Question 646817: 1. Translate into an equation and solve. (Use n to represent the smaller number.)
The sum of two numbers is twenty-four. Six less than five times the smaller is equal to the larger
2. Find three consecutive even integers whose sum is negative thirty-six.
3. The cost of electricity in a certain city is $0.08 for each of the first 300 kWh (kilowatt-hours) and $0.13 for each kWh over 300 kWh. Write an equation to find the number of kilowatt-hours used by a family that receives a $43.50 electric bill. (Use x to represent the kilowatt-hours over the initial 300.)
Hi,
1. x + y = 24 OR y = 24-x and
5x-6 = y,
5x-6 = 24-x,
6x = 30,
x = 30/6 = 5 & y = 19
and
2. x + (x+2) + (x+4) = -36
3x = -42 , x = -14
-14,-12,-10 are the integers.
3.
$43.50 = $24 + .13x
