Answer:
145
Step-by-step explanation:
We will let x equal our unknown number. So:
(x + 5)/2 = 75
Now we can solve for x
We can first multiply both sides of the equation by 2. This will get rid of the fraction on the left side:
x + 5 = 75 * 2 ----->
x + 5 = 150
Next, subtract 5 from both sides:
x + 5 - 5 = 150 - 5 ----->
x = 145
Yes! The lengths of each side must be less than the sum of the other two lengths. It looks like this:
4+4>7
7+4>4
4+7>4
Answer:
The RIGHT answer is: x = −1
Step-by-step explanation:
If the two of you can wash 1 car in 6 minutes:
It will take you 10 minutes to wash the car alone
take your friend 15 minutes to wash the car alone
Let the duration you can work be represented by y
Let the duration your friend can work be represented by x
You can wash a car 1.5 times as fast as your friend
That is, y = 1.5x
Working together, the two of you can wash 1 car in 6 minutes
This can be represented by the equation
Substitute x = 1.5y into the equation above
It will take you 10 minutes to wash the car alone
Substitute y = 10 into x = 1.5y
x = 1.5(10)
x = 15 minutes
It will take your friend 15 minutes to wash the car alone

Answer:
No.
Step-by-step explanation:
The two smallest sides must be greater than the biggest side when added up in order to form a complete triangle.
1+3 is 4, which is less than five, so the triangle wouldn't be connected.
Essentially, imagine a triangle where one line is too short to reach the other two, which is what was just explained--the smallest sides must add up to be greater than the biggest side in order to form a complete triangle.
