Answer:
d=-4
Step-by-step explanation:
20 = –d + 16
Subtract 16 from each side
20-16 = –d + 16-16
4 = -d
Multiply each side by -1
-1 *4 = -1 * -d
-4 =d
Answer:
She deposited $7500. So it is the principal.
At the end of years, she had total of $8700.
So the total amount is $8700 and the time period is 2 years.
Interest = Total amount - principal = $8700 - $7500 = $1200
We need the rate of interest.
we know that Interest = PTR/100
⇒1200 = 7500*2*R/100
⇒R = 1200*100/7500*2
⇒R = 120000/15000 = 8%
Rate of interest is 8%

Hello!
5 = 5/1 as a fraction
2/5 × 5/1 = 2
ANSWER:
The product of 2/5 and 5 is greater than 2/5, and less than 5.
Another way you could find out if it's greater or less is by converting the fraction to a decimal and then multiplying it.
You must divide the numerator by the denominator to convert a fraction to a decimal.
2 ÷ 5 = 0.4
0.4 × 5 = 2
Let the length and breadth of the rectangle be x and y.
Area of rectangle is A = xy
Therefore, the new length will be = x-5
Therefore, the new breadth will be = y + 3
So new area will be xy-9
Now the new relation will be (x+3)(y+2)=xy+67
.
Cross – multiplication method–
Therefore, the length is 17 and breadth is 9.
