Given equation :−1/2 (x+2) + 112x = 3
We have -1/2 in front of parenthesis on left side .
It's better to remove fraction in an equation, in order make it easier to solve.
In order to remove 2 from denominator of 2, we need to multiply each and every term by 2.
Multiplying each term in the equation by 2, we get
2* −1/2(x+2) +2* 112x = 2*3.
On simplifying this step, we get
-1(x+2) +224x = 6.
Distributing -1 over (x+2), we get
-x -2 +224x = 6
Combining like terms on left side, -x+224x=223x
223x -2 = 6
Adding 2 on both sides, we get
223x -2+2 = 6+2
223x = 8
Dividing both sides by 223, we get
223x/223 = 8/223.
x= 8/223.
Answer: I will help you once you add a graph in the comments of this post
Step-by-step explanation:
Answer:
the answer is 10n-13
Step-by-step explanation:
this is a one step problem, all you need to do is add all the like terms together such as n and 9n and since they are both positives they add up to 10n and then with -10 and -3 they would add together to make -13. thats all there is to it, the answer is 10n-13
Answer: There are 6 bricks in the bag.
Step-by-step explanation:
Convert from mixed number to decimal number. To do it, divide the numerator of the fraction by the denominator and add the result to the whole number part. Then:
Convert from fraction to decimal number. To do it you need to divide the numerator by the denominator. Then, you get:
Let be "x" the number of bricks in the bag<em>.</em>
<em> </em>Based on the information given in the exercise, you can set up the following proportion:
Finally, you must solve for "x" in order to find its value. This is:
Answer:
0.25
Step-by-step explanation:
The only constant in the equation is called the "constant of proportionality." Its value is 0.25.
The constant of proportionality is 0.25.
____
In an equation of the form ...
y = kx
the constant k is called the <em>constant of proportionality</em>. It's a vocabulary (naming) question.
