Answer:
So we have this equation:
2 (3x-2) - 4x = 5x + 2
You can first operate the parenthesis, knowing that a(b+c) = ab + ac (conmutative)
2(3x-2) - 4x = 5x + 2
2 * 3x - 2 * 2 - 4x = 5x + 2
6x - 4 -4x = 5x + 2
Now, we can operate the x:
6x - 4 -4x = 5x + 2
2x - 4 = 5x + 2
And sum 4 in both sides and substract 5x in both too.
2x - 4 = 5x +2
2x - 4 + 4 - 5x' = 5x + 2 + 4 -5x
Now we can operate:
-3x = 6
And we can divide by -3 the two sides...
x = 6/-3 = -2
Answer:
x = 62
Step-by-step explanation:
Since 2 sides are congruent then the triangle is isosceles.
Thus the 2 base angles are congruent.
The sum of the 3 angles = 180°
x = 
= 
= 62
Answer:
17 miles
Step-by-step explanation:
20 - 3 = 17
(i may have misunderstood the question, if its $4 every mile then its 5 miles maximum)
<span>7x+15=2x+19
Subtract 2x from both sides
5x+15=19
Subtract 15 from both sides
5x=4
Divide 5 on both sides
Final Answer: C.) x= 4/5</span>
Answer:
C
Step-by-step explanation:
A cube has 6 square faces
