The temperature on Thursday morning would be -13°F.
Since the temperature decreased throughout the night, this is a subtraction problem.
-5 - 8 = - 13
Answer:
The answer is 9.
Step-by-step explanation:
Answer:
27 =x
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the same side of the large triangle.
x+8 10
------- = -------------------
2x-5 14
Using cross products
14 (x+8) = 10 (2x-5)
Distribute
14x+112 = 20x-50
Subtract 14x from each side
14x-14x +112 = 20x-50-14x
112 = 6x-50
Add 50 to each side
112+50 = 6x-50+50
162 = 6x
Divide by 6
162/6 =6x/6
27 =x
Answer:
the last one is 30
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Let x be a number.
The statement can be interpreted as:
- 5 is subtracted <u>from</u> a number : x - 5
- A number is greater than 6 : x > 6
- When 5 is subtracted <u>from</u> 3 times a number, the result is greater than 6 : 3x - 5 > 6
And then we simplify 3x - 5 > 6:
- 3x - 5 > 6
- 3x > 11
- x > 11/3
- x > 3.666...
To get the smallest whole number satisfying the inequality above, we can take the "ceiling" of 3.66 which is 4.
Note:
The ceiling of a number is the nearest integer (or in this case, nearest whole number) of a number. It can be denoted by ceil(x).
For example, the ceiling of 0.1 is 1. The ceiling of 5 is 5 since 5 itself is a integer.
