Answer:

C. 13

Step-by-step explanation:

4x+1 = 6x-5

    -1         -1

4x= 6x-6

-6x   -6x

-2x=-6

divide by -2

x=3

4(3)+1

12+1

13

Answer:

13

Step-by-step explanation:

6x-5=4x+1 (subtract 4x from both sides and then add 5 to both sides)

2x=6 (divide by 2)

x=3

Substitute 3 for x

6(3)-5 =18-5=13 or 4(3)+1=12+1=13

Answer: B

I got it right :)

The length of a side of this triangle can be expressed as (2x - 3)

An equilateral triangle is a triangle in which all three sides have the same length and all three angles are 60°.

Given that, the perimeter of an equilateral triangle is represented by (6x-9)

Let a be the side of the triangle,

3a = 6x - 9

a = 2x - 3

Hence, The length of a side of this triangle can be expressed as (2x - 3)

1/2x+5=10

subtracting 5 from both sides 1/2x+5-5=10-5

1/2x=5

divide both sides by 1/2

1/2x÷1/2=5÷1/2

x=5×2/1

x=10

-13/2

Step-by-step explanation:

Answer:

P = -6.5

Step-by-step explanation:

Multiply -2 x p and -2 x -1

The equation now is -2p + 2 = 15

Subtract the 2 to both sides to cancel it out

The equation now is -2p = 13

Divided both sides by -2 to isolate the p variable

p = -6.5

You can check your answer by subtracting -6.5 by -1 (which equals -7.5)

And then multiply -7.5 by -2 which equals 15

May 12th

Step-by-step explanation:

On 12th they both practice together.

Least Common Multiple is the meaning of the abbreviation LCM. The lowest number that may be divided by both numbers is known as the least common multiple (LCM) of two numbers. It can also be computed using two or more numbers. Finding the LCM of a given collection of numbers can be done in a variety of ways.

In mathematics, the least common multiple is sometimes referred to as LCM or the lowest common multiple. The smallest number among all the common multiples of the provided numbers is the least common multiple of two or more numbers.

Given:

Matt  practice every fourth day.

I practice on 3rd days

Now, to find the first date on which they both have practice we have to find the LCM

So, 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40

3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

Hence, On 12th they both practice together.

Answer:

English homework = 19/30h or 38 minutes

Total time spent = 22/15h or 88 minutes

Step-by-step explanation:

Mathematics homework = 5/6h

= 5/6 × 60

= 300/6

= 50 minutes

He took 1/5 h less to complete his english homework.

English = 5/6h - 1/5h

= 25h-6h/30

= 19/30h

= 19/30 × 60

= 1,140/30

= 38 minutes

English homework = 19/30h or 38 minutes

Total time spent on his homework = mathematics homework + English homework

= 5/6h + 19/30h

= 25h+19h/30

= 44/30h

= 22/15h

= 22/15 × 60

= 1,320 / 15

= 88 minutes
