The sum of 2 numbers is 25. Their difference is 7. Find the numbers. Let x=1st number and y=2nd number
Alex Ar [27]

Answer:

x= 16 and y = 9

Step-by-step explanation:

1 st equation ; x+y = 25

2 nd equation ; x- y = 7

from 1 st equation

x = 25 - y

now putting value of x in 2 nd equation

x- y = 7

25 - y-y = 7

25 -2y =7

25-7 = 2y

18 = 2y

18/2 = y

y = 9

again

putting value of y in 1 st equation

x = 25-y

x = 25-9

x= 16

Shawn drew a rectangle that had a width of 4.2 inches and a length of 8.1 inches. Find the perimeter of Shawn's rectangle
MArishka [77]

Answer: 24.6 inches


Step-by-step explanation: Since it's a rectangle, and not a rectangular prism, that means it's 2D. Length is the long sides on the top and bottom, and width is the shorter sides on it's left and right. So since there's two of each, just do 8.1 + 8.1 + 4.2 + 4.2 and you have your answer!
