Answer:
63/90 = 7/10
Step-by-step explanation:
63 = 3²×7
90 = 2×3²×5
The factor of 3² is common to both numbers, so the fraction reduces to ...
... 63/90 = (3²×7)/(3²×10) = 7/10
Notice that we have a difference of squares in the numerator of our expression. In the denominator we have a quadratic expression of the form
. So we can factor both numerator and denominator and cancel common terms:
We can conclude that the correct answer is the fourth one:
Answer:
x= -3/11
Step-by-step explanation:
Use cross multiplication:
5(x+1)= -1(6x-2)
Simplify:
5x+5= -6x+2
Subtract 5 from both sides:
5x= -6x-3
Add 6x to both sides:
11x= -3
Divide both sides by 11:
x= -3/11
