Well, in the first one, 2 degrees below zero is -2 degrees, and then it says that it dropped 14 degrees, which means it dropped -14 degrees, so to know the total amount it dropped you would just have to add -2 plus -14 which is -16 degrees, so your answer for the first question would be the last answer, -16 degrees.
For the second question, just know that whenever a negative number is BY ITSELF in parentheses, that means it is used like a positive number in the equation. So (-12) automatically becomes 12. Now, since the problem is asking for a SUM, (the answer to an ADDITION problem; when you add instead of subtract), you would turn that minus symbol to a plus symbol, and add normally to get your final answer; 30 + 12 = 42. To check if this is correct, just type in <span>30 – (–12) to a calculator and you'll get the same answer! :D
Hope this helps! :3</span>
Answer:
Equation: 4 1/4 + 1 3/4
Evaluation: 5 3/4
Step-by-step explanation:
So, Nora jobs 4 1/4 miles on Monday, which is 1 1/2 miles fewer than on Tuesday.
If this was 1.5 fewer miles, we need to add 1 1/2 and 4 1/4 to get our answer
We change the denominator on 1 1/2 to be 4. So, we multiply both sides by 2 and get 1 2/4
4 1/4 + 1 2/4 = 5 3/4
Answer:
$100
Step-by-step explanation:
We can see from the graph that the rate of change is $20. This is because for every increase in x, the value of y increases by $20.
Going from this, the value at x=4 is $80; this will make the value at x=5
80+20 = 100

Answer:
Step-by-step explanation:
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
Bringing like terms on one side
3 + 9 = 4.5x - 1. 5x
12 = 3x
12/3 = x
4 = x
9:15 is also equal to 3:5
