Add the two rows together
3x = 12
Solve for x in the above equation
x = 4
Substitute x = 4 into any of the two equations above. Let's choose the first one; 2x - y = 6
2 × 4 - y = 6
Solve for y in the above equation
y = 2
Thus,
<u>x = 4</u>
<u>y = 2</u>
Answer:75, percentage increased by 41% (of its value = 105.75
Step-by-step explanation:
Answer:
WT = 34
Step-by-step explanation:
The ultimate goal here to pinpoint what x is equivalent to. In a rectangle we know that the diagonals are congruent as well as the fact that they bisect each other. This means cutting in half. Using this knowledge we know VW = 9x - 11 is half of SU = 16x - 12.
Step One: Multiply 9x - 11 by 2.
2(9x - 11) = 18x - 22
Step Two: Set up your equation
18x - 22 = 16x - 12
Step Three: Solve for x
18x - 22 = 16x - 12
2x - 22 = -12
2x = 10
x = 5
Step Four: Substitute to check your work
16(5) - 12 = 68
9(5) - 11 = 34
Again, since the diagonals of a rectangle bisect each other VW = WT.
34 is half of 68 proving our findings.
Let a, b, c represent the numbers of subscribers who watched 1, 2, and 3 videos, respectively.
.. a +b +c = 312 . . . . . . . there are 312 subscribers, total
.. a +2b +3c = 740 . . . . there were 740 total views
Subtract double the first equation from the second.
.. (a +2b +3c) -2(a +b +c) = (740) -2(312)
.. c -a = 740 -624 = 116
116 more people watched all three videos than watched one video.
