Step-by-step explanation:
a & b are the correct answers
Step 1:
Let us first find the decrease in amount.
Decrease in amount = 150 -120 = $30
Step 2:
Now let us find the ratio of decrease in price to original price.
So the ratio is 1/5 or in decimal its 0.2.
Step 3:
To find percentage decrease we change this decimal number 0.2 two places to the right side, so it becomes 20 %
The price decreased by 20%
Answer:
18
Step-by-step explanation:
A two-digit number (xy) will have the value 10x+y. The sum of its digits is x+y.
You want ...
10x +y = 2(x +y)
1 ≤ x ≤ 9
0 ≤ y ≤ 9
The equation can be simplified to ...
8x = y
The only single-digit values for x and y that satisfy the requirements are ...
x = 1, y = 8
The two-digit number of interest is 18.
_____
Check
Its sum of digits is 1+8 = 9. 2×9 = 18.
_____
Comment on the relationship in the problem
Many of us learned our multiplication tables for 9s by remembering that the sum of digits of 9n was 9, and that the leading digit of the product was n-1.
Answer:
the statement is x=y/8 the number is 18

Answer:
Width = 57cm
Step-by-step explanation:
The area of a rectangle can be found by using the formula:
Area = Length * Width
Since we know that the area is 4275cm² and the length of the painting is 75cm, we can plug these into the above equation to solve for the width.
Area = Length * Width
4275cm² = 75cm * Width
To find the width, we can simply divide both sides by 75 so that the width measurement is isolated:
Width = 57cm
To verify this, we can multiply the length and width to see if the area equals 4275cm²:
75cm * 57cm = 4275cm²
