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.
Answer:
I think it is 160 x2 so you would probably divide 160 by x2 which would 144
Step-by-step explanation:
(2x5+3)8=104
2x5=10
10+3=13
13x8=104
Hope that makes sense! :)
Let's have a look:
2(4)= 8 (this would not work)
5(4)= 20 (this wouldn't work)
7(4)= 28 This does, let's check the others.
7(6)= 42 This does not work.
"D" would be the correct answer.
I hope this helps!
