What is the missing circle sequence number 40,20,?,40,20,10

Answers

Answer 1

Answer: 40,20,?,40,20,10?
? = 10
Because, the sequence is 40,20,10 and then replay it again

or

40 - 20 = 20
20 - 10 = 10
40 - 20 = 20
20 - 10 = 10

So, ? = 10

Answer 2

Answer: It is 10 that ìs missing because the sequence shows that after 20 is 10

Which explanation best describes how to solve this problem? Gloria was taking photographs at a waterfall. She deleted 18 photographs. Then, during the hike from the waterfall, she took 13 more. She deleted another 9. Now Gloria has 22 photographs left. How many photographs did Gloria have to begin with?

A.Guess and test. Guess that Gloria had 40 photographs to begin with. Subtract the number she deleted (18) and add the number she took (13). Then subtract the second amount she deleted (9). This gives 26. That is 4 more than 22. Add 4 to your guess. Gloria had 44 photographs to begin with.

B.Draw a diagram. Draw a large circle to represent the photographs Gloria had to begin with. Add 22 dots, 18 dots, and 9 dots to the circle. Cross out 13 dots for the ones she took during the hike. Add all remaining dots to figure out that Gloria started with 36 photographs.

C.Translate into an equation. 18 + 13 + 9 – 22 = b
Gloria had 18 photographs to begin with.

D.Work backward. Start with the number of photographs that Gloria has left (22). Add the photographs that were deleted (18 + 9). Then add photographs that she took during the hike (13).
Gloria had 62 photographs to begin with.

15x-7=2+12x I need help with this

Answer:

$\huge{ \boxed{ \bold{ \tt{x = 3}}}}$

♁Question:Solveforx

15x - 7 = 2 + 12x

♁ Step - by - step explanation

$\text{15x - 7 = 2 + 12x}$

Move 12x to L.H.S ( Left Hand Side ) and change it's sign

➛ $\sf{15x - 12x - 7 = 2}$

Move 7 to R.H.S ( Right Hand Side) and change it's sign

➛ $\sf{15x - 12x = 2 + 7}$

Subtract 12x from 15x

Remember that only coefficients of like terms can be added or subtracted.

➛ $\sf{3x = 2 + 7}$

Add the numbers : 2 and 7

➛ $\sf{3x = 9}$

Divide both sides by 3

➛ $\sf{ (3x)/(3) = (9)/(3)}$

➛ $\boxed{ \bold{ \sf{x = 3}}}$

The value of x is $\boxed{ \sf{3}}$

✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄ ✄

☄ Now, let's check whether the value of x is 3 or not!

☥Verification:

$\sf{15x - 7 = 2 + 12x}$

$\dashrightarrow{ \sf{15 * 3 - 7 = 2 + 12 * 3}}$

$\dashrightarrow{ \sf{45 - 7 = 2 + 36}}$

$\dashrightarrow{ \sf{38 = 38}}$

L.H.S = R.H.S ( Hence , the value of x is 3).

✒ Rules for solving an equation :

If an equation contains fractions ,multiply each term by the L.C.M of denominators.
Remove the brackets , if any.
Collect the terms with the variable to the left hand side and constant terms to the right hand side by changing their sign ' + ' into ' - ' and ' - ' into ' + ' .
Simplify and get the single term on each side.
Divide each side by the coefficient of variable and then get the value of variable.

Hope I helped!

Find the distance between points M (6,16) and Z (-1,14) to the nearest tenth, please help step by step

Answers

The distance between 2 points P(a, b) and Q(c,d) is given by the formula:

$\displaystyle{d= √((b-d)^2+(a-c)^2)$ ,

Apply the formula for the points M(6, 16) and Z(-1, 14):

$\displaystyle{d= √((16-14)^2+(6-(-1))^2)= √(2^2+7^2)= √(4+49)= √(53)\approx 7.28$

which rounded to the nearest tenth is 7.3 (units)
