-2x – 6 = -6x – 2
Answer:
x = 1
Step-by-step explanation:
For this type of equation, you want to combine all like terms. So you can combine the x and the constants. So
-2x - 6 = -6x - 2
+6x +6x
---------------------------
4x - 6 = -2
+6 +6
-----------------
4x = 4

Can more than one triangle be drawn with side
lengths of 4 centimeters and 2 centimeters and
an included angle of 50°? Explain.
Answer: No .
Step-by-step explanation:
If we make two triangles with lengths of 4 centimeters and 2 centimeters and an included angle of 50°, then by SAS congruence postulate both triangle will be congruent.
According to the definition of congruence , if two shapes are congruent then they have equal size and shape.
i.e. they look exactly same.
It means only one triangle is possible with the given measurement .
SAS congruence rule : It says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then we can say that these two triangles are congruent.No, only one triangle can be drawn with side lengths of 4 centimetres, 2 centimetres, and an included angle of 50°.
To determine if more than one triangle can be drawn with given side lengths and an included angle, we can use the Side-Angle-Side (SAS) congruence postulate.
According to this postulate, if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
Given:
One side length is 4 cm (side a).
Another side length is 2 cm (side b).
The included angle between these two sides is 50° (angle C).
Using the Law of Cosines, we can find the length of the third side (side c) of the triangle. The Law of Cosines states that for any triangle with sides a, b, and c, and the angle opposite side c being the following equation holds: [tex]\[ c^2 = a^2 + b^2 - 2ab \cos(\gamma) \][/tex]
Substituting the given values:
[tex]\[ c^2 = 4^2 + 2^2 - 2 \cdot 4 \cdot 2 \cdot \cos(50^\circ) \][/tex]
[tex]\[ c^2 = 16 + 4 - 16 \cdot \cos(50^\circ) \][/tex]
[tex]\[ c^2 \approx 20 - 16 \cdot 0.6428 \][/tex]
[tex]\[ c^2 \approx 20 - 10.2848 \][/tex]
[tex]\[ c^2 \approx 9.7152 \][/tex]
[tex]\[ c \approx \sqrt{9.7152} \][/tex]
[tex]\[ c \approx 3.118 \text{ cm} \][/tex]
Hence, the answer is no; only one triangle can be drawn with side lengths of 4 centimetres, 2 centimeters, and an included angle of 50°.

Mike has $25.00 to rent paddleboards for himself and a friend for 3 hours. Each paddleboard rental costs $3.75 per hour. Use the drop-down menus to complete the statements below about the paddleboard rentals.
Solution:
Given that,
Mike has $25.00 to rent paddleboards for himself and a friend for 3 hours
Each paddleboard rental costs $3.75 per hour
So there are two persons = mike and his friend
1 hour = $ 3.75
Therefore, for 3 hours:
[tex]3 \times 3.75 = 11.25[/tex]
Thus for two person:
11.25 + 11.25 = 22.5
Thus it costs $ 22.5 for mike and his friend to rent paddle board for 3 hours
Remaining amount = 25 - 22.5 = 2.5
Thus Mike has $ 2.5 remaining after rental

A rectangle has dimensions 3x-1 and x+6. Write an expression for the area of the rectangle as a polynomial in standard form
The expression for the area of a rectangle with dimensions (3x-1) and (x+6) is obtained by multiplying these dimensions, resulting in the quadratic expression 3x² + 17x - 6.
Explanation:The dimensions of the rectangle given here are (3x-1) and (x+6). The area of a rectangle can be calculated using the formula length x width. Thus, to obtain an expression for the area of the rectangle, multiply the length (3x-1) by the width (x+6). This results in the expression (3x² - x + 18x - 6). Simplifying this expression, we get 3x² + 17x - 6 as the area of the rectangle in polynomial form, which is a quadratic expression.

#SPJ12
Final answer:
The area of the rectangle with dimensions 3x-1 by x+6 is given by the polynomial 3x² + 17x - 6 in standard form.
Explanation:
To find the expression for the area of the rectangle given the dimensions 3x-1 and x+6, we need to multiply the length by the width. The area A is given by the formula A = length × width, thus:
A = (3x - 1)(x + 6)
Distribute the terms to obtain the polynomial:
A = 3x(x) + 3x(6) - (x) - (6)
Simplify and combine like terms to express in standard form:
A = 3x² + 18x - x - 6
A = 3x² + 17x - 6
Therefore, the expression for the area of the rectangle, written as a polynomial in standard form, is 3x² + 17x - 6.

