Answer:
x = -2
Step-by-step explanation:
Arrange 6x + y= -5, -6x + 12y=96 vertically:
6x + y= -5
-6x + 12y=96 Now combine like terms:
--------------------
13y = 91
Solving for y by dividing both sides by 13: y = 7
Find x by substituting 7 for y in the second equation: -6x + 12(7) = 96
Then -6x = -84 + 96, or:
-6x = 12, and so x = -2
What is the value of x in the equation x + 10 = 13?

Hi! Your answer is x = 3.
Please see an explanation for a clear and better understanding to your problem.
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Our goal is to find the value of x. That means what we have to do is to isolate x-term first.
[tex]\huge{x+10=13}[/tex]
To isolate a variable means that to make a variable as a subject or also known as leaving a variable alone. To isolate the x-term for this problem, simply subtract both sides by 10 so we can get rid of 10 from the left side.
[tex]\huge{x+10-10=13-10}\\\huge{x+0=3}\\\huge{x=3}[/tex]
If you are not sure that the answer is correct or not. We can substitute the value of x in the equation.
[tex]\huge{x+10=13}[/tex]
Substitute x = 3 in the equation.
[tex]\huge{3+10=13}\\\huge{13=13}[/tex]
The equation is true for x = 3. Hence, we can conclude that x = 3 is the solution to the equation.

1. a group of friends went to the movies, and the three guys each bought two tickets (t), a popcorn (p) and two drinks (d) for themselves and their dates.
After distributing, we can represent this situation with the expression. __________________.
Answer:
6t + 3p + 6d
Step-by-step explanation:
Given - A group of friends went to the movies, and the three guys each
bought two tickets (t), a popcorn (p) and two drinks (d) for
themselves and their dates.
To find - After distributing, we can represent this situation with the
expression.
Proof -
As given , three guys each bought two tickets (t), a popcorn (p) and two drinks (d) for themselves and their dates.
Let ticket = t
popcorn = p
drink = d ,
Then,
The expression becomes -
3[2t + p + 2d ] = 6t + 3p + 6d
∴ we get
We can represent this situation with the expression - 6t + 3p + 6d
Catherine is adding fractions for her homework. Here is some of the work that Catherine has done. 2/3 + 3/5 = 5/8. In the space below, explain the error that Catherine made when adding.

What is the product of (x+3)(x-3)=7
Answer:
Step-by-step explanation:
What you have here is an equation with two roots. The "product" is (x + 3)(x - 3), which comes out to x^2 - 9.
Thus, you have x^2 - 9 = 7, or x^2 - 16 = 0, and the roots of that are {-4, 4}.

Which statement best explains how the reader can
determine that the narrator is unreliable?
But you should have seen me. You should have seen
how wisely I proceeded—with what caution—with what
foresight—with what dissimulation I went to work! I was
never kinder to the old man than during the whole week
before I killed him. And every night, about midnight, I
turned the latch of his door and opened it-oh so
gently! And then, when I had made an opening
sufficient for my head, I put in a dark lantern, all closed,
closed, that no light shone out, and then I thrust in my
head. Oh, you would have laughed to see how
cunningly I thrust it in!
O The narrator is very kind to the old man during the
whole week before the murder.
O The narrator checks on the old man every night at
midnight to ensure his well-being.
O The narrator closes the lantern tightly so the old
man is not awakened by the bright light.
O The narrator believes that his audience will approve
of and even laugh at his plot to murder the old man.
Answer:
The narrator checks the old man at every night at midnight

Deidre goes out for lunch and realizes that she only has $10 with her. If she wants to leave a 20% tip and knows she will have to pay 5% tax on her lunch, what is the most expensive lunch she can order?
Answer:
$7.60
Step-by-step explanation:
10 decrease 20% =
10 × (1 - 20%) = 10 × (1 - 0.2) = 8
8 decrease 5% =
8 × (1 - 5%) = 8 × (1 - 0.05) = 7.6

The area and length of a rectangle are given below. Find the w, the width.
Answer:
1.5
Step-by-step explanation:
yaaa
This is the same as 1.5 feet and it is equivalent to the improper fraction 3/2.
============================================================
Explanation:
Let's convert the given mixed numbers into improper fractions.
A = 5 & 1/3 = 5 + 1/3 = 15/3 + 1/3 = (15+1)/3 = 16/3
L = 3 & 5/9 = 3 + 5/9 = 27/9 + 5/9 = (27+5)/9 = 32/9
So the area and length are 16/3 and 32/9 respectively.
-------------------
Let's solve for the width W
area = length*width
A = L*W
16/3 = (32/9)*W
9*(16/3) = 9*(32/9)*W ..... multiplying both sides by 9
48 = 32W
32W = 48
32W/32 = 48/32 ....... dividing both sides by 32
W = 48/32
W = (32+16)/32
W = 32/32 + 16/32
W = 1 + 1/2
W = 1 & 1/2 feet is the width
This is equivalent to 3/2 since 48/32 = 3/2
It's also equivalent to 1.5 because 3/2 = 1.5
