Given the choices, the best fitting answer would be the first one. "2 loaves of bread and 4 batches of muffins". I figured this out by multiplying the amount of flour and sugar required for each loaf of bread and batch of muffins
X can be from -1.6 to -1.7 or x can be from -3.3 to 3.3
The problem statement gives you the relationship between their speeds, and it gives you information you can use to find their total speed. You solve this by finding the total speed, then the proportion of that belonging to Bill.
The total speed is (120 mi)/(3 h) = 40 mi/h.
The speed ratio is ...
... Bill : Joe = 3 : 1
so the speed ratio Bill : Total is ...
... 3 : (3+1) = 3:4.
Bill's speed is (3/4)×(40 mi/h) = 30 mi/h.
Subtract 20 and 10. To get your answer
We have the formula A = (h x b) / 2, where A is the area of the triangle, h is the height of the triangle, b is the base of the triangle;
So, 32 =(8 x b) / 2;
Then, 64 = 8 x b;
b = 64 ÷ 8;
b = 8 inches;
