Answer:
Below in bold.
Step-by-step explanation:
Let x be George's age and y be Genemy's age.
x/y = 5/7
(x + 4)/ (y + 4) = 3/4
From equation 1, y = 7x/5 = 1.4x so substituting in equation 2 :
(x + 4)/ (1.4x + 4) = 3/4
3(1.4x + 4) = 4(x + 4)
4.2x + 12 = 4x + 16
0.2x = 16 -12 = 4
x = 4/0.2 = 20 = George's age.
So y = 1.4x = 1.4 * 20 = 28 = Genemy's age.
Answer:
C. 5 by 3 by 2
Step-by-step explanation:
The surface area of a rectangular prism is given by:
If the length of the prism is
the width of the prism is
and the height of the prism is:
The surface area becomes:
Multiply within the parenthesis:
Add:
square units.
Hence the correct choice is C.
First, figure out its slope. that is (4-2)/(2-1)=2
then, write its point-slope form:
y-(-3)=2(x-2)
Answer:
y=<u>2π</u>
3
Step-by-step explanation:
3/7 is equal to 9/21 because when you simplify 9/21 you can divide both 9 and 21 with 3 so you would get 3/7
