Mathematics
1 answer:
julsineya [31]3 years ago
7 0

Answer:

a. Step 1

Step-by-step explanation:

When solving equations, in order to isolate the variable (get the 'x' by itselt), you need to use inverse (opposite) operations.  In the equation:

l2x - 4l - 3 = 3

Step 1: l2x - 4l = -3 + 3 *this step is incorrect because the inverse of subtraction is addition so the '-3' should be added to both sides:

l2x - 4l - 3 + 3 = 3+ 3

Step 2: l2x - 4l = 6

Step 3: 2x - 4 = 6

Step 4: 2x  = 10

Step 5: x = 5

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.

Mekhanik [1.2K]
Answer:
D.20 + 2/10 units

Step-by-step Explanation:
Perimeter is the distance all round a figure.
AB = 10. This is given in the question
AC = √((3-5)²+(4--2)²
= √(4+36)
=√40 = 6.32 units
BC = 5 - -5 = 10 units

Perimeter = AB+AC+BC
= 10+6.32+10
= 26.32 units
From the choices, we do not have an exact answer. The one that mosts suits the perimeter is 20 + units.

Will give brainiest
Mashutka [201]

Answer:

Step-by-step explanation:

We are told that n = 3m + 6.  Substitutte 3m + 6 for n in the second equation, obtaining:

(3m + 6) - 2m = 2, or 3m + 6 - 2m = 2.

Combining like terms yields

m = -4.  

Knowing that m = -4 allows us to calculate n.  Use the first equation, n = 3m + 6, for this purpose:  n = 3(2) + 6 = 12.

Thus, the solution is (2, 12).
