Answer:
The student multiplied by 5 instead of dividing by 5
Step-by-step explanation:
At the fourth step, the student multiplied each side by 5 rather than dividing it by 5. The opposite opperation from multiplication is division so they should have divided 5x and 60 by 5 here instead of multiplying it by 5. If this equation was done correctly, the correct answer would be x=12.

Solve for the value of x.
Answer:
[tex]\huge\boxed{\sf x = 37}[/tex]
Step-by-step explanation:
We know that,
The sum of interior angles of a triangle is 180 degrees.
So,
2x + 4 + 2x - 9 + x = 180
5x - 5 = 180
Add 5 to both sides
5x = 180 + 5
5x = 185
Divide both sides by 5
x = 185 / 5
x = 37

6x-3=5x-5
can someone help me
Answer:
x=-2
Step-by-step explanation:
To find the value of x you will have to isolate the x.
6x-3=5x-5 ------> Add 3 to both sides to get rid of the 3
6x=5x-2 ------> Subtract 5x to both sides to get rid of the 5x
1x=-2
1x is the same as x so
x=-2

There are 15 books on a shelf. 8 of these books are new. The rest of them are used.
(a) What is the ratio of used books to all books on the shelf?
(b) What is the ratio of new books to used books?
Answer:
a. 7:15
b. 8:7
Step-by-step explanation:
there are 7 used books and 8 new books, thus, there are 15 books on a shelf.
(a) The ratio of used books to all books on the shelf is [tex]\dfrac{7}{15}[/tex].
(b)The ratio of new books to used books is [tex]\dfrac{8}{7}[/tex].
Given that:
Total number of books = 15
Total number of new books = 8
Total number of used books= 15-8
= 7
(a) The ratio of used books to all books on the shelf is calculated as:
Ratio = [tex]\dfrac{ Used \ books}{ Total \ books}[/tex]
= [tex]\dfrac{7}{15}[/tex]
(b) The ratio of new books to used books is calculated as:
Ratio = [tex]\dfrac{ New \ books}{ Used \ books}[/tex]
= [tex]\dfrac{8}{7}[/tex]
Thus, the ratio of used books to all books on the shelf is [tex]\dfrac{7}{15}[/tex] and the ratio of new books to used books is [tex]\dfrac{8}{7}[/tex].

the length of a rectangle is 5 times as long as its breadth and its area is 1620 m² find area of square whose perimeter is equal to that of a rectangle
Answer:
Area of the square is 2916 [tex]m^{2}[/tex].
Step-by-step explanation:
Let the breadth of the rectangle be represented by w. So that;
length of rectangle = 5w
Area of rectangle = length x breadth
= 5w x w
1620 = 5[tex]w^{2}[/tex]
divide through by 5 to have,
[tex]w^{2}[/tex] = 324
w = [tex]\sqrt{324}[/tex]
= 18
Thus, the breadth of the rectangle is 18 m.
length = 5 w = 5 x 18
= 90 m
The length of the rectangle is 90 m.
Perimeter of the rectangle = 2(l + w)
= 2( 90 + 18)
= 216 m
Perimeter of a square = 4l
where l is the length of its side.
Given that the perimeters of the rectangle and square are equal, then;
4l = 216
l = [tex]\frac{216}{4}[/tex]
= 54
length of the side of square is 54 m.
Therefore,
Area of square = [tex]l^{2}[/tex]
= [tex]54^{2}[/tex]
= 2916
Area of the square whose perimeter is equal to that of the rectangle is 2916 [tex]m^{2}[/tex].

Rearrange the equation
a = 1/2 (b-c)
to make b the subject.
Answer:
b = 2a + c
Step-by-step explanation:
Given
a = [tex]\frac{1}{2}[/tex] (b - c)
Multiply both sides by 2 to clear the fraction
2a = b - c ( add c to both sides )
2a + c = b
After the rearrangement, the equation as b the subject b = 2a + c.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given that the equation;
a = 1/2 ( b - c)
Rearranging the equation;
a = 1/2 ( b - c)
Multiplying 1/2 to the the terms of brackets,
a = (b/2) - (c/2)
b/2 = a + (c/2)
Divide by 2 on both sides of the equation;
b = 2a + c
Therefore, the equation as b the subject b = 2a + c.

4x^2+19-5=0 using quadratic formula
STEP - STEP EXPLANATION:
Trying to factor by splitting the middle term
Factoring 4x2-19x-5
The first term is, 4x2 its coefficient is 4 .
The middle term is, -19x its coefficient is -19 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 4 • -5 = -20
Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is -19 .
-20 + 1 = -19 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -20 and 1
4x2 - 20x + 1x - 5
Step-4 : Add up the first 2 terms, pulling out like factors :
4x • (x-5)
Add up the last 2 terms, pulling out common factors :
1 • (x-5)
Step-5 : Add up the four terms of step 4 :
(4x+1) • (x-5)
Which is the desired factorization

Answer:
1) response b
2) x=35 (response c)
3) response d
Step-by-step explanation:
1) The Pythagorean theorem's "C" value is the value of your hypothenuse, which means that it would be c^2-b^2=a^2
You would set it up as "7^2-4^2", and then to get rid of the squared value, you would have to square root it
2) In this question, you're finding the hypothenuse, therefore the two values given are your "a" and "b" values.
[tex]\sqrt{21^{2} +28^{2} } =x[/tex]
[tex]\sqrt{441+784}=x[/tex]
[tex]\sqrt{1225} =x[/tex]

need some help with geometry
Answer:
Please check the explanation.
Step-by-step explanation:
We know that when two lines intersect we get a pair of opposite angles.
These pair of opposite angles are called vertical angles.According to the vertical angle theorem, if two angles are vertical then the measure of each angle will be the same i.e. the angles will be congruent.
Identifying angle types:
From the figure, it is clear that
The angle (9y+7)° and (2y+98)° are opposite angles.
Hence,
(9y+7)° and (2y+98)° are the vertical angles.Determining the equation
As the vertical angles are congruent, so
(9y+7)° = (2y+98)°
Steps solving the equation
We know the equation of vertical angles (9y+7)° and (2y+98)° such as
(9y+7)° = (2y+98)°
solving for y
9y - 2y = 98 - 7
7y = 91
divide both sides by 7
7y/7 = 91/7
y = 13
Therefore, the value of y = 13

Enter an equation in standard form to model the linear situation.
A bathtub that holds 59 gallons of water contains 14 gallons of water. You begin filling it, and after 5
minutes, the tub is full.
Answer:
In this equation, let "x" equal the rate at which the tub will be filled. The tub holds 32 gallons, which will be one half of the equation. The tub already contains 12 gallons, so this will be half of the other side of the equation. The rate is "x" gallons per minute, and the time it required was 5 minutes, so this would be "5x". Placing all these parts together gives an equation of (32 = 5x + 12) gallons per minute dispensed.
