His new apartment will cost him "10% more" than what he is paying currently.
100% = current rent
10% = the extra amount he will pay for his new apartment
100% + 10% = new rent
100% + 10% = 110%
Now convert the percent into a decimal by moving the % sign two places to the left and make the % sign into a decimal point.
110% = 1.10
500 * 1.10 = 550
So, he will pay a rent of $550 for his new apartment.
Answer: -4x + 2y
Step-by-step explanation:
6x - 3y + 5y - 10 x
Group like terms:
= 6x - 10x - 3y + 5y
Add similar elements :
6x - 10 x = - 4x
- 3y + 5y = +2y
Therefore:
-4x + 2y
Hope that helps!
Answer:
3
Step-by-step explanation:
Consider 3 girls are doing an embroidery work. Let g be the number of hours needed for the first girl to complete the work and h be the number of hours needed for the second girl to complete the work.
If the number of hours needed for the third girl is the sum of the hours needed to complete the work by the first girl and 3 hours less than the hours needed to complete the work by the second girl, write the expression for the total hours needed for the third girl to complete the work.
No. of hours needed for first girl = g
No. of hours needed for second girl = h
So, number of hours needed for third girl = g + (h - 3).
