Answer: m = 25</h3>
====================================================
Work Shown:
Triangle ABC is congruent to triangle DEF. The order of the lettering is important because it tells us how the angles pair up. We see that angle B and angle E are the second letters of ABC and DEF respectively. Because the triangles are congruent, this leads to angle B = angle E.
Angle B is shown to be 20 degrees, so,
angle E = angle B
2(m-15) = 20
m-15 = 20/2
m-15 = 10
m = 10+15
m = 25
------------------
A slightly alternative way to solve:
2(m-15) = 20
2m-30 = 20
2m = 20+30
2m = 50
m = 50/2
m = 25
------------------
Checking the answer:
2(m-15) = 20
2(25-15) = 20
2(10) = 20
20 = 20
We get the same thing on both sides, so we end up with a true equation. This means the first equation is true when m = 25. The solution has been confirmed.

Answer:
Step-by-step explanation:
Find the sum
we know that
substitute
step 1
Separate the mixed number into a whole number and a fraction number
step 2
Group the whole numbers an the fraction numbers
step 3
Combine like terms
Remember that
substitute
The answer is reasonable
Because
I know that 1 3/4 < 2 and 1 5/8 < 2
so
The sum of both numbers must be less than 4
