Answer:

same variable term on both sides

Step-by-step explanation:

Given

3x - 1 > 3x + 2 ( add 1 to both sides )

3x > 3x + 3 ( subtract 3x from both sides )

0 > - 3 ← not true, thus no solution

Because the variable term was the same on both sides then it is eliminated

the relationship between the relative size of an earthquake, S, and the measure of the earthquake on the Richter scale, R, is gi

omeli [17]

Answer:

Relative Size, S, is 1584.89

Step-by-step explanation:

The equation is $R=log_{10}(S)$

Where,

R is the measurement in Richter Scale
S is the relative size of the earthquare

It is given that in Richter Scale, an earthquake measured 3.2, so $R=3.2$ .

They want to know relative size, S, so we put given information in equation and solve for S:

$R=log_{10}(S)\\3.2=log_{10}(S)$

Converting to exponential form, we have:

$3.2=log_{10}(S)\\S=10^{3.2}\\S=1584.8932$

Rounding to nearest hundredth, we have:

$S=1584.89$

AC = 9x - 12, CD = 4x + 18, AD = ?

GrogVix [38]

If we assume that point C is somewhere on segment AD, then,

AD = AC + CD

AD = (9x-12) + (4x+18)

AD = (9x+4x) + (-12+18)

AD = 13x+6 is the answer

Fill in the missing digit to make the number divisible by

torisob [31]

Answer:

Step-by-step explanation:

6. 0 ,234,560 is divisible by 2.

7. 389,570 is divisible by 5.

8. 630,620 is divisible by 10.

9. 6+1+1+8+1=17 +(1)

611,811 is divisible by 3.

10. 5+2+5+4+3=19

multiple of 9 are 9,18,27,...

to make the sum 27 we have to add 8 to 19.

525,438 is divisible by 8.
