Answer: 28
Step-by-step explanation: In this problem, we're given information about the parts of a segment and we're asked to find the value of x.
To find the value of x, we can use the <em>segment addition postulate</em>.
Looking at the diagram, it should make since that RS + ST = RT.
So 4x + 3x + 11 = 60 or 7x + 11 = 60.
Subtracting 11 from both sides and solving for x, we get x = 7.
Since RS is 4x, we can substitute a 7 in for x to get 4(7) or 28.
Answer:
The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8
The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2
You can check your answer by plugging in your answer to the variable and making sure both side equal each other
Step-by-step explanation:
The first one: the 5 should be - from both side so you get k=-8
The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2
Remember you always want to get the variables by themselves.
Sorry that was a lot. Hope it helps!
Y = 30 - 2(2)
y= 30 - 4
