Answer:

x = 8

Step-by-step explanation:

These angles are alternate interior angles and m is parallel to n, so they're congruent, meaning that they're equal!

So we can make our equation:

6x - 2 = 46

6x = 48

x = 8

Hope this helps!

Answer:

x=8

Step-by-step explanation:

Since you have 2 parallel lines being cut by a transveral, the 2 angles formed will be congruent by the alternate interior angles theorem. Now we can solve this algebraically. You have one angle at 46 degrees, and another at 6x-2 degrees. You will need to set 46 equal to 6x-2, which gets you 8 for x.

They estimate that their current (older) fridge, which they got for free, costs them about $17 a month in electricity charges to
Eddi Din [679]

Step-by-step explanation:

Step one:

given

current (older) fridge

electricity charges= $17 monthly

maintenance costs= $220

let the number of months be x

and the total cost be yo

the expression for the cost for the old fridge is

yo=220+17x---------1

New  fridge

electricity charges= $6 monthly

costs=  $1,050

let the number of months be x

and the total cost be yn

the expression for the cost for the old fridge is

yn= 1050+6x---------2

Hence the system of equation for the situation is

yo=220+17x---------1

yn= 1050+6x---------2

Step two

for 10 years there are 12*10= 120 months

put x= 120 in both expressions and compare the total

yo=220+17(120)---------1

yo=220+2040

yo=$2,260

yn= 1050+6(120)---------2

yn=1050+720

yn=$1770

<u><em>Based on the analysis it will be less expensive to get the new fridge, hence buying the new fridge is worth it.</em></u>
