18 (m + 4/9) - 16 = 118 Get rid of the parentheses by multiplying 18 * M + 4/9
18M + 8 - 16 = 118 Subtract 8 - 16
18M - 8 = 118 Add 8 to both sides
18M = 118 + 8 Add 118 + 8
18M = 126 Divide 126/18
M = 7
Answer:
a(5) = 2 + 5^2 = 2 + 25 = 27
Step-by-step explanation:
This sequence is defined as a(n) = 2 + n^2.
Thus, a(1) = 2 + 1^2 = 2 + 1 = 3
Then a(5) = 2 + 5^2 = 2 + 25 = 27
A•a^7 = a^8 (add the power (n=1+7=8))
Solve:
(3x-2)^2-4x(2x-3)>=0
(3x-2)(3x-2)-8x^2+12x>=0
9x^2-12x+4-8x^2+12x>=0
The solution: x^2+4>=0
I hope I helped you with your solution! If you could give me brainliest, I would be very thankful!
Answer:
a. 90 pizzas
b. 12% decrease
Step-by-step explanation:
To receive a bonus, there must be 20% increase in the number of pizzas
Thus;
20% of 75 = 20/100 * 75 = 1500/100 = 15
So the number of pizza to be sold to receive the bonus will be 15 + 75 = 90
So now, we have 66 pizza sold today;
We can see that there was a decrease from 75
Percentage decrease will be;
(new value - old value)old value * 100%
= (66-75)/75 * 100%
= -9/75 * 100%
= -0.12 * 100% = -12%
This shows a 12% decrease
