation:
I'm assuming you are solving this system for x, y, and z. Do it this way:
Combine the first 2 equations and the second 2 equations and eliminate the y's. The first 2 equations:
x + y + z = 3
x - y + z = 2
which solves to
2x + 2z = 5
The second 2 equations:
x - y + z = 2
x + y - z = 1
which solves to
2x = 3 so
x = 3/2 or 1.5
Now sub that x value into the bold equation above to get:
2(1.5) + 2z = 5 and
3 + 2z = 5 and
2z = 2 so
z = 1
Now we plug back in to solve for y:
1.5 + y + 1 = 3 and
2.5 + y = 3 so
y = .5
The solution set then is (1.5, .5, 1) or in fraction form:

8) 1.40 per ounce
9) 3.14 for 1 pound
10) K = t/c
Hope all this helps you out.
