204 times .46 equals 93.84, to round of it would be 93.8
x is equal to 27.
In order to find the value of x, you have to use the average formula and solve for the missing variable. The mean formula is all of the numbers added together divided by the number of inputs.
(inputs added)/(number of inputs) = Average
(2 + 7 + x)/3 = 12 ----> Multiply by 3
9 + x = 36 ----> Subtract 9
x = 27
Correct answer; A right angle
3x^2+7x
18x^2-12x
-12x^3-8x^2
6x^3-18x^2+6x
Answer:
x=3 y=5/2
Step-by-step explanation:
1. 0.5x + y =4
2. 0.5x-y=-1
subtract the 2nd equation from the 1st
0.5x cancels out
2y = 5
y = 5/2
subs y = 5/2 into any one of the equations to find x
0.5x + 5/2 = 4
x = 3
subs to see if right:
(0.5 x 3) +5/2 = 4
(0.5 x 3) -5/2 = -1
