Answer:
x=-2
Step-by-step explanation:
It is a straight line when x=-2 :)
The pair of numbers that would be in the columns, considering the proportional relationship, is given as follows:
20 would be in the column for 2, and 60 would be in the column for 6.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a special linear function, with intercept having a value of zero, in which the output variable is obtained with the multiplication of the input variable and the constant of proportionality k, as shown as follows:
y = kx
The table is extended to represent more equivalent ratios for 2:6, hence the constant of the relationship is given as follows:
k = 6/2 = 3.
Hence the equation is:
y = 3x.
The values given by each column are given as follows:
When x = 20, the numeric value of the relationship is of:
y = 3 x 20 = 60.
Hence the first option is correct.

Answer:
D. 
Step-by-step explanation:
Given
Required
Determine its equivalent
<em>From the list of given options, the correct answer is</em>
This is shown as follows;
Multiply both sides by 
Open Bracket
Subtract x from both sides
Multiply both sides by -1
Reorder
<em>Hence, the correct option is D</em>
Answer:
8
Step-by-step explanation:
8x3=24
minus 15 is 9
half of 8 is 4
plus 5 is 9
therefore, the answer is 9.
Answer:
Isolate the variable by dividing each side by factors that dont contain the variable.
