80 degrees
Step-by-step explanation:
Answer:
Part A: 30%
Part B: 45000%
Step-by-step explanation:
To get your answer, you have to divide whatever number the down payment is by the number the family is supposed to pay for the studio apartment.
Part A: You need to divide $54.00 by $180.00, when you do that, you get the answer 0.3. You convert it to percentage by doing 0.3 multiplied by 100 which give you 30. Put a percent behind it and you have 30% as your final answer.
Part B: You need to divide 81,000 by 180 which gives you 450. Then you then have to do 450 multiplied by 100 which gives you 45,000. You then add the percentage behind and you have 45000% as your final answer.
Answer:
2x + y = 17
-6x = 3y - 51
Step-by-step explanation:
You get an infinite number of solutions when two equations are really just the same. This means you can convert one into the other simply by multiplying one to get the other.
In the above answer, if you multiply the above by -3 you get:
-6x -3y = -51
which is of course -6x = 3y - 51
So that is an example of a pair that has infinite solutions.
To find all of them, you'd carefully have to compare each 2 and see if there is a multiplier to convert one into the other. You can do that!
Answer:
The error she made was that she was adding x and 2.75. She should subtract 2.75 from x.
Another mistake that she made was that she sold each for $7 assuming that she would make a profit of 78, but she should see each necklace for $12.5 so that she could make a profit of $78.
Step-by-step explanation:
The error she made was that she was adding x and 2.75.
She should write the equation as 8 (x - 2.75) = 78; as she spends $2.75 to make a necklace.
By using the correct equation: 8 (x - 2.75) = 78
=> 8x - 22 = 78
=> 8x = 78 + 22
=> 8x = 100
=> x = 100/8
=> x = 12.5
Another mistake that she made was that she sold each for $7 assuming that she would make a profit of 78, but she should see each necklace for $12.5 so that she could make a profit of $78.
Hope this helps you.
