Answer:
Javier's equation is not correct because the variable "a" should be multiplied by only and then added to
Step-by-step explanation:
Let
a------>is the tree’s age in years
we have that
-------> Javier's equation
we know that
The equation that represent the situation is equal to
Solve for a
Multiply by both sides
Javier's equation is not correct because the variable "a" should be multiplied by only and then added to

– 5x – 3y = 13: solve for y.
9514 1404 393
Answer:
y = -5/3x -13/3
Step-by-step explanation:
In any "solve for ..." problem, it is useful to start by identifying where the target is and what has been done to it. Here, y is in one term on the left side of the equation and it has had these things done to it:
multiply by -3add -5xWe want to undo these in reverse order. We undo addition by adding the opposite. We undo multiplication by multiplying by the reciprocal (equivalently, dividing). Whatever we do to one side of the equation, we must also do to the other side.
So, first we add the opposite of -5x to both sides of the equation.
-5x +5x -3y = 13 +5x
-3y = 13 +5x . . . . . . . . . collect terms
Next, we undo the multiplication by -3. We can do that by multiplying both sides by 1/(-3) = -1/3.
(-1/3)(-3y) = (-1/3)(13 +5x)
y = -5/3x -13/3 . . . . . also we rearranged the terms to standard form

ABCD is a quadrilateral with AB equal and parallel to DC. prove that AD is equal and parallel to BC
Answer: see below proof
Step-by-step explanation:
Imagine a diagonal line AC
If AB = DC and AB // DC then angle BAC =
Angle ACD Alternate Interior angles theorem.
Then if AB = AD and angle BAC = angle ACD and AC = AC then triangle ABC is congruent to triangle CDA.
If triangle ABC is congruent to triangle CDA then AD = BC because congruent parts of congruent triangles are congruent.
If triangle ABC is congruent to triangle CDA then angle ACB = angle CAD because congruent parts of congruent triangles are congruent.
If angle ACB = angle CAD then AD // BC because of the alternate interior angles theorem.

Step-by-step explanation:
Choose any number, say 20, and divide 729 by 20 ignoring any remainders. " 729/20 = 36 " Find the average of 20 and 36. 20 + 36 / 2 = 28. " Repeat the process until the estimate is the same as the quotient (until the remainder is 0). " 729 / 27 = 27.
Answer:
Answer is solved in the explanation below.
Step-by-step explanation:
Solution:
We have to repeat the process until the estimate is the same as the quotient and remainder = 0. Which can be done only in the case of value = 27 (remainder = 0)
729/27 = 27 (remainder 0)
Let's I am starting this process from 19
So,
729 divided by 19 = 38.3684
Ignoring the remainders
729 divided by 19 = 38
Now, average of 19 and 38 = (19+38)/2 = 28
729 divided by 28 = 26.03
ignoring the remainders = 26
Now, average of 28 and 26 = (28+26)/2= 54/2 = 27
So,
729 divided by 27 = 27
Hence,
estimate is the same as quotient ( and remainder = 0)

Tom bought a pen for $30

20% on his cost price. How much money
did he gain?
Answer:
he gained 6 dollars
Step-by-step explanation:
30 x 0.2
Tom bought a pen for $30 and sold it to gain 20% on his cost price that he gained 6 dollars.
How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
Thus, unit price of something is price of 1 thing.
Lets suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
It is given that Tom bought a pen for $30 and sold it to gain 20% on his cost price.
Therefore,
30 x 20%
30 x 0.2 = 6 dollars
Thus, he gained 6 dollars.
Hence, Tom bought a pen for $30 and sold it to gain 20% on his cost price that he gained 6 dollars.

Answer:
httfjydkyhfkugfufluyfluyflu
Step-by-step explanation:
Answer: [tex]x = 0[/tex]
Step-by-step explanation:
First, we need to get x alone.
To do this we must add -3 + 11. Which will get you 8.
The new equation will now be: [tex]x / 8 = 8[/tex].
Then, we continue to evaluate by subtracting 8 from the area where x is. But as you know, what we do to one side. We must do to the other.
So we subtract 8 from one side, and we subtract 8 from the other.
So the last equation would be.

So, by converse of Pythagoras theorem given side lengths form a right triangle
Answer:
Right
Step-by-step explanation:
The side lengths are 5, 5√3, and 10. This tells me this is a 30° 60° 90° triangle. In a 30° 60° 90° triangle, the relationship between the side lengths are a, a√3, and 2a. a represents the side length of the first leg of the triangle. a√3 represents the second side length, which is the first leg's side length multiplied by √3. Finally, 2a represents the hypotenuse which is two times bigger than the first leg's side length.

Answer:
The copper percentage = 64%
Step-by-step explanation:
Given
Nickle quantity = 9 grams of nickelCopper quantity = 16 grams of nickelTotal quantity = 25 gramsThe percentage of copper metal can be determined using the formula
Copper percentage = [Copper quantity / Total quantity] × 100
= [16 / 25] × 100
= 0.64 × 100
= 64%
Therefore, the copper percentage = 64%
What is the equation for calculating the area of a triangle?
A = 1/4 base · height
B = length · width
C = pi · height
D = 1/2 base · height
Answer:
A= 1/2 base*height
Step-by-step explanation:
: )
The correct equation for calculating the area of a triangle is D = 1/2 base · height.
The equation for calculating the area of a triangle is D = 1/2 base · height. This formula represents the most commonly used method for finding the area of a triangle.
To use this formula, you multiply the base of the triangle by its corresponding height, and then divide the result by 2.
This is because the area of a triangle is equal to half the product of its base and height.
By dividing by 2, we account for the fact that a triangle is essentially half of a parallelogram.
Therefore, the correct equation for calculating the area of a triangle is D = 1/2 base · height.
