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.

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

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

An artist builds a sculpture out of metal and wood that weighs 14.4 kilograms. 3/4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh?
Answers
Answer: weight of wood part = 3.6 kilogram.
Step-by-step explanation:
Sculpture made of both metal and wood = 14.4 kilogram
Weight of metal=3/4 of 14.4 kilogram
which means the weight of metal = 3/4 x 14.4kg= 10.8kg
Since the rest is wood, we can say that
weight of wood = Total weight - weight of metal
= 14.4 kilogram- 10.8 kilogram= 3.6 kilogram
