Answer:
José has 49 used stamps
Step-by-step explanation:
7 used stamps for every 4 new stamps
To solve this type of problem, we can use a ratio
7 : 4 ratio
He has 28 new stamps
7 : 4 = x : 28
Ratios can be written as fractions
Cross multiply
4x = 7(28) = 196
Divide by 4 on both sides
x = 49

Answer:
The solution is the point (6,-1)
Step-by-step explanation:
<u><em>The correct question is</em></u>
Solve the system of equations and choose the correct ordered pair. 2x+6y=6 and 3x-2y=20
we have
----> equation A
---> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The intersection point both lines is (6,-1)
see the attached figure
therefore
The solution is the point (6,-1)
