Subtract 4x from both sides
4x +2 = 7x - 13 would then simplify to
3x - 13 = 2 ( you can switch the problem around as long as you dont switch the variables around )
then you have to + 13 which simplifies to
3x = 15
then you divide by 3 which equals
x=5
Answer:
Step-by-step explanation:
All the sides are complete, hence we can use the information given to find just 1 triangle
Triangles
From the given information, we have that:
m<B = pi/6 = 30 degres
c = 10
b = 5
This shows that we can use the cosine rule to find the third side b of the triangle. Since all the sides are complete, hence we can use the information given to find just 1 triangle

The answer is 12. You find this by counting all of the numbers to the right of the line (referred to as "leaves" in this stem-and-leaf plot)
The numbers given in the problem above are part of an arithmetic sequence with first and sixth terms equal to -21 and -36, respectively. Firstly, calculate for the common difference (d).
d = (-36 - -21) / (6 - 1) = -3
The arithmetic mean is calculated by adding -3 to the term prior to it.
a2 = -21 + -3 = -24 a3 = -24 + -3 = -27
a4 = -27 + -3 = -30 a5 = -30 + -3 = -33
Thus the four arithmetic means are -24, -27, -30, and -33.
