Answer:

Step-by-step explanation:

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share, now when you have a polynomial, the greatest common factor (GCF) of a polynomial is the largest monomial that divides evenly into each term , so

                            [tex](GCF)\\x^4=x^4\\x^5=x^4.x\\x^7=x^4 x^3\\(GCF)=x^4 \\[/tex]

Answer:

D) infinitely many solutions

Step-by-step explanation:

5 ( x-3 ) - 3x = 8x - 15 - 6x

5x - 3x - 15 = 8x - 6x - 15

2x - 15 = 2x - 15

2x = 2x

Since, equations of both lines are same. Therefore, there are infinitely many solutions.

Answer:

D

Step-by-step explanation:

Given

5(x - 3) - 3x = 8x - 15 - 6x

5x - 15 - 3x = 2x - 15

2x - 15 = 2x - 15

Since both sides are the same then any real value of x will be a solution.

That is there are infinitely many solutions

Answer:

  85°

Step-by-step explanation:

The sum of arcs in a circle is 360°.

  FG +140° +80° +55° = 360°

  FG = 360° -275°

  FG = 85°

Answer:

x > -1

Step-by-step explanation:

-3x + 15 < 18

Subtract 15 from each side

-3x + 15-15 < 18-15

-3x < 3

Divide each side by -3, remembering to flip the inequality

-3x/-3 > 3/-3

x > -1

Answer:

There are 20 students in the class

Step-by-step explanation:

Let the total number of children in the class be = x

from the question, we know that 20% of all the children are left-handed. We also know that 20% of the total children in the class = 4.

This means that 20% of  x = 4

Wherever we see the word "of" in an arithmetic problem, we should know that it infers a multiplication there.

Hence, we have

[tex]\frac{20}{100} \times x = 4[/tex]

[tex]x = \frac{4 \times 100}{20}= 20[/tex]

There are 20 children in the class altogether

Answer:

A

Step-by-step explanation:

Ok first we need to find rate of MILES per HOUR

320/6.4=50

m= miles in 9 hours

9*50=450

is your answer

A

(6.4*9)/320m=Hours/miles

Hope this helps!

The number of miles the bus will travel in 9 hours will be 6.4 / 320 = 9 / m. Then the correct option is B.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A bus travels 320 miles in 6.4 hours. if the bus continues at the same rate.

We know that speed is the ratio of distance and time. Then we have

The number of miles the bus will travel in 9 hours will be

320 / 6.4 = m / 9

6.4 / 320 = 9 / m

Then the correct option is B.

Answer:

471.24 yd²

Step-by-step explanation:

The formula for the surface area of the cylinder

= 2πr(r + h)

Height = 10 yd

Radius = 5 yd

Surface area =

2 × π × 5(5 + 10)

= 471.24 yd²

The surface area of the cylinder = 471.24 yd²

Answer:

b

Step-by-step explanation:

i just took it on edge

Line c is a transversal of lines a and b. The blank space filled by b

According to the question blank statement is to be filled.
Line c intersects lines a and b. Line d intersects lines a and b
In the diagram, line c is a transversal of lines a and _____

A line is the shortest distance between two points or a straight curve with zero deflection in it.

Here,
If c intersects line a and line b, then line c is the transversal line for both a and b.

Thus, line c is a transversal of lines a and b.

Answer:

The answer is 28.

Step-by-step explanation:

Ok.

☆7x and 3x + 16 are congruent, meaning they equal the same.

☆Since they are equal, we can make an equation out of then.

7x = 3x + 16

☆Then we just solve.

[tex] \: \: \: \: \: \: \: \: \: 7x = 3x + 16 \\ \frac{- 3x = - 3x}{4x = 16} \\ \\ \frac{4x}{4} = \frac{16}{4} \\ \\ x = 4[/tex]

☆Therefore, x equals 4.

☆We are solving for m<KJL so all we need to do is plug in.

[tex]7x \\ 7(4) \\ 28[/tex]

☆You answer is 28.

The required angle is 28°

Two triangles are said to be congruent if all three corresponding sides are equal and all three corresponding angles are equal in measure. These triangles can be slid, rotated, flipped, and turned to be looked identical. If repositioned, they coincide with each other.

Given here ∠KJL=7x and ∠LJM=3x+16

now in ΔKJL & ΔLJM, JL is common and KL=LM, and by Pythagoras  theorem JL²=KL²+JK² & JL²=JM²+LM²

Thus   KL²+JK² = JM²+LM²

⇒        JK=JM

Thus by the SSS criterion, we can conclude that the triangles are congruent.

therefore by CPCT 7x=3x+16

                                4x=16

                                 x=4

so the required angle is 7×4 =28°

Hence, ∠KJL=28°

Answer:

£573.40

Step-by-step explanation:

Amount = cost price - total depreciation

depreciation (1st year ) = 5% of £780

                     = [tex]\frac{5}{100}[/tex] x 780

                     = 0.05 x 780

                     = £39.00

depreciation (2nd year) = 5% of  £741

                                       =  £37.05

depreciation (3rd year) = 5% of 703.95

                                      = £35.1975

depreciation (4th year)  = 5% of 668.7525

                                       = £33.437625

depreciation (5th year) = 5% of 635.314875

                                      = £31.76574375

depreciation (6th year) = 5% of 603.5491313

                                      = £30.17745656

Total depreciation = £39.00 + £37.05 + £35.1975 + £33.437625 +   £31.76574375 + £30.17745656

                               = £206.6283253

Total depreciation = £206.6283253

Therefore,

Amount after 6 years = £780 - £206.6283253

             =  £573.3716747

             =  £573.40

The worth of the TV after 6 years is £573.40.

Q.1 360° Q.2 360°

Step-by-step explanation:

Q.1 let the third angle of the triangle be a

70°+40°+a=180(by angle sum property)

110°+a=180

a=180°-110°

a=70°

angle x=70°+x=180°(linear angle)

x=180°-70°

x=110°

angle z= 40°+z=180

z= 180°-40°

z=140°

angle y=a+y=180°

70°+y=+80°

y=180°-70°

y=110°

y+z+x=110° +110° +140°=360

Q.2 let the fourth angle of the quadrilateral be x

120°+70°+60°+ x=360° (by angle sum property)

250°+x=360°

x=360°-250°

x=110°

angle a=120°+a=180°(by linear angle)

a=180°-120°

a=60°

angle b=70°+b=180°

b=180°-70°

b=110°

angle c=x+c=180°

110° + c=180°

c=180°-110°

c=70°

angle d=60°+d=180°

d= 180° -60°

d=120°

a+b+ c+d=120°+110°+60°+70°=360°
