4x+3=3(x+3)
4x+3=3x+9
4x-3x=9-3
x=6
So The Father is 24 and the Son is 6
Responder:
Pantalón = 50 €
Zapatos = 76 €
Explicación paso a paso:
Total pagado por pantalón y zapatos = 126
Sea el precio del pantalón = p; zapatos = s
p + s = 126
1,14 p = 0,75 s
p = 0,75 s / 1,14
0,75 s / 1,14 + s = 126
(0,75 s + 1,14 s) / 1,14 = 126
0,75 s + 1,14 s = 143,64
1,89 s = 143,64
s = 143,64 / 1,89
s = 76
p + s = 126
P = 126 - s
P = 126 - 76
p = 50
Answer:
You get 12$ per B and 15$ per A. Thus, the answer is A) $282
Step-by-step explanation:
4A+4B=108
Divide by 4
A+B=27
Subtract B
A = 27 - B
3A+5B=105
Substitution
3(27-B)+5B = 105
Distribute
81-3B+5B=105
Combine like terms
81+2B=105
Subtract 81
2B=24
Divide by 2
B = 12
A = 15
14(15)+6(12)=x
210+72=x
282=x

The statement in option D is TRUE.
From the graph, you can see that one eraser cost 50 cent and all the eraser cost the same. Following the graph, you will observe that, when the total cost of the eraser is $3.5 on the vertical axis, the corresponding point on the horizontal axis is 7.
That particular plot on the graph is telling you that when seven erasers are bought, the total cost is $3.5.
