Answer:
34
Step-by-step explanation:
Since AD is a straight line the sum of ABC and DBC would be equal to 180°
2x + 4 + 3x + 6 = 180 add like terms
5x + 10 = 180 subtract 10 from both sides
5x = 170 divide both sides by 5
x = 34
Answer:
The mistake there is the expression shown is not in PEMDAS.
<em>PEMDAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on multiplication & division and at last addition and subtraction.</em>
Step-by-step explanation:
1 + 4 x 9 4 x 9 = 36
1 + 36 36 + 1 = 37
37
Always remeber to use multiplication first!
Answer:
infinite solutions
Step-by-step explanation:
Given
x + 3 + 2x = 4 + 3x - 1 ( simplify both sides )
3x + 3 = 3x + 3
Since the equation is the same on both sides.
This indications the equation has an infinite number of solutions
Yes, I believe that is correct.
Well to solve for r, what you would need to do is make up an equation based on the expressions that represent the segments of the line in the image.
JK represents the first aspect of the line and is equal to 6r.
Likewise, KL represents the second component of the line and is equal to 3r.
We also know the total value from the first point to the last one, and that is 27.
Now simply add the first 2 expressions that represent the segments of the line and make it equal to the total length of the line, 27 and then solve for r.
6r + 3r = 27
9r = 27
r = 27/9
r = 3.
So now we know that JK is 6 • 3 = 18 and KL is 3 • 3 = 9, thus adding both together will give a value of 27, 18 + 9 = 27.
The solution is C.3