Find the area of each circle. Use 3.14 forp
12 cm,
The area of the circle is 113.04 cm²
Step-by-step explanation:
The given information are,
The diameter of the circle = 12 cmThe diameter must be converted into radius.Radius = diameter / 2
Radius = 12/2 = 6 cm
Now, the formula for area of the circle is given by πr²
where,
r is the radius of the circle.π has the default value 3.14To calculate the area of circle :
Substitute r=6 and π=3.14,
Area of the circle = (3.14) × (6²)
⇒ 3.14 × 36
⇒ 113.04 cm²
The area of the circle is 113.04 cm²

C. 283.4 in.
B. 62.8 in.
Answer: something is wrong circumference is solved by pi times the diameter or pi times the radius times 2
40 x 3.14 = 125.6
Step-by-step explanation:
Sorry man
Final answer:
The circumference of a circle with a diameter of 40 inches using 3.14 for pi is 125.6 inches, rounded to the nearest tenth.
Explanation:
The student's question is asking for the circumference of a circle with a given diameter using 3.14 for π (Pi). According to the relationship between the diameter and the circumference of a circle, the circumference (C) can be found by multiplying the diameter (d) by π. The formula for the circumference is thus C = πd.
In this case, the diameter is given as 40 inches. Therefore, we calculate the circumference as follows:
C = πdC = 3.14 × 40 inC = 125.6 inSince we are asked to round to the nearest tenth, the circumference of the circle is 125.6 inches.

C. Y = -4x +3
D. Y= -x +8
Answer:
the answer is D
Step-by-step explanation:
x is 7 and y is 1 . just replace the x and y with 7 and 1 , so its 1= -7+8
Answer: y=-x+8
Step-by-step explanation: When 1 is plugged in as x for another equation, y is not equal to 7. However, when you plug 1 in here, you get y equal to 7. Therefore, this is the solution.

A carrot has 5 grams of sugar per serving.
A banana has 15 grams of sugar per serving.
Which statement is true?
CLEAR CHECK
There will always be more sugar in 10 servings of carrots than in a smaller number of servings of bananas.
For an equal number of servings, the bananas will always have 10 more grams of sugar.
For an equal number of servings, the bananas will have three times as much sugar.
The amount of sugar in two servings of carrots is 30 grams.
Answer:
C. For an equal number of servings, the bananas will have three times as much sugar.
Step-by-step explanation:
This is because the amount of sugar will change proportionally with the number of servings, so the ratio of sugar in bananas and in carrots will stay the same as long as the serving size is equal. For example, three servings of bananas would have 45 grams of sugar and 3 servings of carrots would have 15 grams of sugar. If you divide these you will still get a ratio of 1/3, which makes this statement true. Hope this helps! :)

A fire hydrant 2.5 feet high casts a 5 foot shadow. How tall is a street light that casts a 26 foot shadow at the same time?
Here we know the following data:
A fire hydrant 2.5 feet high casts a 5 foot shadow. A street light that casts a 26 foot shadowSo we want to know the height of the street light. Below you have the representation of this problem. We can solve this using proportions because triangles ABC and DEF are similar, so:
[tex]\frac{h}{26}=\frac{2.5}{5} \\ \\ \frac{h}{26}=\frac{1}{2} \\ \\ h=26\times\frac{1}{2} \\ \\ h=13[/tex]
Finally, the height of the street light is 13 ft

2. "The two plans cost the same for 10 movies per month"
3. "The two plans offer the same number of movies for 20$ a month."
What is the plan about?In terms of the above, the graph shows Plan A's line is consistently lower than Plan B's before the equilibrium point. Hence, statement 1 is true.
From the image, one can locate where Plan A and Plan B intersect on the graph at around 10 movies per month, as both plans cost the same. So when you follow the line to the cost axis, Plan A and Plan B have the same monthly cost so statement 2 is true.
