A sofa and a love seat together costs S351. The sofa costs double the love seat. How much does the love seat cost?
Round and write your answer to the tenths place value. Do not include units
Answer:
The love seat cost $117.
Step-by-step explanation:
Given that,
A sofa and a love seat together costs $351.
Let love's seat = x
Sofa's seat = 2x
ATQ,
x+2x = $351
3x = $351

Liliana use for dark power crystals to raise 14 zombie soldiers she wants to know how many zombie soldiers Z she can race with 10 dark power crystals
Answer:
140 zombies
Step-by-step explanation:
Since this is a proportions problem and we are given three values and a variable we must solve for which is the number of zombie soldiers she can raise (z) with 10 dark power crystals. Therefore, we can use the rule of three to solve for this, in which we multiply the diagonal values and divide by the last remaining value in order to solve for the variable like so...
1 crystal <===> 14 zombies
10 crystals <===> Z zombies
(10 * 14) / 1 = 140 zombies

8x^3 − 125y^3/(2x + 5y)3 ÷ 4x^2 + 10xy + 25y^2/4x^2 + 20xy + 25y^2
To divide by a fraction, multiply by its reciprocal.
8x^3 − 125y^3/(2x + 5y)^3 ⋅ 4x^2 + 20xy + 25y^2/4x^2 + 10xy + 25y^2
Simplify the numerator.
Rewrite 8x^3 as (2x)^3.
(2x)^3 − 125y^3/(2x + 5y)^3 ⋅ 4x^2 + 20xy + 25y^2/4x^2 + 10xy + 25y^2
Rewrite 125y^3 as (5y)^3.
(2x)^3 − (5y)^3/(2x + 5y)^3 ⋅ 4x^2 + 20xy + 25y^2/4x^2 + 10xy + 25y^2
Since both terms are perfect cubes, factor using the difference of cubes formula,
a^3 − b^3 = (a − b) (a^2 + ab + b^2) where a = 2x and b = 5y.
(2x − (5y)) ((2x)^2 + 2x (5y) + (5y)^2)/(2x + 5y)^3 ⋅ 4x + 20xy + 25y^2/ 4x^2 + 10xy + 25y^2
Multiply 5 by −1.
(2x − 5y) ((2x)^2 + 2x (5y) + (5y)^2)/(2x + 5y)^3 ⋅ 4x^2 + 20xy + 25y^2/4x^2 + 10xy + 25y^2
Apply the product rule to 2x.
(2x − 5y) (22x^2 + 2x (5y) + (5y)^2)/(2x + 5y)3 ⋅ 4x^2 + 20xy + 25y^2/4x^2 + 10xy + 25y2
Raise 2 to the power of 2.
(2x − 5y) (4x^2 + 2x (5y) + (5y)^2)/(2x + 5y)^3 ⋅ 4x^2 + 20xy + 25y^2/4x^2 + 10xy + 25y^2
Rewrite using the commutative property of multiplication.
(2x − 5y) (4x^2 + 2 ⋅ 5xy + (5y)^2)/(2x + 5y)^3 ⋅ 4x^2 + 20xy + 25y^2/4x^2 + 10xy + 25y^2
Multiply 2 by 5.
(2x − 5y) (4x^2 + 10xy + (5y)^2)/(2x + 5y)^3 ⋅ 4x^2 + 20xy + 25y^2/ 4x^2 + 10xy + 25y^2
Apply the product rule to 5y.
(2x − 5y) (4x^2 + 10xy + 52y^2)/(2x + 5y)^3 ⋅ 4x^2 + 20xy + 25y^2/4x^2 + 10xy + 25y^2
Raise 5 to the power of 2.
(2x − 5y) (4x^2 + 10xy + 25y^2)/(2x + 5y)^3 ⋅ 4x^2 + 20xy + 25y^2/4x^2 + 10xy + 25y^2
Cancel the common factor of 4x^2 + 10xy + 25y^2.
((2x − 5y)/(2x + 5y)^3) (4x^2 + 20xy + 25y^2)
Multiply
(2x − 5y) (4x^2 + 20xy + 25y^2)/ (2x + 5y)^3
Factor using the perfect square rule.
Rewrite 4x^2 as (2x)^2.
(2x − 5y) ((2x)^2 + 20xy + 25y^2)/ (2x + 5y)^3
Rewrite 25y^2 as (5y)^2.
(2x − 5y) ((2x)^2 + 20xy + (5y)^2)/ (2x + 5y)^3
Check that the middle term is two times the product of the numbers being squared in the first
term and third term.
20xy = 2 ⋅ (2x) ⋅ (5y)
Rewrite the polynomial.
(2x − 5y) ((2x)2 + 2 ⋅ (2x) ⋅ (5y) + (5y)2)/(2x + 5y)^3
Factor using the perfect square trinomial rule a^2 + 2ab + b^2 = (a + b)^2, where a = 2x and b = 5y.
(2x − 5y) (2x + 5y)^2/ (2x + 5y)^3
Cancel the common factor of (2x + 5y)^2 and (2x + 5y)^3.
Factor (2x + 5y)^2 out of (2x − 5y) (2x + 5y)^2.
(2x + 5y)^2 (2x − 5y) / (2x + 5y)^3
Cancel the common factors.
2x − 5y / 2x + 5y
Answer:
This may be wrong but: (2x - 5y) ((2x)^2 + 10xy + (5y)^2) over (2x + 5y) (4x^2 + 10xy + 25y^2)
Step-by-step explanation:
Solve the system of linear equations by elimination,
-y - 10 = 6x
5x +y = -10
Hey again!
The solution to the given system is (0, -10)
To solve using elimination, we have to add the equations together, and the "y"s will cancel out, and then solve the equations:
5x - 10 = 6x - 10
Now solve.
Add "10" to both sides:
5x = 6x
Subtract "5x" from both sides
0 = x
Now, we plug in the solved "x" value in an equation to solve for "y".
5(0) + y = -10
y = -10
We now know that the solution to the given system is (0, -10)
Hope this helps! Have an amazing day, and remember, you've got this!!
The solution to the given system of linear equations is (0, -10) which is determined by the elimination method.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The system of linear equations is given in the question:
-y - 10 = 6x ....(i)
5x +y = -10 ....(ii)
To solve using elimination, we have to add the equations (i) and (ii) together, and the "y" will be eliminated, and then solve the equations:
⇒ 5x - 10 = 6x - 10
Add "10" to both sides of the above equation
⇒ 5x = 6x
Subtract "5x" from both sides
⇒ 0 = x
⇒ x = 0
Now, substitute the value of x = 0 in equation (ii) to solve for "y".
⇒ 5(0) + y = -10
⇒ y = -10
Therefore, the solution to the given system of linear equations is (0, -10).

