Ninety two thousand and five hungered and forty two
All you have to do is multiply the l * w = Area
When you look at 26 ft and 15 ft, 21 ft and 10 ft, 29 ft and 18 ft, you'd know it wouldn't work since it's over 180.
So the dimensions of the ceiling are l = 20 ft; w = 9 ft
Answer:
-4
-10x+6
Step-by-step explanation:
I am going to assume the (Something)x2 means (Something). Then, the expression is 2-6
+4x-6x+9-3=-4-10x+6
To answer this, you can set up a system of equations. Solve for one of the variables and substitute this new equation into the 2nd equation.
2x + 5y = 243 - I'll solve this one for x.
8x + 6y = 538
2x + 5y = 243
2x = 243 - 5y
2 2
x = 121.5 - 2.5y ; substitute this in for x in the second equation
8x + 6y = 538
8 (121.5 - 2.5y) + 6y = 538
972 - 20y + 6y = 538
972 - 14y = 538
-972 -972
-14y = -434
-14 -14
y = 31
<u><em>The cost of a rod (y) is $31. </em></u>
x = 121.5 - 2.5y
x = 121.5 - 2.5 x 31
x = 44
<em><u>The cost of a reel(x) is $44.</u></em>
Answer:
Step-by-step explanation:
f(x) = 2x - 5
When x = -2,
f(-2) = 2*(-2) - 5 = - 4-5 = (-9)
When x = 0,
f(0) = 2*0 - 5 = -5
When x = 5,
f(5) = 2*5 - 5 = 10 - 5 = 5
x -2 0 5
y -9 -5 5
