y+0.15=x
y+x=0.69
y+y+0.15=0.69
2y=0.69-0.15
2y=0.54
y=0.54/2
y=0.27 pencils
y+0.15=x
0.27+0.15=x
0x=0.42 pen
150 pencils x0.27=40.5$
225 pens x 0.42=94.5$
Total 40.5$ + 94.50$=135 $

Answer:
e°=100°
Step-by-step explanation:
Sum of angles in a triangle= 180°
70°+30°+x°=180°
100°+x=180
Collect like terms
x°=180-100
x°=80°
e° is an exterior angle
exterior angle =180- interior angle
180°- x°
180°- 80°
=100°
e°=100°
5*5=25*3.14=78.5
3*3=9*3.14=28.26

8
<h2><u>
Step-by-step explanation:</u></h2>
<u />
Replace the x with 8.
The absolute value makes any number positive.
Since 8 is already positive, there is no change in the answer.
f(8) = 8
There are 1 right triangle, 1 rectangle and 1 trapezoid
- Solve for right triangle
1/2 x 5 x 8 = 20 cm
- Solve for rectangle
12 x 8 = 96 cm
- Solve for trapezoid
1/2 x 9 ( 5 + 10 ) = 67.5 cm
- The area of this is
20 + 96 + 67.5 = 183.5 cm
