11) Tell which real number corresponds to the situation.
During a quiz, a person loses 1800 pts.
answer: -1800
12) Solve for y
z=yq
Answer: z-q=y
13) Solve using the multiplication principle
10x=-90
Answer: x= -9
14) Collect like terms
20w+w+14/19w
Answer: 413w
16) A mountain with a base of 10,573 below sea level rises 18,880 ft. What is the elevation above sea level of its peak?
Answer: 8,307
Fine except for 12. Since z = product of y and q,
y = z/q
I hope this helps. Thanks for asking.
I'm sorry, but there seems to be an error in your question. The numbers you provided for question 14 don't seem to add up correctly. Could you please double-check the equation you provided? Thank you.
To determine the real number that corresponds to the situation, we need to consider the given information. In this case, the person loses 1800 points. Since the person is losing points, the number will be negative. Therefore, the real number that corresponds to this situation is -1800.
To solve for y in the equation z = yq, we want to isolate y on one side of the equation. To do this, we can divide both sides of the equation by q to get y = z/q. So the answer is y = z/q.
In order to solve the equation 10x = -90 using the multiplication principle, we need to divide both sides of the equation by 10. This gives us x = -90/10, which simplifies to x = -9.
To collect like terms in the expression 20w + w + (14/19)w, we combine the terms that have the same variable, which in this case is w. So we have 20w + w + (14/19)w = 20w + 1w + (14/19)w. Adding these together, we get 21w + (14/19)w, which can be simplified as 21w + (14/19)w = (399w + 14w)/19 = 413w/19. Therefore, the answer is 413w.
To find the elevation above sea level of the peak of the mountain, we need to add the distance the mountain rises to the base. In this case, the mountain rises 18,880 ft above the base, which is already 10,573 ft below sea level. To find the total elevation above sea level, we add these two values: 10,573 + 18,880 = 29,453 ft. Therefore, the elevation above sea level of the peak is 29,453 ft.
