Answer:
Vertical Angles are equal. Therefore:
(7x -4) = (6x +8)
x = 12
answer is D
Step-by-step explanation:
Since the problem gives the number of values of how far away each Eaton and Wellington are from Baxter, you can add both of the miles together to get the total distance from Eaton to Wellington.
42 1/2+37 4/5=
Find the common denominator for both of them.
42 5/10 + 37 8/10=
Answer: 80 3/10 miles from each other
X + y > = 36 (thats greater then or equal)
2x + 0.6y < 40
Answer:
9 + x
Step-by-step explanation:
The area of a rectangle is length times width.
A = lw
We know the area is 81 - x^2 and the width is 9 - x, so plug them in.
81 - x^2 = 9-x * w
81 - x^2 is a difference of squares in the form a^2 - b^2 = (a-b)(a+b), so we know the width must be 9 + x.
Test it to be sure:
(9 + x)(9 - x)
81 + 9x - 9x -x^2 = 81 - x^2
It works!
