Answer:
(a) 180°
(b) 180°
(c) substitution property
(d) m∠3
(e) ∠3
Step-by-step explanation:
Definition: Two angles are supplementary if they add up to 180°
Proof:
By definition of supplementary angles, m∠1 + m∠2 = 180° (a) {∠1 and ∠2 are supplementary - given}
and m∠2 + m∠3 = 180° (b) {∠2 and ∠3 are supplementary - given}
Then, m∠1 + m∠2 = m∠2 + m∠3 by the substitution property (c)
Subtract m∠2 from each side. You get m∠1 = m∠3 (d)
or ∠1 ≅ ∠3 (e)
The total number of gallons of paint needed for the big room is 3x and the number of gallons of paint needed for the small room is 2y.
3x + 2y = 16
Given the sizes of the room, the relation should be that,
x = 2y
Solving the equation,
3(2y) + 2y = 16
y = 2
Therefore x is equal to 4 gallons.
With the condition that only the bigger room is painted, the number of gallons of paint used should be 12 gallons and what is left should be 4 gallons.
Answer:
1/15
Step-by-step explanation:
Dividing a fraction can sometimes be seen as multiplying it by another fraction.
So instead of doing (1/5)/3 we can write it like this:
1/5 * 1/3
And since multiplying something by one third is equivalent to dividing it by three, nothing has really changed.
So now we can multiply the fractions.
First we'll take the numerator (the number above the line) of 1/5 and multiply it by the numerator or 1/3.
1 * 1 = 1
Then we do the same for the two denominators (the numbers <em>below</em> the line)
5 * 3 = 15
So now we've turned 1/3 * 1/5 into: (1*1)/(3*5),
Then simplified it to:
1/15