Sophie had two different coupons for the book store, 15% off coupon or the $2.50 off coupon. The store only allows you to use one coupon at time. The book she wanted was $12. Which is a better coupon for sophie to use and why
Answer:
$2.50 coupon is better as it gives a cheaper sale price.
Step-by-step explanation:
Price of good = $12
Sale price = price of good - coupon
Coupon 1 :
$2.50
Sale price = $12 - $2.50 = 9.50
Coupon 2:
15% off
Sale price =. (100 - 15)% * 12
= 0.85 * 12
= $10.2

Answer:
Parallel
Step-by-step explanation:
2x + 3y = 15
3y = -2x + 15
y = -2/3x + 5 (slope = -2/3)
4x + 6y = -48
6y = -4x - 48
y = -2/3x - 8 (slope = -2/3)
Since the slopes are the same, they are parallel.
Step-by-step explanation:
Hey there!
Given equations are;
2x+3y = 15...............(i)
4x+6y = -48…………(ii)
From eqaution (i)
2x+3y = 15
Slope (m1) = (-coefficient of x)/(coefficient of y)
Slope (m2) = (-2)/(3)
Therefore, slope (m1) = -2/3.
From eqaution (ii).
4x+6y= -48
Slope (m1) = (-coefficient of x)/(coefficient of y)
Slope (m2) = (-4)/6
Therefore, slope (m2) = -2/3.
Now;
Condition of parallel lines: m1=m2
-2/3 = -2/3
So, they are parallel.
