You buy plans in brainly.
Step-by-step explanation:
When we have exponents multiplied with the same base we add them so 5^5*5^10=5^15
Answer:
16-x*(-7)=-154
7x =-154-16
7x/7=-170/7
X=-24.29
Step-by-step explanation:
Let x represent "my number"
(6 • 2 - 2x + 16) + (4 • 2 + 7x - 55)
(-2x + 16 + 6 • 2) + (7x - 55 + 4 • 2)
(-2x + 16 + 12) + (7x - 55 + 8)
-2x + 28 + 7x - 47
-2x + 7x + 28 - 47
5x + (-19)
5x - 19
So the answer is 5x - 19.
