25:1 describes price to uniforms because each one costs $25
Answer:
(8.5, - 2 )
Step-by-step explanation:
Given the 2 equations
6x + 4y = 43 → (1)
2x - 3y = 23 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the term in x
- 6x + 9y = - 69 → (3)
Add (1) and (3) term by term to eliminate x, that is
13y = - 26 ( divide both sides by 13 )
y = - 2
Substitute y = - 2 in either of the 2 equations and solve for x
Substituting into (1)
6x + 4(- 2) = 43
6x - 8 = 43 ( add 8 to both sides )
6x = 51 ( divide both sides by 6 )
x = 8.5
Solution is (8.5, - 2 )
X = largest, y = smallest
x + y = 38
x = 3y - 2
3y - 2 + y = 38
4y - 2 = 38
4y = 38 + 2
4y = 40
y = 40/4
y = 10
x = 3y - 2
x = 3(10) - 2
x = 30 - 2
x = 28
ur numbers are 10 and 28
