Answer:
5y + 3x + 9
Step-by-step explanation:
Whenever something is multiplied by the same variable, you can combine the coefficients. In this case, first you'd move the values with the same variable next to each other, for simplicity:
7y-2y+3x+3+6
Then, combine like terms.
5y+3x+3+6
5y+3x+9
Person A takes 2.3 days to paint the house working alone
Person B takes 13.8 days to paint the house working alone
<em><u>Solution:</u></em>
Let "x" be the number of days it takes person A to paint the house
Person A can paint the neighbor's house 6 times as fast as Person B
Therefore.
Number of days it takes person B to paint the house = 6x
Their rates of painting are added to get the rate working together
Thus person A takes 2.3 days to paint the house working alone
Person B = 2x = 6(2.3) = 13.8
Thus person B takes 13.8 days to paint the house working alone

Step-by-step explanation:
This problem involves using ratios to compare side lengths in similar triangles.
136/34=x/1.5
136/34*1.5=x/1.5*1.5
136/34*1.5=x
x=6

Answer:
$930
Step-by-step explanation:
The amount payable at maturity of the loan is simply the sum of the loan amount and the fee charged on the loan.
The loan amount is 890 while the fee charged on the loan is 40. The amount repayable at maturity is thus;
890 + 40 = 930.
Therefore, he has to pay $930 by the time the loan reaches maturity.
