Solve the simultaneous equations 4x+8y=-4 2y-5x=23

Answer:

x = 49°

Step-by-step explanation:

Angles in a Triangle

The sum of the internal angles in any triangle adds up to 180°.

The figure shows a triangle that includes two angles with the same tick mark. This means they are congruent, i.e. they measure the same.

The larger triangle has three defined angles: 43°, 39°, and 2x. Since the sum of them is 180°:

43° + 39° + 2x = 180°

Operating:

82° + 2x = 180°

Subtracting 82°:

2x = 180° - 82° = 98°

x = 98°/2 = 49°

x = 49°

Answer:

for y=x-1 y=-1 and for y=x2 y=0

Step-by-step explanation:

to find the y intercept substitute x=0 so you have your answer y=-1 and y=0  

Given:

Fabric required for each chair = 10 yards

Fabric required for each sofa = 20 yards.

Total available fabric = 300 yards.

The number of sofas must be at least twice the number of chairs.

Profit on each chair = $50

Profit on each sofa = $80.

To find:

The function that represents the manufacturer's profit, P.

Solution:

Let P represents the manufacturer's profit, x represent the number of chairs and y represent the number of sofas.

Profit on 1 chair = $50

Profit on x chairs = $50x

Profit on 1 sofa = $80

Profit on y sofas = $80y

Total profit = Profit on x chairs + Profit on y sofas

[tex]P=50x+80y[/tex]

Therefore, the required profit function is [tex]P=50x+80y[/tex].

Answer: D. the snail’s path

Step-by-step explanation: because The author uses the most precise words to describe the snail's path.

This excerpt has been taken from Heart of a Samurai, a historical novel written by Margi Preus in 2010. Precise words such as 'shiny', 'ribbon' and 'unfurling' have been used in the second sentence to describe the path of the snail, which is a small animal that has a wet body and moves very slowly. In other words, the author describes the way the path looks by establishing a comparison between the path and a shiny ribbon.

The equation x = 3y + 3w - 1 can be written as in terms of x and y by making the subject w is w = (x - 3y + 1)/3 option (B) is correct.

It is defined as the combination of constants and variables with mathematical operators.

The question is incomplete.

The complete question is:

If x = 3 (y + w) -1 what is the value of w in terms of x and y?

We have an expression:

x = 3 (y + w) -1

To find the value of w in terms of x and y.

By using the distributive property:

x = 3y + 3w - 1

By arranging the equation:

3w = x - 3y + 1

Divide by 3 on both the side:

w = (x - 3y + 1)/3

Thus, the equation x = 3y + 3w - 1 can be written as in terms of x and y by making the subject w is w = (x - 3y + 1)/3 option (B) is correct.

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

17 - (3x + 5) = 3x - 6

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 3 does indeed equal 3.

∴ x = 3 is the solution to the equation.

Answer:

x = 3

Step-by-step explanation:

17 - 1(3x + 5) = 3x - 6

17 − 3 − 5 = 3x − 6

12 - 3x = 3x - 6 subtract five

-3x + 12 = 3x - 6 rearrange terms

-3x = 3x - 18 subtract twelve

-6x = 18 subtract negative three

divide by negative six

Inequality is [tex]15 + p \le 44[/tex]

Choice A) 30 more passengers cannot board the plane. Only 29 more passengers can board the plane

===============================================

Explanation:

15 people are already on the plane.

p is a placeholder for a positive whole number representing the additional number of people that can get on the plane.

In total, the plane holds 15+p individuals.

This expression's largest possible value is 44. Think of it as the ceiling. In terms of math, we call it the maximum. Since at most 44 people can be on the plane, this means the inequality we'll set up is [tex]15+p \le 44[/tex]

This says "15+p is less than or equal to 44". It's the same as saying "15+p is 44 or smaller".

---------------------------

To isolate p, we subtract 15 from both sides

Doing so leads to...

[tex]15+p \le 44\\\\15+p-15 \le 44-15\\\\p \le 29[/tex]

We can see that the largest p can get is 29, meaning that at most 29 more people can board the plane. There's no way that 30 people can board. That unfortunate 30-29 = 1 person must wait for another plane.

This all shows why choice A is the answer.

----------------------------

As a way to check the answer, we can note how p = 29 leads to 15+p = 15+29 = 44. We've filled the plane to full capacity.

If p = 30, then 15+p = 15+30 = 45, and we've gone 1 seat overboard.

Answer:

Step-by-step explanation:

Since both equations equals y, then both equations equal each other.

3x - 1 = 2x + 2

Subtract 2x from both sides

x - 1 = 2

Add 1 to both sides

x = 3

Plug x = 3 into one equation(doesn't matter which)

y = 3x - 1

y = 3(3) - 1

y = 9 - 1

y = 8

Answer:

[tex]x=3[/tex]

[tex]y=8[/tex]

Step-by-step explanation:

From these two equations, we can substitute the first equation into the second equation (or the other way round). This gives us:

[tex]3x-1=2x+2[/tex]

[tex]3x-2x=2+1[/tex] (minus [tex]2x[/tex] and add [tex]1[/tex] on both sides)

[tex]x=3[/tex]

To solve for [tex]y[/tex], we can use substitution again:

[tex]y = 3(3)-1[/tex] (using the first equation given)

[tex]y=8[/tex]

The area of the triangle enclosed by 3 sides of a triangle is 6 cm²

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. To find a triangle's area, use the formula area = 1/2 * base * height.

Given here: The dimensions of a triangle as 6 cm and base 2 cm

We know the area of the triangle is equal to half of the base times height,  

A=1/2×6×2

  =6 cm²

The correct answers are A) Whole number, B) Integer, and C) Rational.

The number √64 is equal to 8. It satisfies the condition √64 = 8 because 8 multiplied by itself (8 x 8) equals 64.

Based on the options provided, the correct answers are:

A) Whole number: Yes, √64 is a whole number. Whole numbers are non-negative integers, and 8 is a non-negative integer.

B) Integer: Yes, √64 is an integer. Integers are numbers that can be positive, negative, or zero without any fractional or decimal parts. In this case, 8 is a positive integer.

C) Rational: Yes, √64 is a rational number. Rational numbers can be expressed as a fraction p/q, where p and q are integers, and q is not zero. The square root of 64 can be written as 8/1, which is a fraction where both the numerator and denominator are integers.

D) Irrational: No, √64 is not an irrational number. Irrational numbers cannot be expressed as fractions and have an infinite non-repeating decimal expansion. However, √64 is a terminating decimal, as it equals 8, which means it is not an irrational number.

Therefore, the correct answers are A) Whole number, B) Integer, and C) Rational.

All the numbers that show 4% as an equivalent fraction, decimal or percent from the listed options are:

Percent counts the number compared to 100.

So, if we have a%, that means for each 100, there are 'a' parts. If we divide each of them with 100, we get:

For each 1, there are a/100 parts.

Thus, 50% = 50/100 = 0.50 (in decimal)

For this case, the percent we have is 4%

That shows that for each 100 items, we have 4 of them. This can be written in fraction as 4/100

Solving this division, we get the result in decimal as 0.04
