Divide the y-value by the x-value.
(1/2) / (2/5) = 1/2 x 5/2 = 5/4
Answer:
the man is 52 years old
Step-by-step explanation:
man: 35+x
son:x
y=884/x
x(35+x)=884
35x+x^2=884
35x+x^2-884=884-884 . 884/-17+52=35
x^2+35x-884=0
(x-17)(x+52)=0
x=17 . x=-52 (age can't be negative)
man:35+17=52

Answer:
A. (3, 3)
Step-by-step explanation:
The coefficients of y are opposites, so adding the two equations will eliminate y.
(x +2y) +(3x -2y) = (9) +(3)
4x = 12 . . . simplify
x = 3 . . . . . divide by 4
Using the first equation, we can find y:
3 +2y = 9 . . . . . .substitute for x
2y = 6 . . . . . . . . subtract 3
y = 3 . . . . . . . . . . divide by 2
The solution is (x, y) = (3, 3).

<em>Additional comment</em>
For this problem, it is easy to just try the answers. You don't have to go far to show the first answer (A) satisfies both equations.
3 + 2(3) = 9; 3(3) -2(3) = 3
Is a supposed to be the answer? Is there any other options to choose from the no given list?
Answer:
D
Step-by-step explanation:
To write an expression and equation, define the variables.
Taylor purchased three types of items:
x = number of bags of candy
y = number of picture frames
z = number of stickers.
We know she bought 9 items.
So x+y+z = 9.
