Answer:
c = 4
Step-by-step explanation:
x + 5x = 12/5
30x = 12
[tex]x_{1}[/tex] = 2/5
[tex]x_{2}[/tex] = 2
c = [(2/5)*2] * 5 = 4
(5x - 2)(x - 2) = 0
5x² - 12x + 4 = 0
Is BAK ~ JOL? Explain your reasoning.
Answer:
Since the ratios are not equal the triangles are not similar
Step-by-step explanation:
Triangle Similarity
For both triangles to be similar, their corresponding side lengths should be proportional by the same scale factor.
Triangle BAK has side lengths: BA=60, AK=38, and KB=36
Triangle JOL has side lengths: JO=50, OL=28, and LJ=26.
Calculating the ratios of the corresponding side lengths:
BA/JO=60/50=1.2
AK/OL=38/28=1.36
KB/LJ=36/26=1.38
Since the ratios are not equal the triangles are not similar

Manoj and Tamar are arguing about a number trick they heard.
Tamar tells Andrew to think of a number, multiply it by five and
subtract three from the result. Then Manoj tells Andrew to think
of a number, add five and multiply the result by three. Andrew
says that whichever way he does the trick he gets the same
answer.
a. What was the number Andrew started with?
b. What was the result Andrew got both times?
c. Name another set of steps that would have resulted in the
same answer if Andrew started with the same nu
Answer:
a . Andrew's started with number 9
b. 42
c. 4x + 6 = (x+12)*2
Step-by-step explanation:
Let the Andrew's number is x
Tamar tells Andrew to think of a number, multiply it by five andsubtract three from the result
5x - 3
Manoj tells Andrew to think of a number, add five and multiply the result by three.(x +5)*3
as he was getting the same answer so both the numbers will be equal
5x -3 = (x+5)*3
5x - 3 = 3x + 15
2x = 18
x = 9
a. Andrew's started with number 9
b. (1) 5x- 3 = 5*9 - 3
= 42
(2) (x + 5)*3
= 14*3 = 42
c. Think of a number, then multiply it with 4 then add 6 in it
Think of a number add 12 in it then then double it.
4x + 6 = (x+12)*2
x = 9

Step-by-step explanation:
10 2.5 16 4 ? 7.5 48 12 Which statement explains how to find the number of minutes it takes to bike 7.5 miles? Find the ratio of minutes to miles, 4:1. Divide 7.5 by 4. Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4. Find the difference between 16 and 10. Add the difference to 16. Find the difference between 16 and 10. Add the difference to 7.5.
Answer:
Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.
Step-by-step explanation:
Given
Minutes: 10 || 16 || ? || 48
-----Miles: 2.5 || 4 || 7.5 || 12
Required
Which statements solve for the missing value?
First, we need to calculate the ratio of minutes to mile
[tex]Ratio = \frac{Minutes}{Mile}[/tex]
When minutes = 16; mile = 4
So, we have:
[tex]Ratio = \frac{16}{4}[/tex]
[tex]Ratio = 4[/tex]
Next, we multiply the ratio by 7.5
[tex]Minutes = Ratio * 7.5[/tex]
[tex]Minutes =4 * 7.5[/tex]
[tex]Minutes = 30[/tex]
Hence, option B answers the question.

A(X)=X^2-10x+25-(x-5)(2x+3)
Answer:
the ans is -x^2-3x+40........
Answer:
(5 - x )(8 + x)
Step-by-step explanation:
A(x) = x² - 10x + 25 - (x - 5)(2x + 3)
x² - 10x + 25 = (x - 5)²
A(x) = (x - 5)² - (x - 5)(2x + 3) =
(x - 5)(x - 5 - 2x - 3) =
(x - 5)(- x - 8) =
(5 - x )(8 + x)
A is at (-2, 1) and B is at (4, -1).
P is a point on y-axis which is equidistant from A and B.
What are the coordinates of P?
Answer:
The coordinates of P are (1,0)
Step-by-step explanation:
Midpoint
The midpoint (xm,ym) of a segment defined by points (x1,y1) and (x2,y2) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
We need to find the coordinates of P which is equidistant from the endpoints A=(-2,1) and B=(4,-1).
Calculate the midpoint:
[tex]\displaystyle x_m=\frac{-2+4}{2}=1[/tex]
[tex]\displaystyle y_m=\frac{1-1}{2}=0[/tex]
Thus, the coordinates of P are (1,0)
Note the midpoint does not lie on the y-axis but on the x-axis.

