Answer: x = 9
Remember: cross-multiply (product of the means equals the product of the extremes) to solve this proportion. It forms a 'cross'-- hence its name.
4 8 4 and 2 are the extremes
------ = ------ 8 and x - 8 are the means
x - 8 2
(4)(2) = 8(x - 8) Simplify
8 = 8(x - 8) Distributive Property
8 = 8x - 64 Add 64 to both sides
72 = 8x Divide by 8 for both sides
9 = x Answer!
x = 9 Answer!
Answer:
9 & 6
Step-by-step explanation:
First, check if, by adding them (sum), they equal 15:
9 + 6 = 15
Next, check the greater number, by multiplying it by 2:
9 x 2 = 18
Check the lesser number, by multiplying it by 3:
6 x 3 = 18
Note that they both have 18 as an answer.
9 & 6 are your answers.

Move the decimal once to the right . Sorry my phone giving problem putting the division to show step by step but I put it in words. 4÷14.4
4×3=12
Put the 3 on top of the 4 where 14.4 is then put the decimal .
Now your answer is 12underneatg 14 then subtract .
You get 2 bring down 4 Now 4 × what equals 24 4×6=24
So put the 6 in top of second 4 where you have 14.4 Your answer is 3.6
Answer:
27.756
Step-by-step explanation:
1) Move all the decimal points to the right and do the multiplication
18 * 1524 = 27756
1.8 to 19 = one move
15.42 to 1542 = two moves
total three decimal point shifts
2) count the number (total) that you moved the decimal points
3) starting from the right move the decimal point that many times to the LEFT in for the answer
27.756
12-0.15×12=$10.2
16-0.15×16=$13.6
20-0.15×20=$17
25-0.15×25=$21.25
Sorry if this didn't help.
