Step-by-step explanation:
y = 4x - 1
2x + 2y = 3
2x + 2(4x - 1) = 3
2x + 8x - 2 = 3
10x = 3 + 2
x = 5/10
x = 1/2
y = 4x - 1
y = 4(1/2) - 1
y = 2 - 1
y = 1
(x,y) = (1/2 , 1)

4. Which of the following equation represent quadratic?
A. The cost of each pen is Php 8.50. How many pens can be bought by Php 850?
B. The length of a field is 2 m more than twice its width and its area is 24 m2.
C. The length of the rectangular room is 3 more than the width and its area is at least 56m2.
D. The length of a wall is 8 m more than its width. If the area of the wall is less than 40 m2.
5. What are the dimensions of the largest rectangular field that can be enclosed with 100 m of wire?
A. 24 m x 26 m
B. 25 m x 25 m
C. 50 m x 50 m
D. 50 m x 25 m
Answer:
Step-by-step explanation:
4) B , C and D represents the quadratic equation.
B) width = w
length = l = 2w + 2
Area = 24 square m
l *w = 24
(2w + 2)*w = 24
2w*w + 2w = 24
2w² + 2w - 24 = 0
Divide the entire equation by 2
w² + w - 12 = 0
C) width = w
Length = w + 3
Area = 40 m²
(w + 3 ) *w = 56
w*w + 3*w = 56
w² + 3w - 56 = 0
D) Width = w
Length = w + 8
Area = 40
(w + 8)*w = 40
w² - 8w - 40 = 0
5) B) 25 * 25
25 *25 gives the largest area that has its perimeter 100

The measure of the second angle of a triangle is twice the measure of the first. The measure of the third angle is six times the measure of the first. Find the measure of the third angle
Answer:
120°
Step-by-step explanation:
The sum of all angle measurements for the interior of the angle is 180°.
Let the first angle measurement be denoted as "x".
The second angle measurement is twice that of the first, or "2x".
The third angle measurement is six times of that of the first, or "6x".
Set the equation:
x + 2x + 6x = 180
Simplify. Combine like terms. Like terms are terms with the same, as well as same amount of said variable:
(x + 2x + 6x) = 180
(9x) = 180
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 9 from both sides of the equation:
(9x)/9 = (180)/9
x = 180/9 = 20
x = 20
Next, plug in 20 for x for the third measurement:
6x = 6 * (20) = 120°
120° is your answer.

Find the values of x and y that make the quadrilateral a parallelogram. (4x + 13) (4y + 7)º (3x - 8) (5x - 12)
The sum of angles in a parallelogram adds up to 360 degrees
The values of x and y are 25 and 15, respectively.
The angles are given as:
[tex]\mathbf{\angle 1 = 4x + 13}[/tex]
[tex]\mathbf{\angle 2 = 4y + 7}[/tex]
[tex]\mathbf{\angle 3 = 3x - 8}[/tex]
[tex]\mathbf{\angle 4= 5x - 12}[/tex]
The opposite angles of a parallelogram are equal.
So, we have:
[tex]\mathbf{4x + 13 = 5x - 12}[/tex]
Collect like terms
[tex]\mathbf{5x - 4x = 13 + 12}[/tex]
[tex]\mathbf{x = 25}[/tex]
Simiarly, we have:
[tex]\mathbf{4y + 7 = 3x -8}[/tex]
Substitute 25 for x
[tex]\mathbf{4y + 7 = 3 \times 25 -8}[/tex]
[tex]\mathbf{4y + 7 = 75 -8}[/tex]
[tex]\mathbf{4y + 7 = 67}[/tex]
Subtract 7 to both sides
[tex]\mathbf{4y = 60}[/tex]
Divide both sides by 4
[tex]\mathbf{y = 15}[/tex]
Hence, the values of x and y are 25 and 15, respectively.

A game lasts 5/8 hours. Jane played 4 of these games.
For how long did she play in total?
Answer: 2 hours 30 minutes in total.
Step-by-step explanation: Because when it says that a game lasts for 5/8 hours and Jane only play 4 of these games, Which means that you have to multiply the number of hours lasted by the total number of games that have been played. Therfore 5/8 x 4 = 20/8 but you simplify your answer and you will get 2 hours and 30 minutes in total.

Step-by-step explanation:
Find common denominator
[tex]\frac{d}{3} +\frac{3*9.9}{12.9}[/tex]
Combine fractions with common denominator
[tex]\frac{d+3*9.9}{3} =12.9[/tex]
Multiply the numbers
[tex]\frac{d+29.7}{3} =12.9[/tex]
Multiply all terms by the same value to eliminate fraction denominators
[tex]3(\frac{x+29.7}{3} )=3 * 12.9[/tex]
Cancel multiplied terms that are in the denominator
x=29.7= 3 · 12.9
Multiply the number
x= 12.9=38.9
Subtract 297 from both sides of the equation
x+29.7-29.7=38.9-29.7
Simplify
x = 9.0
Hence, the answer is 9.

[tex]s = \frac{w - 10e}{m} [/tex]
I'm trying to solve for w
9514 1404 393
Answer:
w = ms +10e
Step-by-step explanation:
The basic idea is to undo what is done to w. Here, 10e is subtracted, and the difference is divided by m. We undo these in reverse order. To undo the division, we multiply by m. To undo the subtraction, we add the quantity that was subtracted. Any operation that we perform must be done to both sides of the equation.
[tex]s = \dfrac{w - 10e}{m}\qquad\text{given}\\\\ms=w-10e\qquad\text{multiply by $m$}\\\\ms+10e=w\qquad\text{add $10e$}[/tex]
Usually, you want to write that with w on the left:
w = ms +10e
