Look at the picture.
We have the equation (1) 12x + 4y = 40.
We know, the sum of the acute angles in a right triangle is 90°.
Therefore we have the equation (2) (12x + 4y) + (17x - y) = 90
Substitute (1) to (2):
40 + 17x - y = 90 <em>subtract 40 from both sides</em>
17x - y = 50 (3)
We have the system of equations:
Substitute the value of x to (3)
Answer: x = 3 and y = 1.
Answer:
Step-by-step explanation:
we know that
In a parallelogram the diagonals bisect each other
The figure XYZW is a parallelogram
so
VW=VY
VX=VZ
<em>Find the value of b</em>
VW=VY
substitute the given values
solve for b
Find the length of YW
----> by addition segment postulate
substitute the value of b
Answer: X=34/137 I think
Step-by-step explanation:
The 2nd number position after the decimal is always the hundredth position, so we will work from there. To round a number, you must examine the number that comes after the number you are trying to round. In this case the number you are trying to round is the 8 so we have to look at the 2. because the two is a number less than 5, the 8 will remain an 8 and your rounded answer is 4.08. If that two had been a number greater than 5 than the 8 would have become a 9 and your answer would have been 4.09. When rounding always remember: "5 to 9, up the line; 0 to 4, down to the floor."
