The sum of b and f is b+f
Three times this sum is 3(b+f)
20 nickels = 1 dollar
So, do 20 x 17.

The answer is 340 nickels!
Answer:
2.
i) (c)
ii) (d)
iii) (b)
iv) (a)
3.
ii) 80°
Step-by-step explanation:
2.
i) 2x+x+3x=180°
x=30°
ii) x+110=180
x=70
iii) x+2x+30°=180
x=50°
iv) 2x+15°+45°+x=180
3x+60°=180
x=40°
3.
ii) 2x+5+25=180°
2x+30°=180°
x=75°
the measure: x+5°= 75°+5°=80°
point-slope equation - y+3= -3/5( x+5)
slope-intercept form- y= -3/5x +b
If the volume of a cube is 27 it means that one edge is equal to the cube root of 27
3*3*3=27
Edge=3
