I believe that the answer to this question is 30.345 cm
Answer:
x=-15, y=25. (-15, 25).
Step-by-step explanation:
2x+3y=45
x+y=10
--------------
x=10-y
2(10-y)+3y=45
20-2y+3y=45
20+y=45
y=45-20
y=25
x+25=10
x=10-25
x=-15
Answer:
Step-by-step explanation:
Here are some steps to help you
Step 1
4x-3≥13 We are going to be simplifying
Step 2
4x-3≥13 Add 3 to the sides
4x≥16
Step 3
4x≥16 Divide them sides by 4
x≥4
So therefore your answer is x≥4
Hope this helps
Answer: -5
Step-by-step explanation: 2 + -11 = -9 and subtract -4 from it since it’s the sum of 2 + -6. -9 - -4 is -9 + 4 so -5
Answer:
All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)... And there are nine angles... So, the measure of the angle of a regular nonagon is 140 degrees.
