Answer:

The answer is 2.083 repeating.

Step-by-step explanation:

55+65=120

250/120=2.083 repeating.

55*2.083=114.565

65*2.083=135.395

114.565+135.395=249.96

Which I didn't keep all the 3's, so that is why it is 249.96

X-3/2=x+8/6 solve the proportion
Aneli [31]

Answer:

x = 17/2

Step-by-step explanation:

x-3        x+8

------ = ------------

2               6

Using cross products

(x-3) *6 = 2 (x+8)

Distribute

6x - 18 = 2x+16

Subtract 2x from each side

6x-2x-18 = 2x-2x+16

4x-18 = 16

Add 18 to each side

4x-18+18 = 16+18

4x = 34

Divide each side by 4

4x/4 = 34/4

x = 17/2

When Katya factored 288, she listed these factors: 1, 2, 3, 6, 8, 9, 12, 16, 18, 32, 36, 48, 72, 96, and 288. Use a factor rainb
REY [17]

Answer:

Please find a representation of the factor rainbow below.

The missing factors are: 4, 24, and 144

Step-by-step explanation:

The factors of a number are those numbers that can divide another number without remainder. In this case where Katya factored 288, it means she listed the numbers that can divide 288 without reminder (factors of 288). However, among the factors she listed, THREE factors are missing.

To get the missing factors, we can use a FACTOR RAINBOW, which is a display of the factors of a number in a rainbow shape. The factors are arranged from smallest to largest number in such a way that the two numbers attached to a line can be multiplied to give the original number.

From the attached factor rainbow (see attached image), it can be observed that factors:  4, 24, and 144 are missing in the list of factors Katya provided.

We must first Isolate the Variable by removing factors that don't contain the variable: 

2(x + 7) < 12
2x + 14 < 12
2x + 14 - 14 < 12 - 14
2x < -2 
2x / 2 < -2/2
x < -1

Hope this helps!
