2x−5 = 3 (1−x)+22?
is x=6?

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.

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! :)

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 .

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°.

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.

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.

https://brainly.com/question/15218510

#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.

Radius = diameter / 2

Radius = 12/2 = 6 cm

Now, the formula for area of the circle is given by πr²

where,

To 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

Step-by-step explanation:

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

Answer:-47.5

Step-by-step explanation:

Step 1:Find out how much 12 week of guitar is 15*12=180.

Step 2:Subtract 180 from  132.55 132.55-180+-47.5.

Step 3:Answer -47.5.

The 3 statements that are correct about the graph are:

1. "Plan A offers fewer movies than Plan B for monthly costs greater than 20$"

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."

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.

Answer: 81,250

Step-by-step explanation: find the area. Multiply the length x width. I got 81,250 by multiplying these numbers.

A field that is 250 feet wide and 325 feet long, can be calculated as 81,250 square feet. Since one acre equals 43,560 square feet, this field's size is approximately 1.87 acres.

The question is about converting a field measure in feet into acres. Given that the field is 250 feet wide and 325 feet long, the total area in feet is found by multiplying these two dimensions. Thus, the total area is 250 * 325 = 81,250 square feet.

Now, to convert this into acres, we should know that 1 acre is equal to 43,560 square feet. So, to calculate how many acres is 81,250 square feet, we divide 81,250 by 43,560.

This gives 1.87 acres (rounded to two decimal places). So, this field's size, planted with strawberries, is approximately 1.87 acres.

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:

Since we are asked to round to the nearest tenth, the circumference of the circle is 125.6 inches.
