The student made the mistake in Step 2.
It should be m∠o + m∠p = 180 (Supplementary angles)
If this is corrected, then, since m∠m + m∠n + m∠o = 180 from Step 1,
we have,
m∠m + m∠n + m∠o = m∠o + m∠p which is Step 3.
Cancelling m∠o both sides, we get,
m∠m + m∠n = m∠p which is Step 4.
Answer:
14
Step-by-step explanation:
you clean 2 a hour so 7*2=14
Answer:
38
Step-by-step explanation:
substitute the value of the variable into an equation, then simplify
36÷6 is 6 to show your work for it maybe draw it out and better show the equation like when you solve a bigger problem.
20 and 22
You would create an equation that would simulate this situation and solve for x to find the first even integer. Then add 2 to x to find the second even integer.
