Answer:

  20

Step-by-step explanation:

120/6

Answer:

60 minutes

Step-by-step explanation:

First, lets write the problem into an equation

12 miles/120 minutes = 6 miles/x minutes

Then, we solve

12/120 = 6/x

12x = 720

x = 60

Therefore, your answer is 60 minutes

Answer:

$2 each

Step-by-step explanation:

If x is the price of 1 pencil, the equation is 22-5x=12

-5x=12-22

-5x=-10

5x=10

x=2

Each pencil was $2

Answer:

2/3xy.

Step-by-step explanation:

8x/12x^2y

The 8 and 12 simplify to 2/3 and x and x^2 simplify to 1/x so we have:

= 2/3xy.

Answer:

5319

Step-by-step explanation:

There are two ways that the answer can be determined

Method 1

0.1 x 5710 = 571

5710 - 571 = 5319

Method 2

If the plants planted this year are 10% fewer, the plants this year are (100% - 10%) 90% of last year's plant

90% x 5710

0.9 x 5710 = 5319

Answer and Step-by-step explanation:

The answer is 42°.

This is because we are given an Isosceles Triangle. Isosceles Triangles always have 2 legs/sides that are the same length, and because those two sides have the same length, it means their base angles have the same value as well.

So, Since the angles LKM and KML are the base pairs of this Isosceles Triangle, they are equal to each other.

Answer:

The surface area of the cone is;

68 π m^2

Step-by-step explanation:

Here, we want to get the surface area of the cone

Mathematically, we have this as ;

S.A = π(r^2 + rl)

where r is the radius and l is the slant height

We are given the diameter, but the radius is half of this

d = 8

r = d/2 = 8/2 = 4 m

l = 13 m

S.A = π(4^2 + 4(13))

= π(16 + 52) = 68 π m^2

Answer:

3 5/8

Step-by-step explanation:

6 4/8 - 2 7/8 = 4 -3/8 = 3 5/8

Answer:

I) 616

II) 4.53

Step-by-step explanation:

For the first one, just plug in 7 as R.

A = 4 x (22/7) x 7^2

A = 12.57142857 x 49

A = 616

For the second, one, put 452 4/7 as A.

452 4/7 also is 258.285

258.285 = 4 x (22/7) x r^2

258.285 = 12.57142857 x r^2

Divide both sides by 12.57142857

20.55372408 = r^2

Square root 20.55372408 for R.

4.533621519 = R

OR

4.53 = R

Step-by-step explanation:

Answer:

Part a) 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week, how many seconds are in a week

60x60=3600 x 24= 86400 x 7= 604800

So 604,800 seconds in a week

Part b) James and Kelly have $10 to spend at a grocery store. If they get 3 avocados which cost $1 each, 4 tomatoes which cost a total of $2 for all 4, and two loaves of bread which cost $2 each, how much change will James and Kelly receive after their purchase?

So 3 x 1= $3

+ $2

2 x 2= $4

3+2+4= $9

10-9= $1

So they'll get back $1

Answer:

A. x =2

Step-by-step explanation: Rearrange terms 3x - 8 = 6 ( 1 - 2x ) + 16 ---> 3x - 8 = 6 ( -2x + 1 ) +16

Distribute

Add the numbers

Add 8 to both sides of the equation

Simplify

Add 12x to both sides of the equation

Simplify

Divide both sides of the equation by the same term

Answer:

Step-by-step explanation:

Correct choice is D

[tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]  is the simplification of the given expression.

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are called PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

It is given an expression [tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }[/tex]

Simplifying the given expression using the PEMDAS technique,

[tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }\\\\\sqrt[4]{\frac{3x^2}{16y^4} }\\\\\frac{\sqrt[4]{3x^2}}{2y}[/tex]

Therefore, the simplified value of the given expression is [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]. Thus, the option D is correct.

2x²-3x-5

=2x²-3x-5

=2x²-5x+2x-5

=2x(x-5)+2(x-5)

=(x-5)(2x+2)

Answer:

(x + 1)(2x - 5)

Step-by-step explanation:

Assuming you require the expression factorised.

2x² - 3x - 5

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 5 = - 10 and sum = - 3

The factors are + 2 and - 5

Use these factors to split the x- term

2x² + 2x - 5x - 5 ( factor the first/second and third/fourth terms )

= 2x(x + 1) - 5(x + 1) ← factor out (x + 1) from each term

= (x + 1)(2x - 5) ← in factored form

Answer:

Step-by-step explanation:

Equation

2x + 2 + 3x - 1 + x +4 = 29             Collect like terms on the left

6x + 5 = 29                                     Subtract 5 from both sides

6x = 29 - 5

6x = 24                                            Divide by 6

x = 24/6

x = 4

Length of the Sides.

2x + 2 = 2*4+2 = 10

3x - 1 = 3*4 - 1 = 12 - 1 = 11

x + 4 = 4 + 4 = 8

Type of Triangle

Scalene.

Answer:

X = 3, Y = 1.

Step-by-step explanation:

X = 3 and Y = 1, because 2 times 3 equals 6, and 6 plus 1 equals 7. So that's for the first one, but now we need to make sure that it's the same value for the other equation. 3 times 3 equals 9, 4 times 1 equals 4, and 9 minus 4 equals 5. So X = 3, and Y =  1. Hope this helped :D

Answer:

The part of the expression that represents the number of quarters is;

D. 25·(3·x + 1)

Step-by-step explanation:

From the question, we have;

The values of the coins Luis has = Nickels, Dimes and quarters

The expression that represents the value of all the coins in cents is given as follows;

5(x + 2) + 10·1 + 25·(3·x + 1)

The value of a nickel = 5 cents

The value of a dime = 10 cents

The value of a quarter = 25 cents

Therefore, the part of the expression representing the number of quarters Luis has, has 25 as a factor

Therefore, the part of the expression that represents the number of quarters = 25·(3·x + 1).
