Answer:
X= -10
Step-by-step explanation:
15=3x-15
Minus the numbers on the other side of the variable
15=3x-15
-15 -15
=0 -30
In algebra the - before a number gets counted as a negative so -15 minus 15 = -30
Then since we still have 3x we divide it by -30 because its being tiems by a number we cant see
so -30/3 = -10
Thats how we found X.
Answer:
Solve for x
Step-by-step explanation:
we already know that 30 minus 15 is 15 so something times 3 equals 30. 10x3=30. so x = 10.
15 =3(10)-15
15= 3(10) -15 =30 -15
15 = 30 - 15
15=15
So, again, the answer is 10.

Your first question does not provide enough information
The second question would be
a^5
or
√(a^10)
Scalene, and isosceles both have and acute angles in them
That’s 7 to the power of 3 which means 7x7x7=343. Hope this helps mark Brainest
