Answer:
n = 30
Step-by-step explanation:
4(n - 7) - (2- 5n) = 8n ← distribute parenthesis on left side
4n - 28 - 2 + 5n = 8n
9n - 30 = 8n ( subtract 8n from both sides )
n - 30 = 0 ( add 30 to both sides )
n = 30
The answer for the question is 97
Answer:
x = 13 1/2 or 13.5
Step-by-step explanation:
Flip Equation
-38 - 12x = -200
-12x -38 = -200
Add 38 to both sides
-12x -38 + 38 = -200 + 38
-12x = -162
Divide
-12x/-12 = -162/-12
x = 27/2
Simplify
27/2 = 13 1/2
x = 13 1/2
Answer:
Option B is correct.
Step-by-step explanation:
Given: RSTU is a parallelogram.
By definition of parallelogram, two pairs of opposite sides are congruent in length.
⇒
and 
In triangle RST and triangle TUR

[Side]
[Common side]
SSS(Side-Side-Side) postulates states that if three sides of one triangle are congruent to three sides of other triangle, then the triangles are congruent.
then, by SSS postulates we have;
