So,
0.2(n - 6) = 2.8
Distribute.
0.2n - 1.2 = 2.8
Add 1.2 to both sides.
0.2n = 4
Divide both sides by .2.
n = 20
Check.
0.2(20 - 6) = 2.8
Simplify inside parentheses.
0.2(14) = 2.8
Multiply.
2.8 = 2.8 This checks.
S = {2.8}

vertical stretch by factor of 10
Answer:
b = -2
Step-by-step explanation:
Given expression:
9(b - 4) - 7b = 5(3b -2)
Using distributive properties, open the parentheses;
9b - 36 - 7b = 15b - 10
2b - 36 = 15b -10
collect like terms;
2b - 15b = - 10 + 36
-13b = 26
Divide both sides by -13;
b = -2

Answer:
x = 8
m<ABE = 50°
Step-by-step explanation:
Since BE is a bisector of <ABD, it implies that two angles, <ABE and <DBE formed are equal.
Given that m<ABE = (6x + 2)°, and m<DBE = (8x - 14)°, therefore:
6x + 2 = 8x - 14
Solve for x
-2x + 2 = -14 (subtracting 8x from both sides)
-2x = -16 (subtracting 2 from both sides)
x = 8 (dividing both sides by -2)
m<ABE = (6x + 2)°
Replace x with 8
m<ABE = 6(8) + 2 = 48 + 2
m<ABE = 50°
