2 X { 6 + [ 12 divided ( 3 + 1 ) ] } - 1
3 + 1 = 4
12 divided by 4 is 3
2 X { 6 + [ 3 ] } - 1
6 + 3 = 9
2 X { 9 } - 1
9 X 2 = 18
18 - 1 = 17!
17 is the answer
I used PEMDAS
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
[in order that your supposed to do]
If you look carefully at the grid, you will see that each increment is by 1/8.
That means that for the x-coordinate of P, you can count from -4/8 to get -5/8.
For the y-coordinate, you can count up from 0 to get 3/8.
Then, the answer is (-5/8, 3/8), or the third answer.
3 9/100 would be written as a decimal like this, 3.09. You say three and nine one hundredths. The 9 has to be in the hundredths place, so you put a 0 in front of it. And since the 3 is hole, you put it in front of the decimal point.
3x=x+40
Subtract x from both sides
2x=40
Divide both sides by 2nto get x by itself
x=2
Plug 2 in for x
m∠4 = (3x)
m∠4 = 3(2)
Solve
m∠4 = 6
