For this case, the first thing we must do is define variables.
 We have then:
 x = number of dimes
 y = number of quarters
 We write the system of equations:
 0.10x + 0.25y = 4.55
 x = y
 Solving the system we have:
 x = 13
 y = 13
 The value of the dimes is:
 (0.10) * (13) = 1.3 $
 Answer:
 
The value of only the dimes is:
 
1.3 $

Answer:

The intensity of the first earthquake is 6.31 times the second one

Step-by-step explanation:

The given formulae is M=log(\frac{I}{S})

Here for both the earthquakes the value of S is same.

Let the Intensity of the first earthquake be I1 and the second be I2.

Given M1=7.5

M2=6.7

Now  M1=log(\frac{I1}{S})------1

M2=log(\frac{I2}{S})-----2

Now subtract 1 and 2 we get

M1-M2=log(\frac{I1}{I2})

I1/I2=10^{M1-M2}

I1=I2(10^{0.8}

I1=I2*6.31

“kilo-“ means “thousand.” A kilogram is 1,000 grams.
5 kg = 5,000 g
5,000 g × (1 pizza)/(300 g) = 5,000/300 pizzas = 16⅓
16 pizzas
