Answer:
Step-by-step explanation:
Let the first integer be x, then the next is x+1.
x(x + 1) = 3(x + 1) + 4
x^2 + x = 3x+ 3 + 4
x^2 + x - 3x - 7 = 0
x^2 - 2x - 7 = 0
Solving this does not give an integer so maybe there's something wrong with the question??
Answer:
D) 200
Step-by-step explanation:
To find what x equals you have to use the expression:
is over of equals percent over 100
In this problem you are given the percent, 65%, and the is, 130.
So we are trying to find the of so you would substitute of with x.
So 130/x = 65/100
Now you would do Cross Product Property to find x.
So 130*100 = 13000
65*x = 65x
65x = 13000
65/65 = 1
13000/65 = 200
x = 200
So 65% of 200 is 130