Para hacer una ración de puré de papa se necesita 1/5 de kg. ¿Cuántas raciones se pueden hacer con 7/4 de kg?
Gracias
Answer:
Cantidad de raciones= 8.75 raciones
Step-by-step explanation:
Dada la siguiente información:
Para hacer una ración de puré de papa se necesita 1/5 de kg.
Vamos a pasar las cantidades a décimales:
Ración puré= 0.2kg
Kg de papa= 7/4= 1.75 kg
Ahora, dividimos la cantidad total por la cantidad unitaria:
Cantidad de raciones= 1.75/0.2
Cantidad de raciones= 8.75 raciones

Carmen is designing an intersection of the rail line and four streets. She wants to know which streets are parallel. Transversal t crosses lines c, d, e, f forming 16 angles. Clockwise from top left, the angles formed with line c are blank, blank, blank, 114 degrees; with line d are blank, blank, 68 degrees, blank; with line e are blank, 112 degrees, blank, blank; with line f are blank, blank, 66 degrees, blank. Which streets are parallel? Check all that apply. c || d c || e c || f d || e d || f e || f
Answer:
The answer is "c || f and d || e".
Step-by-step explanation:
Its acute collision angle between e and t is:
[tex]\to 180^{\circ}- 112^{\circ} = 68^{\circ}[/tex]
Its angle refers to the acute corner of d, so d and e are parallel to its extreme angle of crossroads between c and t is:
[tex]\to 180^{\circ} -114^{\circ} = 66^{\circ}[/tex]
Its angle is identical to the acute angle of, f so, that c and f are parallel. [tex]d | |e, c || f[/tex]
All "corresponding" to extreme angles at crossings of t. Thus the associated points are connected to their congruence.

9 t-shirts and a hat costs £93.00
4 t-shirts and a hat costs £43.00.
How much does a t-shirt cost?
How much does a hat cost?
Answer:
A t-shirt costs 10.00 pounds and a hat costs 3.00 pounds.
Step-by-step explanation:
x is a t-shirt
y is a hat
9x + y = 93.00
4x + y = 43.00
(9x + y) - (4x + y) = 93.00 - 43.00
9x + y - 4x - y = 50.00
5x = 50.00
x = 50.00/5
x = 10.00 [a t-shirt costs 10.00]
4x + y = 43.00
4×10.00 + y = 43.00
40.00 + y = 43.00
y = 43.00 - 40.00
y = 3.00 [a hat costs 3.00]

What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Yousef typed a 36-word paragraph in 2/3 minutes. Therefore, the typing speed of Yousef in a minute is,
Typing speed of Yousef = 36 words/ (2/3) minutes
= (36×3)/2 words per minute
= 54 words per minute
Hence, the typing speed of Yousef in a minute is 54 words per minute.

1. Laura earns $115 a month babysitting. If she saves all of the
money she earns in June and July and uses it to buy a bicycle

A. $230,00
B. $43.00
C. $60.00
D. $72.00
A
B
OC
Answer:
Laura will have exactly $72.00 after purchasing the bicycle.
Step-by-step explanation:
We are given that Laura ends $115 per month of babysitting.
We also learn that she wants to save her money from June and July, which means she wants to save her money over a period of two months.
Therefore, she will earn $115 twice.
[tex]\displaystyle{\$115 \times 2 = \$230}[/tex]
Then, she wants to purchase a bicycle that costs $158, so we need to subtract the cost of the bicycle from her total earnings.
[tex]\$230 - \$158 = \$72[/tex]
Therefore, Laura will have exactly $72.00 remaining after her purchase.
