Answer:
9) p = 48
10) a = 3.6
Step-by-step explanation:
9) p/8 + 3 = 9
p/8 = 6
p = 48
10) 12a/4 + 18/3 = 20.4
4a + 6 = 20.4
4a = 14.4
a = 3.6
C because first you do ( 4+2 ) = 6 and 10 - 6 = 4
Answer:
An equilateral triangle has equal sides and all of its angles are equal as well. We also know that a triangle's angles add up to 180°. Therefore, if we were to divide 180° evenly between the three equal angles, we would discover that each angle measures 60°. Your answer is C.

Answer:
x = 12 and y = 23
So what we are saying is that the coordinates of Tina’s house down the street is (12,23)
Step-by-step explanation:
What this question is actually telling us is that the gas station divides the segment from George’s home to Tina’s house in the ratio 3 to 7; we now want to find the coordinates of Tina’s house which is the end of the line segment.
Mathematically, to get this division, we would have employed the use of the internal division formula;
Coordinates of gas station = (mx2 + nx1)/(m + n) , (my2 + ny1)/(m + n)
m = 3 , n = 1
(x1,y1) = (2,3)
(x2,y2) = (x,y)
So therefore;
(5,9) = 3(x) + 7(2)/3+7) , 3(y) + 7(3)/(3+ 7)
(5,9) = (3x + 14)/10, (3y + 21)/10
Hence;
(3x + 14)/10 = 5
3x + 14 = 10(5)
3x + 14 = 50
3x = 50-14
3x = 36
x = 36/3
x = 12
Also;
(3y + 21)/10 = 9
3y + 21 = 9(10)
3y + 21 = 90
3y = 90-21
3y = 69
y = 69/3
y = 23
