Let the first integer be x; then the second is x+1.
The product of x and x+1 is x(x+1), and this product must equal 1295.
Thus, x^2 + x = 1295, or x^2 + x - 1295 = 0
Solve for x by completing the square:
x^2 + x + (1/2)^2 - (1/2)^2 - 1295 = 0
(x-1/2)^2 - 1/4 - 1295 = 0, or (x-1/2)^2 -5181/4 = 0,
Thus, x-1/2 = sqrt(5181/4), and so
x = 1/2+sqrt(5181/4) = 25.45
This could NOT be correct, since x and x+1 are CONSECUTIVE INTEGERS.

Answer:
$15 per hour
Step-by-step explanation:
what’s the ratio of $30 in 2 hours.
= $30 / 2 hours
= $15 per hour
12 because the smaller the whole the bigger the fraction
Answer:
See below.
Step-by-step explanation:
Here is an example:-
Solve by elimination:
2x - 3y = 0
3x + 2y = 13
To eliminate the y terms Multiply the first equation by 2 and the second by 3. This gives:
4x - 6y = 0
9x + 6y = 39 Adding the 2 equations:
13x + 0 = 39
13x = 39
x = 39/13 = 3
Finally we find y by plugging x = 3 into the first equation:
2(3) - 3y = 0
3y = 2(3) = 6
y = 2.
Y = 1.5m + 18
This is because of the rate and yearly membership.
