Answer:

X= -8

Step-by-step explanation:

First you distribute the 5 to the parenthesis to get 5x-30+4=7x-10. Then subtract 14 on both sides to get 5x-16=7x. Next, subtract 5x from both sides to get -16=2x. Now you divide by 2 on both sides to get -8=x.

Answer: x = - 8

Step-by-step explanation:

The first step in applying the distributive property:

5 (x - 6) + 4 = 7x - 10

5x - 30 + 4 = 7x - 10

The second step is to combine like terms by subtracting 10 from -30, and subtracting 4 from - 20:

5x - 30 + 4 = 7x - 10

5x - 16 = 7x

The third step is to subtract 5x from 7x:

5x - 16 = 7x

- 16 = 2x

The last step is to divide each side by 2 to isolate the variable, or find x:

- 16/2 = 2x/2

- 8 = x

or x = - 8

Answer:

a) i) The drawing of Zeno's route is attached

ii) The bearing of Zeno's return journey is 241° from point C to point A

b) Yes, Zeno returns to Port A before 5.15pm

Step-by-step explanation:

a) i) Please find attached the drawing of Zeno's route

ii) From the attached diagram of Zeno's route created with Microsoft Whiteboard, we find the bearing of his return journey as 241° from point C to point A

b) The distance from point C to point A = 10·√5 km

The speed with which Zeno sails as he returns = 10 km/h

The time it takes Zeno to return t = Distance/Speed

∴ The time it takes Zeno to return t = 10·√5 km/(10 km/h) = √5 h ≈ 2.2361 hours ≈ 2 hours 14 minutes and 9.845 seconds

The time Zeno arrives at point A from point A ≈ 3.00 pm + 2 hours 14 minutes and 9.845 seconds = 5:14.1641 p.m. ≈ 5:14 pm.

Therefore, Zeno returns to Port A before 5.15pm.

Answer:

110

Step-by-step explanation:

lets assume y is the angle next to x which should complete to form a 360.

50 + 25 + 35 + y = 360

y = 250

x + y = 360

x + 250 = 360

x = 110

Answer:

110

Step-by-step explanation:

lets assume y is the angle next to x which should complete to from a 360.

50 + 25 + 35 + y = 360

y = 250

x + y = 360

x + 250 = 360

x = 110

Answer:

DG = 26

GE = 26

DF = 15

CH = 14

CE = 28

Step-by-step explanation:

Find the image attached for the complete question

IF If J is the centroid of CDE, this means that J divides CG, FE, DC, CE and DH into two equal parts.

The following expressions are therefore true

DG + GE = DE and DG = GE

Substituting

DG + DG = DE

2DG = DE

Given DE - 52

2DG = 52

DG = 52/2

DG = 26

Since DG = GE, hence GE = 26

Also DF + FC = DC and DF = FC

Since FC = 15, hence DF = 15

Also CH + HE = CE and CH = HE

Since HE = 14, hence CH = 14

CE = 14+14

CE = 28

DG = 26, GE = 26, DF = 15, CH = 14, CE = 28

IF If J is the  centroid of CDE, this means that J divides CG, FE, DC, CE and DH into two equal parts

Therefore,

DG + GE = DE ....(1)

DG = GE ...(2)

Substituting (2) in (1) ,we get

DG + DG = DE

2DG = DE

Also, DE = 52  (Given)

So, 2DG = 52

DG = 26

As, DG = GE,

Therefore,  GE = 26

Also,  DF + FC = DC and DF = FC

As, FC = 15,

So, DF = 15

Also CH + HE = CE and CH = HE

Since HE = 14,

So, CH = 14

CE = 14+14=28

So, CE = 28

Therefore, DG = 26 , GE = 26, DF = 15, CH = 14, CE = 28

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

It factors to (a+b)(a-b).

Step-by-step explanation:

A binomial is an expression with only terms where at least one is a term with a variable. When we can factor for difference of squares, we can have two variable terms or just one with a constant.

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

Answer:

a) 3/5=12/20

b) 5/6=25/30

Step-by-step explanation:

a.) To find the answer you would first find how much it took to get to 20. 5  times 4 is 20. Then to find the numerator you would do 3 times 4 and that would be 12.

b) To find the answer you would first find how much it took to get to 30. So 30/6 is 5. Then you would divide 25 by 5 and you would get 5.

