X = <span>width
2x-3 = </span><span>length
</span>

width = 6.5 m
length = 2x-3 = 2*6.5 - 3 = 10 m
<span>B) A key chain can hold 3 keys. If there are a total of 12 keys, how many key chains are there?</span>
Answer:
m=#miles
so 130= .5m+30
subtract 30 from each side
100$= .5m than divide .5 to isolate m
m= 200
Step-by-step explanation:
Answer:
x=15√2 y=90 degrees.
Step-by-step explanation:
Thanks to the Pythagorean Theorem we know that with any right triangle, A^2+B^2=C^2. In this case we can use 15^2+15^2=sqrt of 450. The square root of 450 is 15 times the square root of 2. Thus x=15√2. Now we need to find y. All angles in a triangle add up to 180 so if we have 45+45+y=180 then y=90.
The answer is F.) 0= x^2 - 15x + 54
