Answer:
The measure of the two supplementary angles are 65 degrees and 115 degrees.
Step-by-step explanation:
The sum of supplementary angles is equal to 180 degrees. Let x and y are two angles such that,
According to given condition,
One supplementary angle is 15 degrees less than twice the other, it means,
Putting the value of x from above equation in equation (1),
Now put the value of y in equation (1), so,
So, the measure of the two supplementary angles are 65 degrees and 115 degrees.
Decimal for 3/5= 6/10 = 0.6
R is 4 if I'm wrong sorry
Hi there!
Using the secret code that is used in math problems(:P), we derive the equation 3x+1=17-x.
3x+1=17-x
4x+1=16
4x=16
x=4

Answer:
Marc's age is 12
Step-by-step explanation:
Let
x ----> Marc's age
y ---> Tony's age
z ---> Ben's age
we know that
the sum of their ages is 40
so
-----> equation A
Marc is half as old as Tony
so
----> equation B
Marc is three times as old as Ben
so
----> equation C
substitute equation B and equation C in equation A
solve for x
therefore
Marc's age is 12
