Solve -3(x+5) = -9 solve

Bumek [7]

-3(x + 5) = -9
-3x + -15 = -9
-3x - 15 = -9
-3x - 15 + 15 = -9 + 15 (we added 15 to both sides of the equation because now, the 15 on the left side cancels out).
-3x = 6
-3x/-3 = 6/-3
X = -2
So, in conclusion, X is equal to -2.

Solve each system by elimination 10x-8y=4 -5x+3y=-9

mariarad [96]

$10x-8y =4~~~....(i)\\\\-5x+3y=-9~~~...(ii)\\\\\text{Multiply equation (ii) by} -2\\\\10x-6y = 18~~~...(iii)\\\\(iii)-(i):\\\\10x-6y - 10x +8y = 18 -4\\\\\implies 2y = 14\\\\\implies y= \dfrac{14}2 = 7\\\\\text{Substitute y = 7 in equation (i):}\\\\10x-8(7) =4\\\\\implies 10x - 56 =4\\\\\implies 10x = 4+56\\\\\implies 10x = 60\\\\\implies x = \dfrac{60}{10} = 6\\\\\\\text{Hence (x,y) = (6, 7)}$

12 out of 30 people chose their favourite colour as blue calculate the angle you would use for blue on a pie chart

sergey [27]

First, I'll calculate the percentage:

$\frac{12}{30} *100%= \frac{12*100}{30} = \frac{120}{3} =40$

so it was 40 % of people that chose blue

And now we can calculate the angle;

the full chart would have 360 Degrees, and the "blue" portion of the chart would have 40 % od 360 or $\frac{40*360}{100} =4*36=120+24=144$

so the angle would be 144 degrees!
