Answer:
(3, 2)
Step-by-step explanation:
First, we have to eliminate a variable:
3(5x+2y = 19
)
2(4x-3y = 6)
------------------
15x+6y = 57
8x-6y = 12
Now we add the system of equations together:
15x+8x+6y-6y = 57+12
23x = 69
/23 /23
x = 3
Now we can plug this value back into one of the equations to get y:
5(3)+2y = 19
15+2y = 19
-15 -15
2y = 4
/2 /2
y = 2
Therefore, the solution to these system of equations is (3, 2)
You have to times 11 by 8
Answer:
French and Spanish = 8 , French = 23, Spanish = 15
Step-by-step explanation:
60 - 14 = 46
31+23 = 54
54-46 = 8
31- 8 = 23
23 - 8 = 15
15 + 23+8+14= 60
Answer:
No
Step-by-step explanation:
Find the rate and compare.
4 hrs = £24
8 hrs = £50
24 ÷ 4 = £6 per hour
50 ÷ 8 = £6.25 per hour
As you can see, the rate is not the same, so Vince's pay is not proportional at all.
