Answer:
(3, - 3 )
Step-by-step explanation:
Given the 2 equations
3x - 5y = 24 → (1)
- 3x - 6y = 9 → (2)
Adding the 2 equations term by term will eliminate the x- term, that is
- 11y = 33 ( divide both sides by - 11 )
y = - 3
Substitute y = - 3 into either of the 2 equations and solve for x
Substituting into (1)
3x - 5(- 3) = 24
3x + 15 = 24 ( subtract 15 from both sides )
3x = 9 ( divide both sides by 3 )
x = 3
solution is (3, - 3 )
Answer:
$46.99
Step-by-step explanation:
Since both dresses that cost the same add up to a total price of $93.98, all you have to do is divide the total price by 2.
93.98/2=46.99
8 multiplies to 16 but what do you mean about adds to one

Answer:
The first two.
Step-by-step explanation:
See that L is 600mm MORE than W.
From there, you can note that L = W+600
or rearrange the formula and get W= L-600
Then, see that the perimeter of a flag is 2L + 2W
(Because there are two four sides to a rectangle, 2 width, 2 length)
It must total to be 5 meters, or 5000mm
Thus,
2L + 2W = 5000
