Solve for x.
16x - 5 = 18x - 2

Answers

Answer 1
Answer: The equation given in the question is
16x - 5 = 18x - 2
16x - 18x = - 2 + 5
-2x = 3
- x = 3/2
- x = 1 1/2
Multiplying both sides of the equation by -1 we get
x = - 1 1/2
So the value of the unknown variable "x" is -1 1/2. I hope there is nothing complicated in the procedure and it is easy for you to understand. In future you can attempt similar kind of problems using this method and will require no additional help from anyone. Only be careful about the calculation part. Other than the calculation part, there is nothing complicated.
Answer 2
Answer: When we have a problem like this, we're trying to get the unknown variable by itself. In this case, it's 'x' and we can use addition, subtraction, multiplication, and division to help us. 

16x - 5 = 18x - 2 

Start by subtracting 16x from both sides: 

16x - 5 -16x = 18x - 2 - 16x 
-5 = 2x - 2 

Now add 2 to both sides: 

-5 + 2 = 2x - 2 + 2 
-3 = 2x 

Now divide both sides by 2 to get x: 

-3 / 2 = 2x / 2 

-3/2 = x 

So x = -3/2 which is the same as x = -1 1/2
seems a little easy but hopes this helps :) :D :)

Of a group of 500 people, 60 are fit enough to climb Mount Shasta in California. The group has 300 women and 200 men. 12% of the men are fit to climb the mountain. What is the probability that a person picked at random from the group is a male or is fit to climb Mount Shasta? A) 59/125 B) 49/100 C) 13/25 D) 56/125

Answers

NO, that answer is wrong it is not13/25

Answer: 0.472 (or in percent near 47.2%).

if you simplify 0.472 and turn it into a fraction you will get  59/125


that is the answer on plato

P(men) or P(fit) = P(men) + P(fit) = 200/500 + 60/500 = 260/500 = 13/25

A student solved this problem by working backwards. Riley has some gerbils. He has 4 times as many as Lukas. Lukas has 2 gerbils. Riley gave 5 away and bought 2 more. How many gerbils does Riley have now?

Students's solution: Lukas has 2 gerbils, so Riley had 2 × 4 to begin with. So Riley had 8 gerbils. He gave away 5, so 8 – 5 = 3. He bought 2, so 2 + 3 = 5. So Riley has 5 gerbils.

Here is another problem that can also be solved by working backwards.

What is the value of x in the equation –x = 4 – 3x + 6?

Answers

remember you can do anything to an equaiton as long as you do it to both sides


-x=4-3x
add 3x both sides
3x-x=4+3x-3x
2x=4+0
2x=4
divide 2
2x/2=4/2
2/2x=2
1x=2
x=2

Answer:

The answer is x=5

Step-by-step explanation:

Bryan’s monthly electric bill is determined by adding a flat administration fee to the product of the number of kilowatt hours of electricity used and the cost per kilowatt hour. When he uses 1,100 kilowatt hours of electricity, his bill is $113. When he uses 1,500 kilowatt hours of electricity, his bill is $153. What is the monthly administration fee?

Answers

We will form the equations for this problem:
(1) 1100*y + z = 113
(2) 1500*y + z = 153
z = ? Monthly administration fee is notated with z, and that is the this problem's question.
Number of kilowatt hours of electricity used are numbers 1100 and 1500 respectively.
Cost per kilowatt hour is notated with y, but its value is not asked in this math problem, but we can calculate it anyway.
The problem becomes two equations with two unknowns, it is a system, and can be solved with method of replacement:
(1) 1100*y + z = 113
(2) 1500*y + z = 153
----------------------------
(1) z = 113 - 1100*y [insert value of z (right side) into (2) equation instead of z]:
(2) 1500*y + (113 - 1100*y) = 153
-------------------------------------------------
(1) z = 113 - 1100*y
(2) 1500*y + 113 - 1100*y = 153
------------------------------------------------
(1) z = 113 - 1100*y
(2) 400*y + 113 = 153
------------------------------------------------
(1) z = 113 - 1100*y
(2) 400*y = 153 - 113
------------------------------------------------
(1) z = 113 - 1100*y
(2) 400*y = 40
------------------------------------------------
(1) z = 113 - 1100*y
(2) y = 40/400
------------------------------------------------
(1) z = 113 - 1100*y
(2) y = 1/10
------------------------------------------------
if we insert the obtained value of y into (1) equation, we get the value of z:
(1) z = 113 - 1100*(1/10)
(1) z = 113 - 110
(1) z = 3 dollars is the monthly fee.
