Step-by-step explanation:
DG is the total measurement of the line. M is a point inbetween D & G
2x + x - 2 = 7
Simplify. Combine likke terms
(2x + x) - 2 = 7
3x - 2 = 7
Isolate the x. First, add 2 to both sides
3x - 2 (+2) = 7 (+2)
3x = 9
Isolate the x. Divide 3 from both sides
(3x)/3 = (9)/3
x = 9/3
x = 3

3 is your answer for x

~<em>Where the Good Way Lies, Hope Unfolds</em>
Answer:
B. 12cm
Step-by-step explanation:
We can double check by plugging in the number. However, the question trys to trick you, by giving you the diametre, but in order for the formula to work (V=4
/3πr^3), we will divide the diametre by 2 (12 ÷ 2= 6),
--------------------------------------------------------------------------------------------------------------
Once we do that, we can double check, when you plug in your numbers your answer will be around 900 (904.78, to be exact, but the question asks for approximate diamtetre).

Have a good day :)
First of all, the left triangle is an equilateral triangle. Which means that all the interior angles are 60 degrees.
4w=60
w=15
Then all 3 sides are equal thus we can set up equation 3x-y=4y then simplify,
3x=5y
Going to the triangle on the right its isosceles we can set up equation 2x+50=180
2x=130
x=75
Substitute this back into equation above 3x=5y
5y=3*75
y=45
Therefore
x=75
y=45
w=15
Done!
