Answer:
D or A
Step-by-step explanation:
(D) One circle : four triangles
Example:
One triangle is 1/4 of a circle
(A) One circle : four triangles
Example:
If there is two circles, the triangles will double like it shows [evidences]
2x + 3y = 45
x + y = 10......y = 10 - x
2x + 3(10 - x) = 45
2x + 30 - 3x = 45
-x + 30 = 45
-x = 45 - 30
-x = 15
x = -15 <====
and y = 25
Answer:
Step-by-step explanation:
y= -5x/2+1
Answer:
<h2><u><em>
x = 5</em></u></h2>
Step-by-step explanation:
What is the X
3x +15 and 2x + 20
assuming that the question is an equation
3x + 15 = 2x + 20
3x - 2x = 20 - 15
x = 5
-----------------
check
3 * 5 + 15 = 2 * 5 + 20
30 = 30
the answer is good
