Answer:
x = 1, y = 1
Step-by-step explanation:
3x - 4y = -1
5x + 2y = 7
If we multiply the whole second equation by 2, we get:
10x + 4y = 14
Adding this to the first equation:
10x + 4y + 3x - 4y = 14 - 1
13x = 13
x = 1
Applying this to the second equation:
5 (1) + 2y = 7
2y = 2
y = 1
Answer:

Answer:
6.30
Step-by-step explanation:
Ivanka’s ribbon = 4.5 inches long

= 7/5 x 4.5
= 31.5/5
= 6.3 = 6.30 to the nearest hundredth
The second one is incorrect
