Your answer will be A, 20 hours to take the crew to complete a building with 200 windows
Start with the given 4x + 1 = 6x - 2.
Combining like terms, we get 3 = 2x, from which we later get x = 3/2.
Where the question mark appears, write, "Reverse the order of 3/2 = x to obtain x = 3/2."
Represent 24 as a sum of two numbers, first number from first die and second number from second die.
24=19+5=18+6=17+7=16+8=14+10=13+11=12+12=11+13=10+14=9+15=8+16=7+17=6+18=5+19=4+20 (the sums 15+9 and 20+4 are absent, because there aren't numbers: 20 on the first die and number 9 on the second die). Totally, you receive 15 different representations of 24.

(here
means that you have 20 possibilities to roll first number or blank face on the first die and 20 possibilities to roll number or blank face on the second die).

Best Answer: lets sub and find out...
y = 11x
(0,11)
11 = 11(0)
11 = 0 (incorrect)
not the first one
(1,12)
12 = 11(1)
12 = 11 (incorrect)
not the second one
(2,22)
22 = 11(2)
22 = 22 (correct)
Here it is :)
let me go ahead and check the last one as well...
(11,1)
1 = 11(11)
1 = 121 (incorrect)
Your answer is C. (2,22)
When you get problems like these, just sub your set of points (x,y) into the equation to see which one satisfies the equation.
