Which of these strategies would eliminate a variable in the system of equations?
10x + 4y = -2
5x - 2y = 2
If NML ~ SRL find the value of x.
Answer:
x = 5
Step-by-step explanation:
Since the triangles are similar, corrresponding sides are in proportion.
[tex]\frac{NM}{SR} = \frac{ML}{RL} = \frac{NL}{SL}[/tex]
Using the equation formed by the second and third fraction above we get
[tex]\frac{28}{24} = \frac{3x - 1}{x + 7}[/tex]
28(x + 7) = 24(3x - 1)
28x + 196 = 72x - 24
44x = 220
x = 5

In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet. Find the measure of ∠H to the nearest tenth of a degree.
Answer:
21.9°
Step-by-step explanation:
In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet. Find the measure of ∠H to the nearest tenth of a degree.
We solve this above question using the Sine rule
a/sin A = b/sin B
In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet.
Hence:
HI/∠J = JH/∠H
= 8/sin 90° = 1.9/sin ∠H
Cross Multiply
∠H = arc sin(sin 1.9 × 90/8)
∠H = 21.9°
Kent can paint a room in twice as fast as Luannda. Together they can paint the room in 5 hours. How long would it take Kent to paint the room alone? Write an equation to solve
Answer:
for kent it would be [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
The computation is shown below:
Let us assume Luannda be [tex]\frac{x}{1}[/tex]
And for kent be 2x
Together they take 5 hours
So
[tex]\frac{x}{1} + \frac{2x}{1} = 5\ hours\\\\3x = 5\\\\x = \frac{5}{3}[/tex]
So for kent it would be [tex]\frac{1}{5}[/tex]

Maggie goes to two different stores to shop for t-shirts. Both stores are having a sale.
At Store A, t-shirts are regularly priced at $22 but are on sale for 25% off.
At Store B, t-shirts are regularly priced at $30 but are on sale for 45% off.
Which of the following is true about the sale price of a t-shirt at the two stores?
A. Store B has the better price because 45% is greater than 25%.
B. Store A has the better price because $22 is less than $30.
C. The sale price is the same for both stores.
D. The sale price cannot be determined.

Which expression has the same value as 8 – (-1)?
Answer: 9
Step-by-step explanation:
Two negatives make a positive. So the expression 8-(-1) is equal to 9, because the two subtraction signs the equation create an addition sign, and the equation becomes 8 + 1.
Therefore, 9 has the same value as 8-(-1).

Tammy has a rectangular rug with an area of 21 square feet. The rug is 4 feet longer than it is wide. Which equation can be used to determine the length and the width of the rug?
A.
21 = 4w^2
B.
21 = w^2 + 4w
C.
21 = w^2 – 4w
D.
21 = w^2 + 4
Answer:
D
Step-by-step explanation:
The equation to determine the length and width of the rug is 21 = w² + 4w.
What is Rectangle?A rectangle is a four sided figure with opposite sides are equal .
Area of a rectangle = Length x width
Given that A rectangular rug with an area of 21 square feet.
The rug is 4 feet longer than it is wide.
Let 'l " be the length of the rug and 'w' be the width of the rug
Length is 4 feet longer than its width
l = w + 4
Area is 21 square feet.
Area = l x w
21 = (w + 4)w
21 = w² + 4w
The equation to determine the length and width of the rug is 21 = w² + 4w.
So width is 3 ft
Length = w +4
length = 3+4= 7 feet
Thus Length of the rug is 7 feet
Length of rug = 7 feet
width of the rug = 4 feet

Which of the following equations are equations of a direct variation? Choose all that apply.
(a) x=−2y
(b) x+2y=12
(c) 3x−2y=0
(d) 5x^2+y=0
(e) y =0.3x +1.6
(f) y−2=x
Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x This is equivalent to multiplying x by -1/2, so this is an example of direct variation.(b) x + 2y = 12
2y = 12 - x y = 6 - 1/2x This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.(c) 3x - 2y = 0
-2y = -3x y = 3/2x This follows the format of y = kx, so it is an example of direct variation.(d) 5x² + y = 0
y = -5x²This is not in the form of y = kx, so it is NOT an example of direct variation.(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.(f) y - 2 = x
y = x + 2 2 is being added to x, so it is NOT an example of direct variation.The following equations are examples of direct variation:
x = -2y 3x - 2y = 0Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x
This is equivalent to multiplying x by -1/2, so this is an example of direct variation.
(b) x + 2y = 12
2y = 12 - x
y = 6 - 1/2x
This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.
(c) 3x - 2y = 0
-2y = -3x
y = 3/2x
This follows the format of y = kx, so it is an example of direct variation.
(d) 5x² + y = 0
y = -5x²
This is not in the form of y = kx, so it is NOT an example of direct variation.
(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.
(f) y - 2 = x
y = x + 2
2 is being added to x, so it is NOT an example of direct variation.
The following equations are examples of direct variation:
x = -2y
3x - 2y = 0
