51/2x-7=62
- Multiply both sides by 2x-7
×(2x-7) = 62(2x-7)
2. Switch sides
62(2x-7) = 51
3. Divide each side by 62
=
4. Simplify
2x-7 = 51/62
5. Add 7 on both sides
2x-7+7 = (51/62)+7
6. Simplify
2x = 485/62
7. Divide both sides by 2
2x/2= 485/62/2
x= 485/124
Answer:
solution is
Step-by-step explanation:
f(x)=2|x+6|-4
either x+6 is positive and then |x+6|=x+6
or it is negative and |x+6| = -(x+6)=-x-6
case 1: x>=-6
f(x)= 2x+12-4=2x+8
f(x)=6 <=> 2x+8=6 <=> 2x = 6-8=-2 <=> x = -1
case 2: x<=-6
f(x)=-2x-12-4=-2x-16
f(x)=6 <=> -2x-16=6 <=> 2x=-16-6 = -22 <=> x = -11
so to recap, the solutions are x=-1 and x=-11
The power used in each bolt is 125.
1000- the power together
Divided by the 8 - lights together
So you would do 1000 divided by 8 to get the power of an individual light, which is 125. (1000 ➗ 8 = 125.)
You could even check ur answer by 8 x 125 equals 1000
(3 x 10^6)(8 x 10^-4) = (3 x 8) x 10^(6 - 4) = 24 x 10^2 = 2.4 x 10^3
First of all, rewrite
And divide both sides by 16 to get
The solution is
Which, using the suggested formula, we can compute as
Which evaluates to about - 0.20752..
