4x-4=4-add four
4x=8-divide by 4
X=2

Answer:

x = 2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

$12x - 4 = (4)(2x) + (4)(1)$
$12x - 4 = 8x + 4$

Step 2: Subtract 8x from both sides.

$12x - 4 - 8x = 8x + 4 - 8x$
$4x - 4 = 4$

Step 3: Add 4 to both sides.

$4x - 4 + 4 = 4 + 4$
$4x = 8$

Step 4: Divide both sides by 4.

$\frac{4x}{4} = \frac{8}{4}$
$x = 2$

CaHeK987 [17]

Answer:

Length ≈ 31cm

Width ≈ 10cm

Step-by-step explanation:

$Let -the-length-be : x\\Let-the-width-be :y\\\\According- to- the- question ; \\x = 3(y)\\x=3y ---------(1)\\2(l+w)=82\\2(x+y)=82\\2x+2y =82 --------(2)\\Substitute- the - given- value- for ; x -in - equation---(1) into -equation (2)\\2(3y)+2y =82\\6y+2y=82\\8y =82\\\frac{8y}{8} =\frac{82}{8} \\y = 10.25\\\\Substitute 10.25 -for ;y -in -eq 1\\x=3y ---------(1)\\x = 3(10.25)\\x = 30.75$

CHECK

$Length =31\\Width = 10\\P = ?\\P= 2(l+w)\\P = 2(31+10)\\P = 2(41)\\P= 82cm$

Help please?????????

Answer:

About 4 times the MAD

Step-by-step explanation:

If you go in from right to left moving you finger one dot at a time then the center of the Data Set A is 42.5 beacuse you add the two numbers together (this is because you have an even number of dots) and the center of Data Set B is 20. The MAD for set A is about 5.83 the MAD for set B is about 5.83 also. Now you have to figure out the means. The mean of data set A is 42.5, the mean for data set B is 20. The difference in the means is 22.5 and if you divide the difference of the means by the MAD you will get 3.859348199, or ≈4 times the MAD

What are the next two numbers in the pattern 2,7,22,67,

Gennadij [26K]

7-2=5

22-7=15

67-22=45

First, we add 20+30 to 67 to find our next number.

67+50=117

Then we add 20+50 to 117 to find the next number.

117+70=187

So the next 2 numbers in the sequence is 117 and 187.

hope it helps!
