Answer:
45
Step-by-step explanation:
Both angles have the same value, therefore, you can set your formula up as
5x-105=2x+30
5x = 2x + 30 + 105
5x - 2x = 135
3x = 135
x = 135/3
x = 45
Answer:
j=38
Step-by-step explanation:
j/-2+7=-12
Subtract 7 from each side
j/-2 +7-7 = -12 -7
j/-2 = -19
Multiply by -2 to isolate j
j/-2 * -2 = -19*-2
j = 38
We want to add something to the right side of the equation to get 81.
x^2 - 18x + 81 = 23
The final step is to factor and subtract 23. (Subtracting 23 is a unnecessary, but whatever)
(x - 9)^2 - 23 = 0
So "x" = 9 + sqrt23
Answer:
You would write it as 3 * 10^6
Step-by-step explanation:
To figure this out, look at the decimal place: you got a huge number. 3,000,000. that's the decimal place, right at the far right side. Move the decimal place until you got a number less than 10, so until the number is 3. How ever many times you had to move the decimal place (in this case six times) is the number you put as the power. So the expression is:
3 * 10^6
