Answer:
Step-by-step explanation:
first term (a) = 4
last term (b) = 9
Arithmetic mean (AM)
= ( a + b) / 2
= ( 4 + 9 ) / 2
= 13/2
= 6.5
Geometric mean (GM)
= √a *b
=√4 * 9
=√36
= 6

Answer:
215; 8; 367
Step-by-step explanation:
231=7x+c
319=18x+c
c=The amount from bake sale (since it doesn't changes throughout the car wash)
x=$ earned per car
319=18x+c
-(231=7x+c)
Use elimination and subtract the values to get rid of a variable.
(319-231, 18x-7x, c-c)
88=11x
x=88/11
x=8
∴ The soccer team earns $8 per car.
231=7*8+c
231=56+c
c=231-56
c=175
∴ The soccer team made $175 from the bake sale.
The ans. is per blank from top ro bottom
1. c+5x=175+5*8
175+40 = 215
2. 255=c+?x
255=175+?*8
255-175=?*8
80=?*8
?=80/8
The soccer team washed 8 cars n earned $255
3. c+24x=175+24*8
175+192= 367
The soccer team earned $367 after 24 cars.
