Primeiro multiplica o -2 com tudo que tem dentro do parenteses (chuveirinho) -114 = -5x -2(4x+18)
-2 . 4x = -8x + -2 . 18 = -36 = -8x-36
Agora soma os números com incógnitas (no caso x)
-114 = - 5x - 8x -36
Joga a incógnita do outro, tornando positiva
-114 = -13x - 36
13x -114 = -36
e o 114 do outro lado, ficando positiva também
13x -114 = -36
13x = - 36 + 114
13x = 78
x = 78 /13
x= 6

Answer:
It would be selected 130 times.
Step-by-step explanation:
peach chew was selected 13 times out of 60, so 13/60 will be peach
multiply the amount by 600, 13/60 * 600 = 130
A line that's perpendicular would have a slope that the negative reciprocal of the line in the question
1. use the points to find the slope
(y1-y2)/(x1-x2)
=(-3-7)/(-7+5) (it's +5 because --5=+5)
=-10/-2
-5
slope of the line is -5
2. The negative reciprocal is basically flipping over a fraction (3/4 would become 4/3) and then multiplying it by -1 (4/3 would become -4/3)
Because -5 is really -5/1 you would flip it to -1/5 then multiple by -1 to equal 1/5.
3. Now we just need any line that has a slope of 1/5
y=mx+b where m=1/5 and b is whatever number you want
y=1/5x+8
y=1/5x-193748
y=1/5x-103595
All these are right answers just pick your favourite number for b

Hello from MrBillDoesMath!
Answer:
#39 6.1 (approx)
$41 14.6 (approx)
Discussion:
# 39
From plane trigonometry
cos(69) = x/17 or
x = 17 * cos(69) = 6.1 (approx)
#41
sin(59) = x/17 or
x = 17 * sin(59) = 14.6 (approx)
