Question
solving Algebraic Equations 2M+3=11
Answer:
<h2>
m = 4</h2>
Step-by-step explanation:
2m + 3 = 11
2m = 11 - 3
2m = 8
m = 8 : 2
m = 4
--------------------
check
2 * 4 + 3 = 11
8 + 3 = 11
11 = 11
the answer is good
40 cents, divide 20 by .05
Answer:
Step-by-step explanation:
We first need to find the measure of the other 2 angles. The angles of a quadrilateral all add up to equl 360, so:
360 - 249 - 31 = 80
The other 2 angles add up to equal 80 degrees. If these angles exist in a 3:17 ratio, then algebraically,
3x + 17x = 80 and
20x = 80 so
x = 4. That means that one angle is 3(4) = 12 and the other angle is 17(4) = 68.
249 + 31 + 12 + 68 = 360.
Angles one and four are vertical angles. Vertical angles are angles found on the opposite of the given or selected angle. Complementary angles are angles that equal 90 degrees and supplementary angles are angles that equal 180 degrees when added. Hope this helped :)
