You really have 2 separate equations to solve here:
1) 5(x-1) = - 20 => 5x - 5 = -20 => 5x = -15 => x = -3
2) 3y = -15 => y = -5
Answer:
<u>The width of the rectangle is 6 cm and its length is 9 cm</u>
Step-by-step explanation:
Length of the rectangle = 3 cm greater than its width
Perimeter of the rectangle = 30 cm
Find the dimensions of the rectangle.
x = Width of the rectangle
x + 3 = Length of the rectangle
Now, let's solve for x, using the perimeter formula this way:
2 * width + 2 * length = Perimeter of the rectangle
Replacing with the values and variables we have:
2 * x + 2 * (x + 3) = 30
2x + 2x + 6 = 30
4x = 30 - 6
4x = 24
x = 6 ⇒ x + 3 = 9
<u>The width of the rectangle is 6 cm and its length is 9 cm</u>
Answer: c is the correct answer
Step-by-step explanation:
Answer:
On first visit, weight =550 g
Weight gained on second visit= 350 g
Weight gained on third visit= 300 g
Present weight=550+350+300= 1200
Weight gained=1200-550=650
Percentage of weight increased
-------->650/550 × 100 = 118.18\%
So the kitten gained 118% weigh
