Step-by-step explanation:
3a-3(a+2)=10
3a-3a-6=10
+3 +3
6a-6=10
+6 +6
6a=16
Answer:
x - 3
Step-by-step explanation:
let's call the unknown number x to express its value that's three less than actual number we say x - 3
here the equation of path is -2x-7=y
let us find slope of this line by using y=mx+b
so slope m=-2
now new path is perpendicular to this path.
product of slopes of perpendiculars is -1
so slope of new path is 1/2
now it passes through (-2,-3) with slope 1/2
using y=mx+b to get value of b
-3=1/2(-2) +b
b=-2
plugging m=-1/2 and b=-2 in y=mx + b to get the final equation as
y=(-1/2) x -2 is the equation of new path
Answer:
5
Step-by-step explanation:
When two lines are crossed by another line (the transversal), the pair of angles on the opposite and inner side of each of those two lines
are called Alternate Interior Angles. Therefore 5 is the alternate interior angle to 4.
