1/7 work takes 2days
6*1/7=6/7 work takes 6*2days=12days
30 men takes 12 days to finish the rest of work (6/7)
18 men takes 18*12/30= 7.2days

Pls help 10 pnt <br> X=<br> 6<br> 3.75<br> 2
kolezko [41]

4 × ( x + 4 ) = 3 × ( 3 + 5 )

4 × ( x + 4 ) = 3 × 8

Divide both sides by 4

x + 4 = 3 × 2

x + 4 = 6

Subtract both sides 4

x = 2

Select the correct answer.
marishachu [46]

Answer:

M = \log(10000)

Step-by-step explanation:

Given

M = \log(\frac{I}{I_o})

I = 10000I_o ---- intensity is 10000 times reference earthquake

Required

The resulting equation

We have:

M = \log(\frac{I}{I_o})

Substitute the right values

M = \log(\frac{10000I_o}{I_o})

M = \log(10000)

Mei does 6 problems in 18 minutes. How many can she complete in 12 minutes
Dmitriy789 [7]
Do cross multiplication

  <u>6</u>  =  <u>x</u>
 18    12

Now cross multiply

(6)(12) = (18)(x)

       72 = 18x

Divide both sides by 18
     
    
     <u>72</u>  = <u>18x</u>
     18      18

      4   = x

So tMei can complete 4 problems in 12 minutes.

Combine like terms: 8v-6j-10v+8j
diamong [38]
Just put them together. The subtraction sign is a negative sign. First step: 8v-10v= -2v Second Step: 8j-6j= 2j So your final answer would be: 2j-2v
