The equation seems to be
1
-------- = 5 ^ (x + 4)
25
In that case, this is the solution, stept by step:
1) factor 25: 25 = 5^2
1
=> ----------- = 5^(x + 4)
5^2
2) invert 5^2
=> 5^(-2) = 5^(x+4)
3) Given that the bases are equal, the exponents also have to be equal:
=> - 2 = x + 4
3) transpose +4:
=> - 2 - 4 = x
=> x = - 6
Answer: - 6
2.57 + 5x = 25.92 is the equation and when you solve for x you would get x = 4.67
Answer:
3/10 + 4/10
1/2 + 1/5
1/10 + 3/5
Step-by-step explanation:
3/10 + 4/10 = 7/10 (add numerator and keep denominator)
1/2 + 1/5 = 5/10 + 2/10 = 7/10 (use equivalent fractions)
1/10 + 3/5 = 1/10 + 6/10 = 7/10
I hope this helped and please mark me as brainliest!
Answer:
3
Step-by-step explanation:
3,3,3,6,7,7
the mode is the number the occurs the most and 3 is there 3 times so it is the mode
Step-by-step explanation:
2/3 x - 1/9 x + 5 = 20
6/9 x - 1/9 x = 15
5/9 x = 15
x = 15 * (9/5) = 27.
