The answer to this question is 81
Answer:
$58,560
Step-by-step explanation:
First step: set up your proportion equation. Keeping the percents on the bottom, I set it up as $48,000/100% = $x/122%. I'm writing it as 122% rather than 22% so we don't have to add the increase in price to the original price later. You can see that, in order to get from 100 to 48,000, you need to multiply by 480, so you can do this to 122 to get x. Your teacher might, instead, want you to cross multiply. Do what's expected of you. Either way, your result should be $58,560. Check that it makes sense by checking that it's an increase and that it looks reasonable for the amount of the increase and you're done.
Answer:
x = 5.5
Step-by-step explanation:
Since the shape is a parallelogram, the opposite angles are congruent. Angle A is opposite Angle Y so we can set their values equal to each other to solve for x:
3x + 10 = 2x + 15.5
Bring the variables to one side and the constants to the other:
<u>x = 5.5</u>
11 divided by 2 is 5.5
5.5 divided by 10 is 0.55
Answer:
Step-by-step explanation:
Question 1:
x² = -8x - 7
x² + 8x = -7
(x + 4)² = 9
So the answer is (x + 4)² = 9
Question 2:
(x + 4)² = 9
So x = -4 ± 3
