Complete the table to show the steps for combining like terms.

The correct steps are;
7x - 4x + (2 + 1 - 5) (Distributive property)
(2+1 - 5) + (7x - 4x ) (Associative property)
-2 + 3x = 3x - 2 (commutative property)
Given the expression (7-4)x + (2 + 1 - 5)
According to the commutative property A + B = B + A
According to the distributive property A (B+C) = AB + AC
= (7-4)x + (2 + 1 - 5)
= 7x - 4x + (2 + 1 - 5) (Distributive property)
Reordering
= 7x - 4x + (2 + 1- 5)
= (2+1 - 5) + (7x - 4x ) (Associative property)
= -2 + 3x
According to commutative property
-2 + 3x = 3x - 2 (commutative property)

Answer:
(1, 4)
Step-by-step explanation:
as I put in my comments :
in a coordinate grid the x-axis and the x values go left/right, while the y-axis and y values go up/down.
right and up are the corresponding positive sides, left and down the negative ones.
so, moving 8 units to the right means adding 8 to the x value. moving 2 units up adds 2 to the y value.
so, for (-7, 2) the result is (1, 4).
Jessica, Chau, and Kareem sent a total of 84 text messages during the weekend. Kareem sent 4 times as many messages as Chau. Jessica sent 6 fewer messages than Chau. How many messages did they each send?
Answers
Answer:
Number of messages sent by Chau = 15
Number of messages sent by Kareem = 4 * 15 = 60
Number of messages sent by Jessica = 15 - 6 = 9
Step-by-step explanation:
Let number of messages sent by Chau = c
Number of messages sent by Kareem = 4 times as Chau
= 4 * c = 4c
Number of messages sent by Jessica = 6 fewer messages than Chau
= c - 6
Total messages = 84
c + 4c + c - 6 = 84 {Combine like terms}
6c - 6 = 84 {Add 6 to both sides}
6c = 84 + 6
6c = 90 {Divide both sides by 6}
c = 90/6
c = 15
Number of messages sent by Chau = 15
Number of messages sent by Kareem = 4 * 15 = 60
Number of messages sent by Jessica = 15 - 6 = 9
Kareem = 4*15 = 60
Jessica = 15-6 = 9

Step-by-step explanation:
Answer:
x = -3
Step-by-step explanation:

[tex]2x + \frac{5}{8} = 3x - \frac{5}{8}[/tex]
Answers
hi <3
add 5/8 to both sides
2x + 10/8 = 3x
subtract 2x from both sides to get your answer of:
x = 10/8
hope this helps :)
Answer:
[tex]x=\frac{5}{4}[/tex]
Step-by-step explanation:
[tex]2x+\frac{5}{8}=3x-\frac{5}{8}[/tex]
Subtract 5/8 from both sides:-
[tex]2x+\frac{5}{8}-\frac{5}{8}=3x-\frac{5}{8}-\frac{5}{8}[/tex]
[tex]2x+\frac{5}{8}-\frac{5}{8}[/tex]
Add like terms:-
[tex]\frac{5}{8}-\frac{5}{8}=0[/tex][tex]=2x[/tex][tex]3x-\frac{5}{8}-\frac{5}{8}[/tex]
Rule:- [tex]\frac{a}{c} \pm \frac{b}{c}=\frac{a \pm b}{c}[/tex]
[tex]\frac{-5-5}{8}[/tex]Subtract, [tex]-5-5=-10[/tex]
[tex]=\frac{-10}{8}[/tex]Cancel common factor: 2
[tex]=-\frac{5}{4}[/tex][tex]=3x-\frac{5}{4}[/tex]---------------
[tex]2x=3x-\frac{5}{4}[/tex]
Now, subtract 3x from both sides:-
[tex]2x-3x=3x-\frac{5}{4}-3x[/tex]
[tex]-x=-\frac{5}{4}[/tex]
Divide both sides by -1:-
[tex]\frac{-x}{-1}=\frac{-\frac{5}{4}}{-1}[/tex]
[tex]x=\frac{5}{4}[/tex]