Answer:

I think what you got is correct

The percentage of incorrect problems is 25%.

Option D is the correct answer.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of problems = 20

Number of correct problems = 15

The number of incorrect problems.

= 20 - 15

= 5

The percentage of incorrect problems.

= 5/20 x 100

= 25%

Thus,

25% were incorrect problems

Answer: B. -4 < y < -1

Step-by-step explanation:

1. Subtract 2 from all three sides to isolate the variable in the center of the inequality

5 < 2 - 3y < 14

3 < -3y < 12

2. Divide each of the three sides by -3 to get y by itself, as each of the answers have y as independent.

Answer:

The difference in area is 672 cm^2

Step-by-step explanation:

Firstly, let us get the diameter of the circle

The length of the wire is the measure of the circle’s circumference

mathematically;

C = pi * d

176 = 22/7 * d

22d = 7 * 176

d = (7 * 176)/22

d = 56 cm

So, the area of the circle will be;

pi * d^2/4

= 22/7 * 56 * 56 * 1/4

= 2464 cm^2

Also, the length of the circumference is same as the perimeter of the rectangle

From the perimeter of the rectangle, we can get the width and use that to calculate the area of the rectangle

The formula for the perimeter of the rectangle is;

2(l + b)

2(56 + b) = 176

56 + b = 88

b = 88-56

b = 32 cm

So, the area of the rectangle will be;

32 * 56 = 1792 cm^2

The difference between the two areas will be;

2464-1792 = 672 cm^2

Answer:

k = ±6

Step-by-step explanation:

guess your question is 4k²–144 = 0??

4k² = 144

k² = 36

k²–36 = 0

(k+6)(k–6) = 0

k+6 = 0 | k–6 = 0

k = –6, k = 6.

Alternatively; k = ±6.

Answer:

Step-by-step explanation:

-5x - 4y = 2a                         4x - 5y = 2

-4y = 5x + 2a                        -5y = -4x + 2

y = (5x + 2a):(-4)                    y = (-4x + 2):(-5)

y = -⁵/₄x - ¹/₂a                           y = ⁴/₅x - ²/₅

m₁ = -⁵/₄,  b₁ = -¹/₂a                  m₂=⁴/₅,  b₂= -²/₅

               -⁵/₄ ≠ ⁴/₅

Different slopes means that two lines have one point of intercept (no mater what the b's are). That means that the system of linear equations has exactly one solution for any value of a.

Answer:

Step-by-step explanation:

[tex](2x - \frac{1}{3} ) - ( \frac{2}{x} + 1)[/tex]

[tex]2x - \frac{1}{3} - \frac{2}{x} + 1[/tex]

[tex](2x - \frac{2}{x} ) + ( - \frac{1}{3} + 1)[/tex]

[tex] (\frac{2 {x}^{2} }{x} - \frac{2}{x} ) + ( \frac{ - 1}{3} + \frac{3}{3} )[/tex]

[tex] \frac{2 {x}^{2} - 2 }{x} + \frac{ - 2}{3} [/tex]

We want to write the given expression as a single fraction. We will get the fraction:

[tex]\frac{6*x^2 - 4*x - 6}{3*x}[/tex]

So we start with the expression:

[tex](2*x - \frac{1}{3}) - (\frac{2}{x} + 1)[/tex]

First, let's rewrite each of these parenthesis as fractions, we need to have the same denominator in all the terms, then in the first one we can multiply and divide by 3 (and in the second one we can do the same but with x) so we get:

[tex](\frac{3}{3} *2*x - \frac{1}{3}) - (\frac{2}{x} + 1*\frac{x}{x} )\\\\(\frac{6*x}{3} - \frac{1}{3}) - (\frac{2}{x} + \frac{x}{x} )\\\\\frac{6*x - 1}{3} - \frac{2 + x}{x}[/tex]

Now we must multiply and divide the left term by x, and the right term by 3, so we get:

[tex]\frac{x}{x} \frac{6*x - 1}{3} - \frac{2 + x}{x}*\frac{3}{3} \\\\\frac{6*x^2 - x}{3*x} - \frac{6 + 3x}{3*x} = \frac{6*x^2 - x - 3x - 6}{3*x}\\\\\frac{6*x^2 - 4*x - 6}{3*x}[/tex]

This is the fraction in its simplest form.
