Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
3x +2y = 5 → (1)
x - 2y = - 1 → (2)
Adding the 2 equations term by term will eliminate the term in y, that is
(3x + x) + (2y - 2y) = (5 - 1)
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 in either of the 2 equations and solve for y
Substituting in (1)
3(1) + 2y = 5
3 + 2y = 5 ( subtract 3 from both sides )
2y = 2 ( divide both sides by 2 )
y = 1
Solution is (1, 1 )
Answer:
D
Step-by-step explanation:
Take the total amount needed and subtract the amount they have
190.44 -34.20
156.24
Divide by the number of weeks they are saving
156.24/8
19.53
They need to save more than this amount because they need to save more than 190.44.
There is an open circle at 19.53 and a line going to the right
