In order to find constant of proportionality, you have to use the equation, x(?)=y
The ? being the number to plug in, which would be 1/4 in this case. 8 times 1/4 is equal to 2 and so on.

1. Which are true of x = log10 31,500? Select all that apply.

ziro4ka [17]

Given:

$x=\log_{10}31,500$

To find:

Select the true statements from the given options about the given value.

Solution:

We have,

$x=\log_{10}31,500$

It can be written as

$x=\log_{10}(2^23^25^37)$

$x=\log_{10}(2^2)+\log_{10}(3^2)+\log_{10}(5^3)+\log_{10}(7)$ $[\because \log(ab)=\log a+\log b]$

$x=2\log_{10}2+2\log_{10}3+3\log_{10}5+\log_{10}(7)$

$x=2\left(0.30105\right)+2\left(0.47712\right)+3\left(0.69897\right)+0.8451$

$x=4.49835$

Clearly, the value of x lies between 4 and 5. So, $x>4$ and $x$ .

Therefore, the correct options are C and D.

2r-3.1=1.7 solve each equation check your soultion plz help step by step plz

professor190 [17]

2r-3.1=1.7 add 3.1

2r=1.7+3.1 divide by 2 to isolate r

2r/2=4.8/2

r=2.4

check

2(2.4)-3.1=1.7

4.8-3.1=1.7

1.7=1.7

4t+3.5=12.5 sub 3.5

4t=12.5-3.5 divide by 4

4t/4=9/4

t=9/4

check

4(9/4)+3.5=12.5

9+3.5=12.5

12.5=12.5

8m-5.5=10.1 add 5.5

8m=10.1+5.5 divide by 8

8m/8=15.6/8

m=1.95

check

8(1.95)-5.5=10.1

15.6-5.5=10.1

10.1=10.1
