To obtain 490 using the number 7 four times, you can use multiplication and addition. One way to achieve this is by calculating (7 \times 7 \times 10 = 490). Here, you can represent 10 as (7 + 3), so the operation can be expressed as (7 \times 7 \times (7 + 3) = 490).
Let the number be represented as ( x ). According to the problem, four times the number plus eight times the number can be written as ( 4x + 8x = 36 ). This simplifies to ( 12x = 36 ). Dividing both sides by 12 gives ( x = 3 ). Thus, the number is 3.
If: 4x-6 = 6x then x = -3
You can create numbers 10-20 using four 3s through various mathematical operations. For example, to make 10, you can use the expression (3 \times 3 + 3 - 3). To create 12, you can use (3 \times 3 + 3). Similarly, for 15, you can use (3 \times 3 + 3 + 3), and for 18, the expression (3 \times 3 + 3 + 3 + 3) works as well.
The number is 3

3³ ÷ 3 x 3 = 27
3*3 + 3/3 = 10

There are 3 possible outcomes for each spin of the spinner. To find the total number of possible outcomes after spinning it four times, you would multiply the number of outcomes for each spin (3) by itself four times (3^4), resulting in 81 possible outcomes.
Let the number be represented as ( x ). According to the problem, four times the number plus eight times the number can be written as ( 4x + 8x = 36 ). This simplifies to ( 12x = 36 ). Dividing both sides by 12 gives ( x = 3 ). Thus, the number is 3.
4(N-3) is the formula, do the math from there and you get "N-3"
