Given that 6 x − 4 y = 29 Find x when y = 4

Answers

Answer 1

Answer:

[tex]x=15/2=7.5[/tex]

Step-by-step explanation:

So we have the equation:

[tex]6x-4y=29[/tex]

And we want to find x when y is 4.

So, substitute y for 4:

[tex]6x-4(4)=29[/tex]

Multiply:

[tex]6x-16=29[/tex]

Add 16 to both sides:

[tex]6x=45[/tex]

Divide both sides by 6:

[tex]x=45/6[/tex]

Reduce by dividing both layers by 3:

[tex]x=15/2=7.5[/tex]

And this is our answer :)

Answer 2

Answer:

[tex]7.5 \: or \:7\frac{1}{2}[/tex]

Step-by-step explanation:

[tex]6x- 4 y = 29\\x =?\\y =4[/tex]

Substitute 4 for y in the given equation ;

[tex]6x-4(4)=29\\6x -16=29[/tex]

Collect like terms

[tex]6x = 29+16[/tex]

Simplify

[tex]6x = 45[/tex]

Divide both sides of the equation by 6

[tex]\frac{6x}{6} = \frac{45}{6} \\\\x =\frac{15}{2} \:or \: 7.5 \: or \:7\frac{1}{2}[/tex]

Setting 7/3 equal to which ratio would result in a valid proportion?
9/49
18/42
42/18
49/9

Answers

the answer is 42/18 because if you were to multiply each number by 6 you will get 42/18

To determine which ratio would result in a valid proportion when set equal to StartFraction 7 over 3 EndFraction, we need to find the ratio that is equivalent to StartFraction 7 over 3 EndFraction.

To do this, we can cross-multiply. When we cross-multiply StartFraction 7 over 3 EndFraction and another ratio, the product of the numerator of StartFraction 7 over 3 EndFraction and the denominator of the other ratio should be equal to the product of the denominator of StartFraction 7 over 3 EndFraction and the numerator of the other ratio.

Let's check each option:

1. StartFraction 9 over 49 EndFraction:

7 x 49 = 343

3 x 9 = 27

These values are not equal, so it is not a valid proportion.

2. StartFraction 18 over 42 EndFraction:

7 x 42 = 294

3 x 18 = 54

These values are not equal, so it is not a valid proportion.

3. StartFraction 42 over 18 EndFraction:

7 x 18 = 126

3 x 42 = 126

These values are equal, so it is a valid proportion.

4. StartFraction 49 over 9 EndFraction:

7 x 9 = 63

3 x 49 = 147

These values are not equal, so it is not a valid proportion.

Therefore, the ratio that results in a valid proportion when set equal to StartFraction 7 over 3 EndFraction is StartFraction 42 over 18 EndFraction.

Explanation:

Triangle ABC is isosceles because AC = BC.

The angles opposite these congruent sides are angle ABC and angle BAC. These are the base angles.

For any isosceles triangle, the base angles are congruent.

Angle BAC = 69 degrees is given. So angle ABC = 69 as well.

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

The missing angle must add to the two other angles so that all three angles in a triangle add to 180

(angle ABC) + (angle BAC) + (angle BCA) = 180

69 + 69 + (angle BCA) = 180

138 + (angle BCA) = 180

angle BCA = 180-138

angle BCA = 42

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

Angle DCE is congruent to angle BCA because they are vertical angles.

Triangle DCE is a right triangle. The missing angle is 90-(angle BCA) = 90-42 = 48

angle EDC = 48 degrees

Oscar owns his own towing and auto repair service. He charges $45 for towing and $20 per hour, h, for labor. There is an additional charge for parts, p. Oscar uses this formula to determine the total cost, C, for towing and repairing a car. C = 45 + 20h + p What is the total cost, C, to tow and repair a car that requires four hours of labor and $109 worth of parts?

Answers

Answer:

24,28-11 that the answer

Step-by-step explanation:

Total cost C =$229 to tow and repair a car that requires 4hours of labor and $109 worth of parts.

What is total cost?

"Total cost is defined as the sum of all the expenses which is required to produce a product."

According to the question,

C=total cost,

h= hour of labor

p = additional charges for parts

Total cost given as

C= 45 +20h + p

h = 4hour

p = $109

Substitute the value in the total cost we get,

C = 45+20(4) +109

   =$229

Hence, total cost C =$229 to tow and repair a car that requires 4hours of labor and $109 worth of parts.

What is the distance, to the nearest whole number, from K (5, 6) to P (1, 1)?

Answers

Answer:

The answer is 6 units

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

K (5, 6) P (1, 1)

The distance from K to P is

[tex] |KP| = \sqrt{ ({5 - 1})^{2} + ({6 - 1})^{2} } \\ = \sqrt{ {4}^{2} + {5}^{2} } \\ = \sqrt{16 + 25} \\ = \sqrt{41} \\ = 6.403124[/tex]

Norris currently has an account balance of $3,703.05. He opened the account 25 years ago with a deposit of $1,725.95. If the interest compounds monthly, what is the interest rate on the account? (3 points)

Answers

Answer:

R = 3.057% per year

Step-by-step explanation:

This is a compound interest question

From the question, we have the following information

P = Principal = $1,725.95.

A = Amount after 25 years = $3,703.05

T = Time = 25 years

n = Compounding frequency = compounded monthly = 12

r = interest rate = ???

The formula to calculate the interest rate in a compound interest question =

r = n[(A/P)^1/nt - 1]

r = 12[($3,703.05/$1,725.95)^1/12× 25 - 1]

r = 3.057%

Therefore, the interest rate on the account is 3.057%

Pentagon JKLMN is similar to pentagon VWXYZ. What is the measurement of angle X? Group of answer choices 60o 120o 150o 30o

Answers

Answer: Choice A) 60 degrees

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

Explanation:

Based on the diagram, angles L and X are the top most angles. They correspond to have angle L = angle X = 60 degrees

Though you shouldn't rely solely on a diagram because the figures may be oriented in a strange way. A better way is to look at the letter sequences of JKLMN and VWXYZ

Notice how L and X are the third letters of JKLMN and VWXYZ respectively. This means the letters pair up and are congruent angles (since the polygons are similar). So this is a non-visual way to see how angle L = angle X = 60.
