Sería 37975 porque le tienes que restar el procentaje que se le ha añadido para saber cómo era antes
You have to use the substitution method by substituting one Y value with the other
T: 8x+19
7x-2(4-2x)+6(5-x)-x+2-(6x+5) = 7x-8+2x+30+6x-x+2-6x-5 = 8x+19
Y: 56-8x
9-(-2-3x)+4(-x+6)-x+12-3(2x-3) = 9+2+3x-4x+24-x+12-6x+9 = 56-8x
Answer:
We are solving for the area so; A=134.16
Step-by-step explanation:
$39.40 all together. You would multiply the cost of 2.90 by the amount needed which is 6 and get you an answer of 17.4. Then you would multiply the cost of 4.40 by the amount needed which is 5 and get you the answer of 22. You would then add the sums 17.4 and 22 and get you your answer of $39.40
