21 = 5n-2(n-3)

21 = 5n-2n+6

21-6 = 3n

n=15/3

n=5

5=n because you multiply -2 times n then -3 then you add -2n with 5n then subtract 6 from both sides and finally divide by 3

Tadeo is a beekeeper. The table shows the weekly number of bees producing honey in a new hive. Which expression gives the number
Afina-wow [57]

The exponential equation that gives the number of bees in week 12 is of:

y = 4(3)^{11} = 708588

<h3>What is an exponential function?</h3>

It is modeled by:

y = ab^x

In which:

  • a is the initial value.
  • b is the rate of change.

In this problem, considering that the initial week is the first, and the value triples every week, the expression for the number of bees after x weeks is given by:

y = 4(3)^{x - 1}

Hence, after 12 weeks, the expression is:

y = 4(3)^{11} = 708588

Solve the following inequality for y.<br> 18x + 6y &gt; 12
Murljashka [212]

Answer:

12

Step-by-step explanation:

Simplifying

18x + -6y = 12

Solving

18x + -6y = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6y' to each side of the equation.

18x + -6y + 6y = 12 + 6y

Combine like terms: -6y + 6y = 0

18x + 0 = 12 + 6y

18x = 12 + 6y

Divide each side by '18'.

x = 0.6666666667 + 0.3333333333y

Simplifying

x = 0.6666666667 + 0.3333333333y

Please help !!!! Please help!!!!! I gave extra points, if you put a link I will report you !

Since you have a angle number of 23 and you see the tiny square that means it’s equal to 90 up top and add 23 and 90 together and then subtract that by 180 to get all 3 angles in the triangle and then just use that to find the other line that’s 180.
