(x+6)/(x+1)=6/2 Solving proportions

Mathematics
1 answer:
AlexFokin [52]3 years ago
8 0

Answer:

x =  \frac{3}{2}

Step-by-step explanation:

\frac{x  + 6}{x + 1}  =  \frac{6}{2}

\frac{6}{2}  = 3

so, the solution of the equation will be as follows:

\frac{x  + 6}{x + 1}  = 3

3(x+1) = x + 6

3x + 3 = x + 6

3x - x = 6 - 3

x =  \frac{3}{2}

so, the answer will be x = 3/2

FIRST ANSWER GETS BRAINLIEST!!!

I believe it is A and C.

There are 6 slots on the wheel, so both the numbers in A and E can be divided/multiplied to fit this criterion.  For example, 3 times 2 is 6 (the number of gender slots) and 1 times 2 is two, so two out of 6 art teachers will be female.

I hope this helps!!!

Solve the following system of equations using the elimination method. 5x – 5y = 10 6x – 4y = 4
tresset_1 [31]

Answer:

x=-2,y=-4

Step-by-step explanation:

By dividing to lowest terms

5x – 5y = 10= x-y=2.......(1)

6x – 4y = 4=3x-2y=2........(2)

By elimination method

Multiply equation (1) by 3 so as to correspond with equation (2)

3(x-y)=3(2)

3x-3y=6..........(3)

Multiply equation (2) by 1 so as to correspond with equation (1)

1(3x-2y)=1(2)

3x-2y=2..........(4)

Then equation (3)-equation (4)

(3x-3y=6)

-

(3x-2y=2)

__________

-y=4

y=-4

Substitute y=-4 into equation(1)

x-(-4)=2

x+4=2

x=-2

Therefore x=-2,y=-4

Sort the sequence according to whether they are arithmetic gemoentic or neither
vaieri [72.5K]

98.3, 94.1, 89.9, 85.7 (Arithmetic)

1, 0, -1, 0 (Neither)

1.75, 3.5, 7, 14 (Geometric)

-1, 1, -1, 1..... (Geometric)

<h3>Determining the type of a sequence</h3>

An arithmetic sequence has a common difference

A geometric sequence has a common ratio

Considering the given sequences one after the other:

<u>For 98.3, 94.1, 89.9, 85.7,..........</u>

The common difference, d = 94.1 - 98.3 = -4.2

Therefore, 98.3, 94.1, 89.9, 85.7 is an arithmetic sequence

<u>For 1, 0, -1, 0......</u>

The sequence does not have a common difference or a common ratio. Therefore, it is neither an arithmetic nor geometric sequence

<u>For 1.75, 3.5, 7, 14,.....</u>

The common ratio = 3/1.75 = 2

Therefore, it is a geometric sequnec

<u>For -1, 1, -1, 1.....</u>

The common ratio = 1/-1 = -1

It is a geometric sequence
