Answer:
-20/7
Step-by-step explanation:
5m +72 = -2m + 52
5m + 2m = 52-72
7m = -20
m = -20/7
Answer:
Step-by-step explanation:
The triangle is recognizable as a 30°-60°-90° right triangle, which has side length ratios ...
1 : √3 : 2
Side x is thus twice the length of short side 4, so x = 8.
Side y is √3 times the length of short side x-6 = 2, so y = 2√3.
_____
If you don't happen to recognize the triangle dimensions, you can find x and y using the Pythagorean theorem.
x = √(4² +(4√3)²) = √64 = 8
y = √(4² -2²) = √12 = 2√3
Answer:
X=54
Step-by-step explanation:
180-126=54
the line has to be 180 so it has to be able to add to 126 and equal 180.
To find the price after the discount the equation would be 39..98x.30which would equal 11.99. subtract that from the price before the discount and you get $27.99. thats your first answer. to find the second answer you would do 23.99 divided by 11.99 (the diacount from the first equation) to get the discount rate of 2% so your final answers are $27.99 and 2%
