Mathematics
1 answer:
Wittaler [7]2 years ago

Answer:

x = 3.5

y = 8x + 12

Step-by-step explanation:

1) Given the equation

12x = 4(x+2)+20

Expand

12x = 4x+8+20

12x - 4x = 28

8x = 18

x = 28/8

x = 3.5

Hence the value of x is 3.5

2) The standard form of equation in slope intercept form is y = mx+c

m is the slope

c is the y intercept

Get the y-intercept

Substitute m = 8 and (0, 12) into y = mx+c

12 = 8(0)+c

12 = c

c = 12

Get the required equation

Recall that y = mx+c

y = 8x + 12

This gives the required equation

the utility bill for the Millers home was it in April with $132 42% of the bill was for gas and the rest for electricity how muc
Anit [1.1K]
In the given question, there are several data of immense importance. based on these data's the answer to the question can be easily deduced. it is already given that the total utility bill for the month of April in Millers house is $132 and 42% of the bill was paid for gas. remaining amount is paid as electricity charges.
Now
Amount of money paid for gas = 132 * (42/100) dollars
                                                  = 5544/100 dollars
                                                   = 55.44 dollars
Then
The amount of money paid for electricity = (132 - 55.44) dollars
                                                                   = 76.56 dollars
So the Millers paid 55.44 dollars for gas and 76.56 dollars for electricity in the month of April.

Answer:

f(1) = -3 f(n) = 2 f(n - 1) + 1 f(2)

Alternate form:

{f(n) = -f(1)/3, f(n - 1) = f(1)/2 - f(2)/2}

Fill in the blanks in each rule.
Romashka [77]

The ratio of their surface areas will be a²/b². And the ratio of their volumes a³/b³.

<h3>What are the surface area and the volume of an object?</h3>

The size is the amount of space covered by a two-dimensional hard surface.

The volume of an element or compound is the sufficient space it takes up, calculated in cubic units.

1.  The ratio of the surface area of similar solids

If the ratio of the corresponding edge lengths of two similar solids is a:b, then the ratio of their surface areas will be a²/b².

2.  The ratio of the volume of similar solids

If the ratio of the corresponding edge lengths of two similar solids is a:b, then the ratio of their volumes a³/b³.

More about the surface area and the volume link is given below.
