A student claims that 3x + 2y = 5xy. Use a visual representation to show whether this is true or false

Answer:

= 18.857 cm²

Step-by-step explanation:

The area of a segment is given by;

θ/360 × 2πr². where θ is the angle subtended by the arc to the center of the circle and r is the radius of the circle.

θ = 60, and r = 6

Therefore;

Area = 60/360 × 22/7 × 6²

        = 18.857 cm²

Answer:

6π - 9 √3 square units

Step-by-step explanation:

The person above me is right, but this is all they are asking for in the problem. I hope it helps!

Let the unknown number be x then given,

(4/5)x - (3/4)x = 4

(16x - 15x)/20 = 4

x/20 = 4

x=80

Let the number be n.

Four fifths of the number is 4n/5.

Three fourths of the number is 3n/4.

Four fifths of a number is more than three fourths of the number by 4.

4n/5 = 3n/4 + 4

20 * 4n/5 = 20 * 3n/4 + 20 * 4

16n = 15n + 80

n = 80

Let's check.

4/5 of 80 = 4/5 * 80 = 64

3/4 of 80 = 3/4 * 80 = 60

64 is indeed 4 more than 60 showing that 4/5 of 80 is 4 more than 3/4 of 80, so 80 is correct.

Answer: 80

Answer:

The question is asking for the length. The height is given as 6 and the width is given as 5. The length is unknown

To find the length use formula lxwxh=volume

We know the volume of each bin to be 360 so we plug into the formula

lx5x6=360 (multiply)

lx30=360 (divide both sides by 30 to isolate the unknown, which is the length).

360/30= 12

l=12

The length is equal to 12

The answer is 12.

Step-by-step explanation:

Part (a)  We shall simplify both of them in order to find the solution to the equation.

• Once we've done that, we'll see that they have the same equation, so we can match the equation if x=10.

Part (b)  When x=-1/2, the answers to the second expression, 2x2, change to -1, and we eventually arrive in 1.

• This is why the expressions are not equal at this point.

Part (c)  As we can see, the expressions are identical, thus we can demonstrate that they are equal if x is any number other than -1/2.

What is an expression in maths?

• An expression is a set of terms combined using the operations +, – , x or , for example 4 x − 3 or x 2 – x y + 17 .
• An equation states that two expressions are equal in value, for example 4 b − 2 = 6 .
• An identity is a statement that is true no matter what values are chosen, for example 4 a × a 2 = 4 a 3 .

What is a math expression example?

• An expression is a set of numbers or variables combined using the operations +, –, × or ÷.
• Arithmetic expression that contains only numbers and mathematical operators and algebraic expression that contains variables, numbers and mathematical operators.

How do you find expressions?

• To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number.
• To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

Answer:

Part a)  In order to solve the equation, we will simplify both of them.  Once we do that, if we notice, they are the same equation, so therefore, if x=10, then we will be able to match the equation.

Part b) The reason the expressions are not equal when x=-1/2 is because if we see, that in the second expression, 2x^2, if x=-1/2, then the answer becomes -1, and we eventually end up with 1.

Part c)  As we can see, the expressions are the same, so if x is any number other than -1/2, then we will be able to show that the expressions are equal.
