The ratio is 1:7. This means there are 8 total parts. Start by dividing 40 by 8. This equals 5. Each part equals five, so the white marbles are 5. However, question asks for the number of RED. 7 of the 8 parts are red. 7*5 is 35 so there are 35 red marbles.

Tashia paid two months rent and a $500 security deposit when she signed her lease. In total, she paid $2,400.
fiasKO [112]

The equation that represents the scenario is  2x + 500 = 2400

The cost of one month rent is $950

She paid two months rent and a $500 security deposit when she signed for a lease. In total she paid $2400.

let

the cost of a month rent = x

Therefore,

<h3>Total cost Equation</h3>
  • 2x + 500 = 2400

The cost of the one month rent can be calculated as follows:

  • 2x + 500 = 2400
  • 2x = 2400 - 500
  • 2x = 1900
  • x = 1900 / 2
  • x = $950

Therefore, the equation that represent the scenario and cost of one month rent are as follows;

  • 2x + 500 = 2400
  • cost of one month rent = $950

write an equation in standard form with integer coefficients for the line with slope 6/11 going through the point (-1,-6)
yKpoI14uk [10]
If the slope is 6/11 then, in y=mx+b form, m will be 6/11.  When you multiply 6/11 and -1 you get -6/11.  To get the y (-6), you have to add -60/11.  So in, y=mx+b form the equation is y=6/11x+(-60/11).  To make it standard form, you add negative 6/11x to both sides and then multiply by 11 to get rid of the fractions. So therefore the equation would be:

-6x + 11y = - 60
