Answer:

x= 17

Step-by-step explanation:

5x-7=3x+27

move 3x to other side by doing the oppostie (subtracting 3x)

5x-7-3x=27

2x-7=27

move -7 to other side by adding it (to the other side)

2x= 7+27

2x= 34

divide by 2 (on both sides) to get x by itself

2x/2=34/2

x= 17

Answer:

$\sf \log_b(75)=4.317$

$\sf \ln (20)=2.9957$

Step-by-step explanation:

Question 1

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:

$\implies \sf 1.609 + 1.609 + 1.099=4.317$

Question 2

Given:

$\sf \ln(4)=1.3863$

$\sf \ln(5)=1.6094$

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

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

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

$\implies \sf \ln (4)+\ln (5)$

Substitute the given values to solve:

$\implies \sf 1.3863+1.6094=2.9957$

Why does a table with 3 legs not rock geometry question

hodyreva [135]

I'm assuming the table is triangle shaped, therefore has a leg on each end, and doesn't rock. or it could be circular and have 3 legs and not rock...

hope this helped :)

For which value of x is line l parallel to line m? A. 28 B. 62 C. 22 D. 68

Rudiy27

For line l parallel to line m, the interior angles on the same side of the transversal should add upto 180° or in better words, they must be supplementary.

So, we can write that,

(2x + 6)° and 130° are supplementary.

⇛ 2x° + 6° + 130° = 180°

⇛ 2x° + 136° = 180°

⇛ 2x° = 44°

⇛ x° = 22°

The value of x for which line l is parallel to line m,

$\large{ \boxed{ \bf{ \red{x = 22 \degree}}}}$

And we are done !!
