I don't know. can someone help please??​

Step-by-step explanation:

27 = x + 3x +5x

27 = 9x

3 = x

Board 1: (3)(1) = 3 inches

Board 2: (3)(3) = 9 inches

Board 3: (3)(5) = 15 inches

Length of the first piece is 3 inches

Length of the second piece is 9 inches

Length of the third piece is 15 inches

An equation is a mathematical statement which equate two algebraic expressions. An equation has an equal to (=) sign in between the expression.

According to the problem,

∴ Length of the second piece = 3x inches

∴ Length of the third piece = 5x inches.

Now, all these pieces will add up to 27 inches.

∴ x + 3x + 5x = 27

⇒ 9x = 27

⇒ x = 3

Length of the first piece = 3 inches

Length of the second piece = (3 x 3) inches = 9 inches

Length of the third piece = (5 x 3) inches = 15 inches

Answer:

20:£1

Step-by-step explanation:

To simplify a ratio is like like simplifying a fraction

Take 4/8 as an example. Find a number you can divide both numbers with. In this case, it's 4. 4 divided by 4= 1, and 8 divided by 4= 2. So, the simplified version of 4/8 is 1/2. Similarly, with the ration 60:£3, you find the number you can divided both numbers with. In this case, it is 3. 3 divided by 3= 1, and 60 divided by 3= 20.

Final Answer: 20:£1

Perimeter of rectangle = 26

Length is 7 less than 9 times the width.

We have to find the width of rectangle[tex].[/tex]

_________________________________

Let, width of rectangle be x therefore length of rectangle will be (9x - 7)

We know that, perimeter of rectangle is given by

⇒ perimeter = 2 (l + b)

⇒ 26 = 2 [(9x - 7) + x]

⇒ 13 = x + 9x - 7

⇒ 20 = 10x

⇒ x = 2 (width)

Step-by-step explanation:

Let breadth be x

As it is given that, the Length is 7 less than 9 times :

Therefore, Length will be 9x - 7

Perimeter of reactangle = 26

➳ 2 ( Length + Breadth) = 26

➳ 9x - 7 + x = 26/2

➳ 10x = 13 + 7

➳ 10x = 20

➳ x = 2

Answer:

No

Step-by-step explanation:

The literal equation a = 3b + 4c - a contain "a" on the right side so it is not solved for a.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

If we solve any equation for x then

x = f(other than x)

For example

x + 2x + 3y = 4

Solve for x will be

3x + 3y = 4

x = (4 - 3y)/3 so on right-hand side no x term is present.

Given the equation,

a = 3b + 4c - a

The right-hand side has termed "a" so it is not solved for a.

Hence "The literal equation a = 3b + 4c - a contain "a" on the right side so it is not solved for a".

Step-by-step explanation:

BTW i'm probably wrong because my mom says i suck at math but friend me please lol

Answer:     1   19/24 ft

Step-by-step explanation: You multiply the fractions by the numbers needed to get the common denominator of 24 in this case 5/8 (put the two to the side for now.) multiply both top and bottom by 3 which will get you 15/24 then the whole number 2, your going to take it and subtract one from it so now there is only one whole number then with the one you subtracted you multiply (1x24)+15 *for the numerator* so now its 39/24 and for the second fraction 5/6 multiply both top and bottom by 4 now your fraction is 20/24 now...--> 39/24 - 20/24=19/24 and the left over whole number from the beginning goes down in front so the final answer is 1 19/24

Answer:

C. 17

Step-by-step explanation:

I'm assuming you need the hypotenuse so to get that you do

The square root of a^2 + b^2

                            a squared + b squared

So it becomes square root of 8^2 + 15^2

                    =   square root of 64 + 225

                    =   square root of 289

                    =   17

Answer:

A and B

Step-by-step explanation:

Answer:

m =-4

Step-by-step explanation:

-12m-10=-5m+18

add 5m to both sides

-7m-10=18

add 10 to both sides

-7m=28

divide both sides by -7

m= -4

Answer: m = -4

Step-by-step explanation: First distribute to get -12m -10 = -5m+18, then add 5m on both sides to get -7m -10 = 18, then add 10 on both sides to get -7m = 28, finally divide by -7 on both sides to get m = -4.

Answer:

Henry needs 15 pints of paint altogether

Step-by-step explanation:

If Henry uses 2 pints of red paint and 3 pints of yellow paint to get a specific color, and he now uses a total of 9 pints of yellow, then

3 x 3 = 9 (yellow)

We know that what you do on one side, you do on the other.

2 x 3 = 6 (red)

You add

9 + 6 = 15. (Red and yellow paint)

Which will lead you to the conclusion of 15 pints.

Answer:

Henry will need 15 pints altogether.

Step-by-step explanation:

Add: 6 + 9 = 15 pints
