All you have to do is follow the steps!

Think of a number - n

Add 10 - n + 10

Add the number you were thinking of - n + 10 + n

Divide by 2 - (n + 10 + n) / 2

Subtract 5 - ((n + 10 + n) / 2) -5

It may look hard, but its not as hard as you think. All you need to do is follow the steps!

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

The sum of two numbers is 40 and their difference is 6.5, what is their product? show work please
Finger [1]
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

One angle of a right triangle measures 75°. What is the measure of the other acute angle?
Natalija [7]

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
