The answer is 320.
If 16 = x / 20, then x = 320
Multiply both sides of the equation by 20:
20 * 16 = 20 * x / 20
Multiply the terms on the left side of the equation:
320 = 20x/20
320 = 20/20 * x
Simplify the rigth side of the equation:
320 = 1 * x
320 = x
Therefore, x = 320
The answer is: if x represents the number of pencils per box, solve the equation 8x+4=196
Answer:
A linear relationship (or linear association) is a statistical term used to describe a straight-line relationship between two variables. Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b. Linear relationships are fairly common in daily life.

Answer:
x = 19
A = 30°
B = C = 75°
Step-by-step explanation:
In an isosceles triangle, the angles opposite the congruent sides have the same measures.
A = B
3x +18 = 7x -58
76 = 4x . . . . . . . . add 58-4x
19 = x . . . . . . . . . divide by 4
Then the equal angles measure ...
A = B = 3(19) +18 = 75
C = 2(19) -8 = 30
Angles A, B, C measure 75°, 75°, 30°, respectively.
_____
<em>Alternate solution</em>
The sum of angles in a triangle is 180°, so you could write ...
(3x +18) +(7x -58) +(2x -8) = 180
12x = 228 . . . . . add 48
x = 19 . . . . . divide by 12
