Answer:

Step-by-step explanation:You need to understand that you're solving for the average, which you already know: 90. Since you know the values of the first three exams, and you know what your final value needs to be, just set up the problem like you would any time you're averaging something.

Bill notes that his apple tree is 4/5 the size of his pear tree is apple tree is 4 M tall how tall is the pear tree

e-lub [12.9K]

1) Given that the apple tree is 4/5 pear tree we can write

Apple Tree size = 4/5 Peartree

Apple tree= 4m

2) So we can write the following expression for that:

$\begin{gathered} Apple=\frac{4}{5}P \\ 4=\frac{4}{5}_{}P \\ 4P=20m \\ P=\frac{20}{4} \\ P=5 \\ \\ \end{gathered}$

So the Pear tree is 5 meters tall, and the apple tree is 4/5*5 = 4 m

Which complex number is equivalent to (5 + 12i) − (9i2 − 6i), where i = <br> −1<br> ?

Alchen [17]

Answer:

14 + 18i

Step-by-step explanation:

$(5 + 12i) - (9 {i}^{2} - 6i) \\ = (5 + 12i) - (9 \times (- 1) - 6i) \\ = (5 + 12i) - ( - 9 - 6i) \\ = (5 + 12i) + ( 9 + 6i) \\ = 5 + 12i + 9 + 6i \\ \red { \bold{ = 14 + 18i}}$
