Answer:
9 cookies
Step-by-step explanation:
Answer:
To solve, we need to isolate the variable
The first step is to subtract 18 from both sides to "reverse" the addition
-6x+18=-6
-6x=-24
The second step is to divide -6 on both sides to "reverse" the multiplication
-6x=-24
x=4
Hope this helps! :)

Answer:
60°
140°
Step-by-step explanation:
From the given figures,
a. we use the concept of alternate angles.
Two parallel lines cut by a transversal will have equal alternate angles;
So;
6x + 12 = 7x + 4
collect like terms and solve for x;
6x - 7x = 4 - 12
-x = -8
x = 8
Now, 6x + 12 = 6(8) + 12
= 48 + 12
= 60°
b. Here we use alternate angles and angles on a line;
4x is an alternate angle to that angle to the left of 13x + 10
And sum of angles on a line = 180
4x + 13x + 10 = 180
17x = 170
x = 10
Now, 13x + 10 = 13(10) + 10 = 140°
