Answer:
y = 1/2x - 3/2
Step-by-step explanation:
y = 1/2x + b
1 = 1/2(5) + b
1 = 5/2 + b
-3/2 = b
First, set up an equation that models this statement.
N is your variable because it’s the unknown Number.
8n-13=43
Then, add 13 on both sides so you have the variable and it’s coefficient alone.
8n-13=43
+13.+13
________
8n=56
Then, divide the variable and the coefficient by the coefficient.
8n=56
—. —
8. 8
Now you have your variable all by itself, and you have the persons number.
n=7
Your number is 7.
ANSWER
a=53°
b=106°
c=74°
d=37°
EXPLANATION
A semicircle creates a right angle on the circumference.
d+53°=90°
d=90°-53°
d=37°
Angle subtended at the center by an arc is twice the angle subtended at the circumference by the same arc.
c=2d
c=2(37)
c=74°
Adjacent angles on a straight line add up to 180°
c+b=180°
b=180°-c
b=180°-74°
b=106°
The sum of interior angles in an isosceles triangle is 180°
a+a+c=180°
2a+74=180
2a=180-74
2a=106
a=53°
Answer:
12
Step-by-step explanation:
If there is 3 tickets and it cost 36 dollars you will divide 36 by 3 and get 12
