Answer:
The 3rd option
Step-by-step explanation:
If we find X then this would become a Mult. problem
Formula to find the slope of line between two points:
(y2-y1)/(x2-x1)
(20-50)/(25-10) = -30/15 = -2
Therefore, the slope would be -2.
Answer:
15$
Step-by-step explanation:
Step 1: First determine the value of the whole amount, which is 50.
Step 2: Determine the percentage, which is 30.
Step 3: Convert the percentage 30% to its decimal form by dividing 30 into 100 to get the decimal number 0.3:
30/100 = 0.3
(Dividing into 100 is the same as moving the decimal point two places to the left.)
30.0 → 3.00 → 0.30
Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount:
0.3 x 50 = 15 (answer).
