I believe the correct answer from the choices listed above is the third option. All of the following proportions are equivalent except <span>a/d=c/b.
</span><span>a/b=c/d
b/a=d/c => a/b = c/d
a/d=c/b not equal to </span>a/b = c/d<span>
a/c=b/d => </span>a/b = c/d
i don’t know your choices but this is the answer i got: -2(9x-10)
Let b>a,
a+b=40 so we can say a=40-b
We are told that b-a=6.5, using a found above in the equation gives us:
b-(40-b)=6.5
b-40+b=6.5
2b-40=6.5
2b=46.5
b=23.25, and since a=40-b
a=40-23.25
a=16.75
So a=16.75 and b=23.25
check...
16.75+23.25=40, 40=40
23.25-16.75=6.5, 6.5=6.5
Answer: C
Reasoning: there are 3 continuous blocks that are added to a changing number or n, in other words it can be represented as n + 3
Answer:
15
Step-by-step explanation:
A right angle is 90 degrees
The given angle is 75
90 + x + 75 = 180 (all three angles always add to 180 degrees)
165 + x = 180
180-165 = 15
