Find three consecutive odd integers whose sum is-213.

Degger [83]

X + x + 2 + x + 4 = -213
3x + 6 = -213
3x = -219
x = -73
-73 + 2 = -71
-73 + 4 = -69
Solution: -73, -71, -69

PLEASE HELP! (WILL GIVE BRAINILEST ANSWER)

RoseWind [281]

A) we know, all the angles in a triangle is equal to 180
So, 35 + 52 + 3(x + 2) = 180
87 + 3x + 6 = 180
3x = 180 - 93
x = 87/3
x = 29

b) Now, Angle C = 3(x + 2)
C = 3(29 + 2)
C = 3(31)
C = 93

Hope this helps!

Find the x-intercept of the line whose equation is 8x + 2y =4

Alex787 [66]

Answer:

<h2>x - intercept= 1/2</h2>

Step-by-step explanation:

$8x + 2y =4\\Substitute ,y for ;0\\8x+2(0)=4\\8x+0=4\\8x=4\\\frac{8x}{8} =\frac{4}{8} x = 1/2\\(\frac{1}{2} , 0) -x-intercept$

METHOD 2

$(-\frac{c}{a} , 0)\\a = 8\\b = 2\\c = -4\\\frac{-(-4)}{8} \\x-intercept = \frac{4}{8} \\\\x-intercept = \frac{1}{2}\\(1/2 , 0)$
