2(2 - 2x) = 4
Distribute (multiply) 2 inside the parentheses.
4 - 4x = 4
Subtract 4 from both sides.
-4x = 0
DIvide both sides by -4.
x = 0
x is 0 because anything divided by 0 (0/-4) equals 0.
Cross Multiply by 'x - 5'
Hence
y(x - 5) = 4 -3x
xy - 5y = 4 - 3x
Move all the terms containing an 'x' to one side of the equals and all the others to the opposite side.
xy + 3x = 4 + 5y
Factor out 'x'
x(y + 3) = 4 + 5y
'Cross' divide by 'y + 3'
x = ( 4 + 5y) / (y + 3 )
'x' is now the subject.
Answer:
x = 6
Step-by-step explanation:
The median is half the sum of the parallel bases , then
= 13 ( multiply both sides by 2 to clear the fraction )
12x - 46 = 26 ( add 46 to both sides )
12x = 72 ( divide both sides by 12 )
x = 6
When we add 82.545 and 128.580 we get a total of 211.125, now the closest number to the answer is B. 211.125
<h3>Addition of Numbers</h3>
Given Data
Number one = 82.545
Number two = 128.580
Total Number = 82.545 + 128.580

Answer:
a
Step-by-step explanation:
lets represent the black beads as the letter b and the Gray beads as g
the overall formula would be: g+2
so the answer would be a because 6 to get to 8 is 2 which is part of the formula written above ^
