(3x+7)+(4x+9)=-58
first add like terms
7x+16=-58
subtract 16 from both sides
-7x=-74
divide -7 from both sides
x=10.6
its 10.6 units long
Answer:
no solution
Step-by-step explanation:
2x-5=8x+7-6x
2x-5=2x+7
-5=7
Not true so no solution
Answer:
D.
Step-by-step explanation:
Least value = 22 and greatest = 30
Arrange in order:
22 22 23 23 24 25 26 27 28 30
So the median is the mean of the middle 2:
= (24+25)/2 = 24.5.
Also Q1 = 23 and Q3 = 27
So the correct plot is D.
Answer:
x = 18
Step-by-step explanation:
To solve this problem, we can use the exterior angle theorem, which means the measure of an exterior angle is the sum of its remote interior angles. In this case, this would mean:
x + 72 = 5x
Since this gives us an equation, we can just solve for x:
x + 72 = 5x
72 = 4x
x = 18
