Answer:
[tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]
Step-by-step explanation:
In this question, we need to simplify [tex]8x-5+2x\dfrac{x}{y}[/tex]
We can convert elements to fractions.
[tex]8x=\dfrac{8xy}{y},\:5=\dfrac{5y}{y}[/tex]
= [tex]\dfrac{8xy}{y}-\dfrac{5y}{y}+\dfrac{2x^2}{y}[/tex]
As the denominators are equal, we can combine the fractions as follows :
=[tex]\dfrac{8xy-5y+2x^2}{y}[/tex]
Hence, the simplified form is : [tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]

What is 10x-2(4x+5)+6
Answer:
2x - 4
Step-by-step explanation:
Expand the brackets.
10x - 2(4x+5) + 6 = 10x - 8x - 10 + 6
Evaluate like terms.
10x - 8x - 10 + 6 = 2x - 4
Answer:
Step-by-step explanation:
10x-2(4x+5)+6 foil
10x-8x-10+6 combine like terms
2x-4
If you need to find x
2x=4 divide by 2
x=2
Jack wanted to make note cards by cutting pieces of paper in half. Before starting he got two more pieces to use. When he was done he had 24 half-pieces of paper. With how many pieces did he start? A) 11 B) 9 C) 8 D) 10
Answer:
D) 10
Step-by-step explanation:
We are told in the question:
Jack wanted to make note cards by cutting pieces of paper in half. . When he was done he had 24 half-pieces of paper.
Step 1
Divide the number of half pieces by 2 to get the number of whole pieces that was cut
= 24 half pieces/2
= 12 full pieces
Step 2
With how many pieces did he start?
We are told in the question that: Before starting he got two more pieces to use
Hence: The number of pieces he started is calculated as:
12 pieces - 2 pieces
= 10 pieces
Hence, he started with 10 pieces

Browning Montana holds the US record for the greatest temperature drop in one day. On January 23, 1916, the temperature changed by an average of -4.17 degrees per hour. To the nearest degree, what was the total temperature change after 24 hours???
Answer:
100°
Step-by-step explanation:
Average temperature change per hour = - 4.17° per hour
Total temperature change after 24 hours
Average temperature change per hour * 24
(-4.17° * 24) = 100.08
Temperature change = 100° (nearest degree)

Answer:
x = 4
Step-by-step explanation:
The parallel segment divides the 2 sides of the triangle proportionally, that is
[tex]\frac{x}{8}[/tex] = [tex]\frac{6}{12}[/tex] ( cross- multiply )
12x = 48 ( divide both sides by 12 )
x = 4
Answer:
Hi
the answer would be:
6/18 = x/x+8 => if you solve the equation, it'll be equal to : x = 4
I hope that it's correct.

Which of the following is a reason that Venus is not ideal for supporting life?
Group of answer choices
It has the perfect amount of atmosphere, but not enough hydrogen.
It has a thin atmosphere which prevents liquid water from existing on the planet surface.
It has a thick atmosphere which causes extremely high temperatures.
It lacks an atmosphere allowing for frequent meteorite collisions.
Answer:
It has a thick atmosphere which causes extremely high temperatures.
Step-by-step explanation:
venus's atmosphere is almost entirely carbon dioxide, and is also about 90x heavier than earth's atmosphere, which is similar to diving 3,000 feet below the ocean.
In conclusion, the answer would be "It has a thick atmosphere which causes extremely high temperatures."

2 × [tex]\frac{1}{2}[/tex] = 1
Step-by-step explanation:
The multiplicative inverse of a number n is [tex]\frac{1}{n}[/tex]
The product of the number and its inverse = - 1
2 and [tex]\frac{1}{2}[/tex] are inverses and
2 × [tex]\frac{1}{2}[/tex] = 1

Step-by-step explanation:
Carl and Derrick are part-time employees. They are paid different hourly rates. One week, Carl worked for 15 hours and Derrick worked for 20 hours. Their combined pay was $640. The next week, Carl worked 20 hours and Derrick worked 25 hours. Their combined pay was $820. What is Carl's hourly pay rate?
Answer:
Carl's hourly pay rate is $16
Step-by-step explanation:
Let x is the hourly rate of Carl and y is the hourly rate of Derrick
∵ Carl's hourly rate is $x
∵ Derrick's hourly rate is $y
∵ Carl worked for 15 hours and Derrick worked for 20 hours
∴ Their combined pay was 15x + 20y
∵ Their combined pay was $640
→ Equate the value of the combined pay
∴ 15x + 20y = 640 ⇒ (1)
∵ The next week, Carl worked 20 hours and Derrick worked 25 hours
∴ Their combined pay was 20x + 25 y
∵ Their combined pay was $820
→ Equate the value of the combined pay
∴ 20x + 25y = 820 ⇒ (2)
Now we have a system of equations to solve it
→ Multiply equation (1) by 5 and equation (2) by -4
∵ 5(15x) + 5(20y) = 5(640)
∴ 75x + 100y = 3200 ⇒ (3)
∵ -4(20x) + -4(25y) = -4(820)
∴ -80x - 100y = -3280 ⇒ (4)
→ Add equations (3) and (4)
∵ (75x + -80x) + (100y + -100y) = (3200 + -3280)
∴ -5x + 0 = -80
∴ -5x = -80
→ Divide both sides by -5 to find x
∴ x = 16
∴ Carl's hourly pay rate is $16

-2x+10y=25
X-25y=3
Elimination method
Answer:
equation form: x=-131/8y -31/40
Step-by-step explanation:
this is addition/elimination
Step-by-step explanation:
(-2x+10y=25) × 2.5
-5x+25y=62.5
x-25y=3
-5x+x+25y-25y=62.5+3
-4x=65.5
x =65.5÷4
=16.375
16.375-25y=3
-25y=3-16.375
-25y=-13.375
y=- 13.375÷-25
=0.535
