1 answer:
grigory [225]2 years ago
4 0

Answer:

10. 7n - 1 < -8

Isolate the variable, n. Do the opposite of PEMDAS. Treat the < as equal sign, what you do to one side, you do to the other. First, add 1 to both sides:

7n - 1 (+1) < - 8 (+1)

7n < - 8 + 1

7n < - 7

Isolate the variable, n. Divide 7 from both sides:

(7n)/7 < (-7)/7

n < -7/7

n < -1

n < -1 is your answer.

11. 3 > -7v + 4v

Combine like terms, then isolate the variable, v. First, add -7v and 4v together.

3 > (-7v + 4v)

3 > (4v - 7v)

3 > (-3v)

Isolate the variable, v. Divide -3 from both sides. Note that since you are dividing a negative number, you must flip the sign:

(3)/-3 > (-3v)/-3

3/-3 > v

-1 < v

v > -1 is your answer.

Complete the two-column proof. Given:x5+9=11 Given: x 5 + 9 = 11 Prove x=10 Prove x = 10 x5+9=11 x 5 + 9 = 11 a._______ x5=2 x 5
avanturin [10]

<u>Statement  </u>                                       <u>Reason</u>

<u>\frac{x}{5} +9 = 11\\          </u>    Given

Subtract 9 from both the sides

<u>\frac{x}{5} +9-9 = 11-9\\</u><u>       </u>    Subtracting same number will not        affect equation

\frac{x}{5}  = 2\\                           Simplification

\frac{x}{5}*5  = 2*5(\\                   Multiplying by 5 both the sides

x= 10                                                           By simplifying both the sides

Thus we solved the equation and got x =10 as answer.

Relative density was determined for one sample of second-growth Douglas fir 2 x 3 4s with a low percentage of juvenile wood and
Citrus2011 [14]

Answer:

0.03865

Step-by-step explanation:

Since the true density for the two types of trees are given, we would evaluate the average for both of them

Low percentage of juvenile wood density = 0.523 and 0.0543

Average density = 0.523 + 0.0543/2

Average density = 0.55015

Moderate percentage of juvenile wood density = 0.489 and 0.0450

Average density = 0.489 + 0.0450/2

Average density = 0.5115

Therefore, difference in true average density for the two woods are = 0.55015 - 0.51150

= 0.03865

Find the sum of the first 9 terms of the sequence. Show all work for full credit.
Kamila [148]
We can see the sequence goes by decreasing 9 on each number

so the numbers are

2, -7, -16, -25, -34, -43, -52, -61, -70

so adding all these numbers we get

2-7-16-25-34-43-52-61-70

= -306


hope this helped
