X is equal 3. to do this, you do reverse of order of operations. So this means that you would to the 'times 2' first by dividing 4 by 2 to make it 2. then, in the parenthesis, since there is a 'minus 1', therefore you are going to add 1+2 which equals three. <span />
<h2>y = 1x + 2</h2><h2>or</h2><h2>y = x + 2</h2><h2 /><h3>1x is the slope and +2 is the y-intercept</h3>

Answer:
19
Step-by-step explanation:
19 x 2 = 38
Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.
move the decimal point to the right to have 1 real number to the left of the decimal point,
since you are moving it to the right the exponent would be negative
so you get 8.43 x 10^-6
