Ann has 20$ . She bought 2 notebooks. How much does they costed ?
2x=20
x= 20/2
x=10
So simple interest, you don't compound anything, you will always add 3% from $9500 and it will not change. The equation will look like this:
9500*[1+(0.03*8)]
giving us 9500*1.24 = $11,780
There are 6 numbers on each die.
The total number of out comes is 6 x 6 = 36.
To get a sum of 4, the combinations are: 1 & 3, 2 & 2 or 3 & 1.
To get a sum of 8, the combinations are: 1 & 7, 2 & 6, 3 & 5, 4 & 4, 7 & 1, 6 & 2, 5 & 3
The total of those combinations are: 3 + 7 = 10 total combinations of a sum of either 4 or 8.
The probability of either is 10/36, which can be reduced to 5/18.
step 4: x^2+4=10 |work square x and 2|
step 5: x^2=6 |work subtract 4 from both sides|
step 6: X = 2.44 |work find the root of 6|
When you’re finishing the power of a power, you multiply (ex. (x^2•y^3)^3 will become (x^2)^3 • (y^3)^3 = x^6 • y^9
