Step-by-step explanation:
450% × 594 =
(450 ÷ 100) × 594 =
(450 × 594) ÷ 100 =
267,300 ÷ 100 =
Answer:
x= - 50/9
Step-by-step explanation:
multipy both equations by 12
9x+60=10
then move the constant to the right hand side and change it's sign
9x= 10 - 60
calculate difference
9x = -50
divide both sides by 9
x= - 50/9
Answer:
A
Step-by-step explanation:
So firstly, what two terms have a product of 8x^2 and a sum of 9x? That would be x and 8x. Replace 9x with x + 8x: 
Next, factor x^2 + x and 8x + 8 separately. Make sure that they have the same quantity on the inside: 
Now you can rewrite the equation as 
Now using zero product property, solve for x:

<u>In short, the solutions are {-1,-8}, or C.</u>
