Answer:
A. -100
Step-by-step explanation:
1.) To single out x, follow the opposite operation on both sides. Firstly, we begin with:
X/5 + 6 = -14
Then the opposite operation from addition is subtraction, therefore:
X/5 + 6 - 6 = -14 - 6,
X/5 = -20
Then the opposite operation from division is multiplication, therefore:
X/5 x 5 = -20 x 5
X = -100
Answer:
1/15
Step-by-step explanation:
First you must figure out your total outcomes, int the problem it said ten. Than take the number of students and put the number of students over the number of outcomes. This will tell you the probability of drawing one student. Next you must subtract 1 student and one member from your original equation. This is because you have assumed that the first drawing had a favorable outcome. So that leaves you with 2/9. Next you must multiply both the first fraction (3/10) and the second fraction (2/9) to come up with the total probability of the event occurring.

Li can walk 6 miles. if you divide 135 and 45, you'll get 3. finally, if you multiply 2 and 3, you'll get 6. So, in total, Li walks 6 miles.
