b. x can only equal 7.4.
c. x can equal –3.2 or –7.4.
d. x can equal –3.2 or 7.4.
we have
Step 1
Find the first solution (case positive)
Eliminate the parenthesis left side
Subtract both sides
Divide by both sides
Step 2
Find the second solution (case negative)
Eliminate the parenthesis left side
Adds both sides
Divide by both sides
therefore
the answer is the option C
x can equal –3.2 or –7.4
B. 70.7 centimeters
C. 6,361.7 centimeters
D. 141.4 centimeters
The table of values by the equation 4y - 2x = 16 is (d)
The table of values that complete the question is added as an attachment
The equation is given as:
4y - 2x = 16
Add 2x to both sides
4y = 2x + 16
Divide through by 4
y = 0.5x + 4
Set x = 0, 2 and 4
y = 0.5(0) + 4 = 4
y = 0.5(2) + 4 = 5
y = 0.5(4) + 4 = 6
So, we have:
x y
0 4
2 5
4 6
Hence, the table of values by the equation is (d)

The most effective strategies to subtract 563 from 192 are by rounding the number (Choice B) or by step-by-step addition and subtraction (Choice A), with rounding being the preferred method for ease of calculation.
To subtract 563 from 192, two effective strategies can be used. The first strategy (Choice B) simplifies the problem by rounding 192 to 200, subtracting to get 563 - 200 = 363, and then adding back the difference of 8 (since 200 - 192 = 8), resulting in the final answer of 363 + 8 = 371.
The second strategy (Choice A) is to add the constituent parts of 192, which are 100, 90, and 2, to perform step-by-step addition and subtraction. This method, however, is less efficient than the rounding technique and is prone to errors in a manual calculation process.
