3a + 2(4a - 1) = 9.
Distributive property.
3a + 8a - 2 = 9
Combine like terms.
11a - 2 = 9
subtract +2 on both sides.
11a - 2 = 9
+2 +2

Hi!
The correct answer to this <span>expression is y=9 if the equation is y-8+2=3 or y=19 if the equation is y-8</span>×2=3.
To get y=9 you need to add 2 to -8 to get -6, then you need to find the number that when subtracted by 6 equals 3 and that number is 9.
To get y=19 you need to multiply -8 by 2 to get -16, then you need to find the number that when subtracted by 16 equals 3 and that number is 19.
If it is neither of these answers then it is y-8 because you are replacing 2 with 3 in the expression.

Answer:
Angle 2=160
Angle 3=10
Step-by-step explanation:
The rhombus is made up of two isoceles triangle.
Angle 1 measures 160.
Since the triangle is a isoceles triangle, the opposite angles of the congruent sides is equal angles to each other.
So the reamaing angles in the top triangle are equal so we can use this equation
Remeber that triangle maximum degree it can hold is 180
We have two congruent triangle side they share Three sides. SSS
This means the corresponding angle of Angle 1 is Angle 2.
Angle 2=Angle 1 by CPCTC.
Angle 2=160
Angle 3 corresponds with one of the remaining congruent angles so it measures
10.
