You would turn the 15% into a decimal which is .15 then multiply .15 by 4.25. After multiplying those together add 4.25 to the answer.
Step-by-step explanation:
Since X is given to you (in this case, it’s 7), all you have to do is plug it into the equation.
1. -2(7) + 10
When a variable or a number is directly outside a number, it means you should multiply the two numbers, no matter what.
Now that we know this: -2 * 7 = (-14) When a negative is multiplied by a positive, it turns out negative.
2. (-14) + 10: Let’s say (for instance), that I owe 14 dollars to a friend. If I pay 10 of it, how much do I owe my friend? It would be -4 because you’re still in debt, and haven’t payed your friend all of her 14 dollars back.
3. You should come up with an answer of (-4) because of all of the steps given.

Step-by-step explanation:
Consider splitting this figure into two mini rectangles and a triangle, each of given lengths;
![Dimensions of Rectangle 1 - Height ; 5 mi, Length ; 7 mi,\\Area of Rectangle 1 - Height * Length = 5 mi * 7 mi = 35 mi^2\\\\Dimensions of Rectangle 2 - Height ; 18 mi, Length ; 8 mi,\\Area of Rectangle 2 - Height * Length = 23 mi * 8 mi = 184 mi^2\\\\Dimensions of Mini Right Triangle - Height ; 11 mi, Base ; 8 + 5 = 13 mi,\\Area of Mini Right Triangle - 1 / 2 * Base * Height = 1 / 2 * 13 mi * 11 mi = 71.5 mi^2,\\\\Area of Figure = 35 mi^2 + 184 mi^2 + 71.5 mi^2 = 290.5 square miles](https://tex.z-dn.net/?f=Dimensions%20of%20Rectangle%201%20-%20Height%20%3B%205%20mi%2C%20Length%20%3B%207%20mi%2C%5C%5CArea%20of%20Rectangle%201%20-%20Height%20%2A%20Length%20%3D%205%20mi%20%2A%207%20mi%20%3D%2035%20mi%5E2%5C%5C%5C%5CDimensions%20of%20Rectangle%202%20-%20Height%20%3B%2018%20mi%2C%20Length%20%3B%208%20mi%2C%5C%5CArea%20of%20Rectangle%202%20-%20Height%20%2A%20Length%20%3D%2023%20mi%20%2A%208%20mi%20%3D%20184%20mi%5E2%5C%5C%5C%5CDimensions%20of%20Mini%20Right%20Triangle%20-%20Height%20%3B%2011%20mi%2C%20Base%20%3B%208%20%2B%205%20%3D%2013%20mi%2C%5C%5CArea%20of%20Mini%20Right%20Triangle%20-%201%20%2F%202%20%2A%20Base%20%2A%20Height%20%3D%201%20%2F%202%20%2A%2013%20mi%20%2A%2011%20mi%20%3D%2071.5%20mi%5E2%2C%5C%5C%5C%5CArea%20of%20Figure%20%3D%2035%20mi%5E2%20%2B%20184%20mi%5E2%20%2B%2071.5%20mi%5E2%20%3D%20290.5%20square%20miles)
