Answer:
2%
Step-by-step explanation:
Let x be the first number
It increases by 70 %
The new number is
m = x+ .70x
= 1.7x
Let y be the second number
It decreases by 40 %
The new number is
n =y - .40 y
= .6y
The product of the original numbers is xy
The product of the new number is
mn = (1.7x * .6y) = 1.02xy
The new number is larger than the old number so it is an increase.
Percent increase is new - original divided by original times 100%
Percent increase = (1.02 xy - xy)
----------------- * 100%
xy
= .02 xy
------- * 100 %
xy
= .02 * 100 %
= 2%

Answer:
Step-by-step explanation:
At first sight this equation has 3 terms. Multiply all 3 of them by 10 to remove the fractions:
4b + 13 = 4(b - 5)
Carrying out the multiplication, we get:
4b + 13 = 4b - 20
This can never be true (13 is never equal to -20), so this equation has NO SOLUTION.
