Answer:

\sf \log_b(75)=4.317

\sf \ln (20)=2.9957

Step-by-step explanation:

<u>Question 1</u>

Given:

  \sf \log_b(3)=1.099

  \sf \log_b(5)=1.609

To evaluate \sf \log_b(75),  replace 75 with (5 × 5 × 3):

\implies \sf \log_b(5 \cdot 5 \cdot 3)

\textsf{Apply the Product log law}: \quad \log_axy=\log_ax + \log_ay

\implies \sf \log_b5+\log_b5+\log_b3

Substitute the given values to solve:

\implies \sf 1.609 + 1.609 + 1.099=4.317

<u>Question 2</u>

Given:

  \sf \ln(4)=1.3863

  \sf \ln(5)=1.6094

To evaluate ln(20) replace 20 with (4 × 5):

\implies \sf \ln (4 \cdot  5)

\textsf{Apply the Product log law}: \quad \ln xy=\ln x + \ln y

<em />\implies \sf \ln (4)+\ln (5)

Substitute the given values to solve:

\implies \sf 1.3863+1.6094=2.9957

Help please! this is my third time posting this!! T.T
ArbitrLikvidat [17]

Answer:

see below

Step-by-step explanation:

24 - 3 x = -27

Subtract 24 from each side

24-24 - 3 x = -27-24

-3x =-51

Divide each side by -3

-3x/-3 = -51/-3

x = 17

Check

24 -3(17) = -27

24 -51 = -27

-27 = -27

Suzie's Nursery is having a sale on two kinds of plants, venus fly traps and bonsai trees.
ANTONII [103]

Answer:

Venus fly trap = 12

Bonsai tree = 17

Step-by-step explanation:

Given that :

Venus fly trap = $3per plant

Bonsai tree = $5 per plant

Number of plants sold = 29

Total cost of plant sold = $121

Let venus fly trap = x ; bonsai tree =y

x + y = 29 ___ (1)

3x + 5y = 121 ____(2)

From (1) :

x = 29 - y

In (2):

3(29 - y) + 5y = 121

87 - 3y + 5y = 121

87 + 2y = 121

2y = 121 - 87

2y = 34

y = 34/2

y = 17

x = 29 - 17

x = 12

Hence,

Venus fly trap = 12

Bonsai tree = 17
