Answer:

Step-by-step explanation:
To solve this problem, you must:
- Subtract 7 from both sides of the equation:

- Now, you can factor it. Choose two numbers whose sum -14 and whose product is 45. These numbers would be -9 and -5. Therefore, you obtain the following solution:

A) 3. 50+15+15+15= 95.
b) 4. 25+25+25+25= 100.
c) 7. 50+15+15+15+15+15+15+15= 155.
d) 6. 25+25+25+25+25+25= 150.
Answer:the answer is D.
Step-by-step explanation:
5(x)- -3(y) is 8. Make the negative into a positive if the equation looks like that. 4x5=20 + 3x-3=-9 so 20+-9= 11
6 and 7 because it is 6.32
Answer: It means Aria's vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.
Step-by-step explanation:
Since, Here d represents distance along the trail.
And, V(d) represents the vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.
If the distance along the trial is 3 km.
That is, d = 3
Then the vertical distance she walked from the top of the valley = V(3)
But According to the question,
V(3) < 3
Her vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.
In other words, For going 3 km along the trail her vertical distance from the top of the valley is less than 3.
