Answer:
a. x = 13/7
b. j = 3
c. y = 2
d. p = 25
Step-by-step explanation:
Here, it is convenient to combine like terms first. When you do that, you see that one side of the equation has a mix of a constant term and a variable term. Choose the term that matches the kind of term present on the other side of the equation (constant or variable), then add its opposite to both sides. Finally, divide by the coefficient of the variable.
__
a. 3x +13 = 10x . . . . combine like terms
13 = 7x . . . . . . . . . subtract 3x
13/7 = x . . . . . . . . divide by the coefficient of x
__
b. 10j -20 = 10 . . . . combine like terms
10j = 30 . . . . . . . . add 20
j = 3 . . . . . . . . . . . divide by 10
__
c. 6y = 14 -y . . . . . . combine like terms
7y = 14 . . . . . . . . . add y
y = 2 . . . . . . . . . . divide by 7

p = 25 . . . . . . . . . add -8

Comment on solving equations
In these "2-step" equations, the first step (after simplifying, combining like terms) is to "separate the variable and constant terms". The basic idea is to determine what term you don't want where it is, then add its opposite to both sides of the equation.
You can do anything you like to the equation, provided you do the same thing to both sides. When we say "subtract 3x," for example, we mean 3x is subtracted from both sides of the equation. This is an example of the use of the addition property of equality.
The same goes for multiplication or division. You can multiply or divide by anything you like, as long as you do the same thing to both sides of the equation. In the above, "divide by 7," for example, means both sides of the equation are divided by 7.
Solve the equation.
g/4 =3.2
g=?
Answers
g = 12.8
the value of g is 12.8.
To solve the equation g / 4 = 3.2 and find the value of g, we can multiply both sides of the equation by 4 to isolate g.
By multiplying both sides of the equation by 4, we have:
( g / 4 ) * 4 = 3.2 * 4
This simplifies to :
g = 12.8
Therefore, the value of g is 12.8. In the original equation, dividing g by 4 yields a quotient of 3.2, confirming that g = 12.8 is the solution that satisfies the equation g / 4 = 3.2.

Answers
Answer:
So the question is asking you what of the two equations would you chose to solve for the variable. (which means what eqation is easier to solve and why)
Step-by-step explanation:
1) the first one is easier because you could multiple 2 or 5 to get 10 which is a nice number compare to 21 (the other eqaution)
2) the first one bc the second opption you would have a -7y +2 =x and thats a mouth full
3) the first one as well bc I work better with smaller numbers.

x = 7
Step-by-step explanation:
All the angles in a triangle added together equals 180 so:
64 + 71 + 9x - 18 = 180
add like terms
9x + 135 - 18 = 180
9x + 117 = 180
subtract 117 from both sides
9x = 63
divide by 9
x = 7
Answer:
x=7
Step-by-step explanation:
A triangle equals 180 and 64+71 is 135. 180-135 is 45. 9x-18=45.

It cost $2.50 to rent bowling.each game costs $3.25.you have $22. How many games can you bowl
Answers
Answer:
6 games
Step-by-step explanation:
Use the equation 2.5+3.25x=22 to solve in which $2.50 is the initial amount to rent for Bowling, $3.25 the amount of game that is played, $22 for what you have, and x in which is the amount of games you can play at the max. Subtract 2.5 on both sides to get to 3.25x = 19.5. Divide 3.25 on both sides to get your final answer as 6 for your x value in which you can play up to 6 games.
Answer:
6 games
Step-by-step explanation:
you do 2.50 - 22 this you divide 3.25 by what you have left

Does the equation y=x reporestent a function. Explain why
first person to solve gets brailiest
Answers
Answer:
yes because When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x. Equations with exponents can also be functions.
Step-by-step explanation:
The notation y = f(x) defines a function named f. This is read as “ y is a function of x.” The letter x represents the input value, or independent variable. The letter y, or f(x), represents the output value, or dependent variable.

Greetings.
The answer is 7.
Explanation:
- What is Function? -Function is a set of relation with domains that are not repetitive. What I'm trying to say is that in a single set, there cannot be same domain values.
For example,
(1,2) (1,3)
The relation above is not a function since the domain is repetitive (There are two 1's as domain which is not a function.)
But If it is (1,2) (2,1) (3,1) Then It's a function. Because there are no repetitive domains.
The question asks you which value would give the whole set only a relation and not a function.
As explained, 2 repetitive, same domains don't make the relation a function, but rather a relation instead.
Hope this helps! :)
