Answer:
it's ≤40
Step-by-step explanation:
Answer:
1) x = 30
2) x = 11.6
Step-by-step explanation:
1) 2x = 4x - 60 (vertical angles are equal)
subtract 4x from each side of the equation:
-2x = - 60
divide both sides by -2:
x = 30
2) 7x + 16 + 3x + 48 = 180° (supplementary angles add up to 180°)
combine like terms:
10x + 64 = 180
subtract 64 from both sides of the equation:
10x = 116
divide both sides by 10:
x = 11.6
Answer:
Try subtracting 585 to 20
Step-by-step explanation
then after you dom that times 360 and 20
Well in order to find the slope the equation should be in y= mx +b format, where m=slope
to do this you take your equation,
7x=-3y+15
and notice how the x and y are in the wrong position ,
add the 3y to both sides and subtract 7x from both sides
7x=-3y+15
+3y +3y
7x+3y=15
-7x. -7x
3y=-7x+15
now we need the y to be by itself so we divide the entire equation by 3 and get
y=-7/3x+5
so -7/3 or 2.33 or 2 1/3 would be the slope, the slope of parallel lines are equal
First calculate the slope by change in y over change in x
it’s -0.334
then find y intercept
-6
so all together
-0.334x-6
