Solve the equation 6x+7=8x-15

Mathematics
2 answers:
Andreas93 [3]3 years ago

Answer:

X = 11

Step-by-step explanation:

So, in order to solve this equation, we need to isolate x.

So, we are going to subtract 8x from the right side to get the x on one side. The equation should look like this:

-2x + 7 = -15

Now in order to get x all alone on one side, we need to subtract 7 from the left side.

-2x = -22

Now we just have to divide the -2 from x.

X = 11

Answer:

x = 11

Step-by-step explanation:

6x + 7 = 8x - 15

Step 1: Subtract 8x from both sides.

6x+7−8x=8x−15−8x

−2x+7=−15

Step 2: Subtract 7 from both sides.

−2x+7−7=−15−7

−2x=−22

Step 3: Divide both sides by -2.

-2x/-2 = -22/-2

x = 11

43 5/12 x 11 Please help
zzz [600]
The perimeter is the sum of side lengths. Opposite sides of a rectangle are the same length, so the perimeter is
  P = 11 +43 5/12 +11 +43 5/12
    = 2(11 +43 5/12)
    = 2(54 5/12)
  P = 108 5/6 . . . . feet

The area is the product of length and width. It doesn't matter which of the given dimensions you consider length or width, since you multiply them either way.
  A = 11 * 43 5/12
    = 473 +55/12
  A = 477 7/12 . . . . square feet

Which of the following is most likely the next step in the series
natima [27]

Answer:

C

Step-by-step explanation:

In the pattern, there are some similarities with the first three circles.

1. The number is on the blue half.

2. The halves switch spots, red-blue, blue-red, red-blue.

So, the next one should have the number on the blue half and the next pattern should be red-blue, blue-red, red-blue, and blue-red.

Which one has both the number on the blue half and the pattern blue-red?

C

Given the function, d(t) = 50t, the variable t represents which of the following? Select all that apply. input output function i
Nikitich [7]

Answer:

Input

Independent variable

Step-by-step explanation:

we know that

<u>Independent variables</u>, are the values that can be changed or controlled in a given model or equation

<u>Dependent variables</u>, are the values that result from the independent variables

we have the function

d(t)=50t

In this problem

This is a proportional relationship between the variables d and t

The function d(t) represent the dependent variable or the output

The variable t represent the independent variable or input
