Answer:y=6.61,x=-6.46
Step-by-step explanation:
3x+7y=-26(×5)
-
5x+3y=-14(×3)
=15x+35y=-130
-
15x+9y=-42
subtracting the 2 equations =15x-15x+35y-9y=-130-(-42)
=26y=172
y=172÷26
y=6.61
substitute y in the first equation=3x+6.61=-26
3x=-26+6.61=-19.39
x=-19.39÷3
x=-6.46
Answer:
el 5
Step-by-step explanation:
La mediana es el número intermedio de un grupo de números; es decir, la mitad de los números
Primero se acomodan de menor a mayor y luego ubicaras el número que queda en medio
(51 - 22)/51 × 100% = 29/51 × 100%
= 56.86%
$8,000 + $1,500 = 9,500
So 9,500 x .6 = 5,700 dollars donated by trustee.
$9,500 + $5,700 = $15,200 dollars tota
Answer:
C(C^3 + 8C^2 -3C -7)
Step-by-step explanation:
(-3C^4-5C^2-7C)+(4C^4+8C^3+2C^2)
(-3C^4 +4C^4)+8C^3 + ( -5C^2 +2C^2) -7C [Combine like terms]
C^4 + 8C^3 -3C^2 -7C [Simplify]
C(C^3 + 8C^2 -3C -7) [Isolate 1C from the rest]
