Last month, the soccer team held a bake sale to raise money for new uniforms. They did not raise enough money, so they organized
VLD [36.1K]

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.

Histograms answer 6th grade math
mrs_skeptik [129]
6. 6th grade- go to the two columns above $600, which is about 8 students in the first column and 5 students in the 2nd. 8 + 5 = 13, so 13 students in 6th grade earned $600 or more. 
7th grade- again, go to the columns above $600, which is about 7 students in the first column and about 3 in the 2nd column. 7 + 3 = 10, so 10 students in 7th grade earned $600 or more.

Do the same thing for #7, just follow the rows exactly as #6.
