Answer:
-4
Step-by-step explanation:
Let's put this in math notation. We can call the number x:
9x+4=8x
Subtract 8x from both sides:
x+4=0
Subtract 4 from both sides:
x=-4
Answer:
2/3a^5
Step-by-step explanation:
we know that 2/7x2/7x2/7 = 8/27
a^15 cube will be a^5
because we know (2^3)^2 = 2^6
so (a^5)^3 = a^15
2/3a^5
Answer:
x=6
Step-by-step explanation:
its an equilateral triangle so all sides are the same measure
9=3x-9
18=3x
x=6
Answer: the value of x is 2
Step-by-step explanation: because 5 x 2 = 10 and 10 + 25 = 35
3x - 2y = 6
-2y = -3x + 6
y = (-3/-2)x + 6/-2
y = 3/2x - 3
