Answer:
we need to add a²=6² to both sides of in order to rewrite in the form .
Step-by-step explanation:
Given the equation
First of all, we need to divide both sides by -3 to simplify it
i.e.
In order to rewrite in the form , we need to add a²=6² to both sides
so
Therefore, we need to add a²=6² to both sides of in order to rewrite in the form .
Let me answer those two questions in the reverse order.
1). How it can be solved:
7x + 5 = 3x - 11
Subtract 3x
from each side: 4x + 5 = - 11
Subtract 5
from each side: 4x = - 16
Divide each side
by 4 : x = - 4
2). The answer is x = - 4 .
-4 is called the 'solution' to the equation, because that's the number
that 'X' MUST be. If it's any other number, then the equation is not
a true statement.
For this equation I used the fact that S and U are congruent (because Line ur and rs are equal and lines UT and TS are equal. All the interior angles need to add to 360 degrees. U+R+S = 340 so T has to equal 20 degrees.
Answer:
x = 40°
Step-by-step explanation:
Both triangles can be regarded as similar triangles. Therefore, their corresponding angles would be congruent to each other.
Thus:
x = 180° - (75° + 65°)
x = 180 - 140
x = 40°
A. 1540-1000= 540 (amount of the bonus).. 540 ÷30(amount per sale) = 18
