A math expression is anything where you take one or more numbers and add them, subtract them, multiply, divide, etc etc

For example, 2+3 is a math expression

To make it an algebraic expression, we replace one of the numbers with a variable. Often this is the letter x. So let's say we replace the 2 with x. That would have the expression turn into x+3. What we're saying is "some number plus 3"

Normally 2+3 = 5 which is a true equation. Replace the 2 with x and we have x+3 = 5. So we're saying "some number plus 3 is 5". You can guess and check to find that the "some number" has to be 2

--------------------------------------

In summary, the expression example was x+3 and the equation was x+3 = 5

Note: an equation is simply two expressions set equal to each other.

Does anyone know what 64.4 as a fraction is?​
klasskru [66]

As a mixed number, it's 64 and 4/10:

      64\frac{4}{10}

As an improper fraction, it's 644/10:

    \dfrac{644}{10}

This can also be reduced to 322/5:

    \dfrac{322}{5}

The following triangle is an isosceles triangle. What is the length of the missing side?
OLga [1]

Considering that we have an isosceles triangle, the length of the missing side is of 11 inches.

<h3>What is an isosceles triangle?</h3>

An isosceles triangle is a triangle that has two congruent sides.

Researching this problem on the internet, the triangle has two sides of 4 in and 11 in, and one missing side. The missing side is opposite to the side of 4 in, with the same scale, hence the length of the missing side is of 11 inches.

Li-Ming owns an ice cream shop. On Saturday evening from 6:00 PM to 7:00 PM, 80 people entered her shop. On Tuesday from 3:00 PM
KengaRu [80]
To find the percent decrease from Saturday to Tuesday, you will find the difference between the number of customers on those days and divided by the total number of customers on Saturday.

By dividing this you will get a decimal, which then can be converted to a percent.

80-17= 63

63/80 = 0.7875
0.7875 = 78.75%

There was a 78.75% decrease from Saturday to Tuesday.

A surveyor found the angle of elevation from the ground to the top of the building at two locations 20 feet apart as shown below
Serga [27]

Applying the sine ratio and law of sines, the correct measurements are:

B. m∠B = 15°

E. h ≈ 31.28 ft.

<h3>What is the Sine Ratio?</h3>

Sine ratio that can be used to determine the side length of a right triangle is, sin ∅ = opposite side/hypotenuse.

Find c using the law of sines:

C = 33°

A = 180 - 48 = 132 [linear pair]

B = 180 - 33 - 132 = 15° [triangle sum theorem]

b = 20 ft

c = ?

Using the law of sines, b/sin B = c/sin C, we have:

20/sin 15 = c/sin 33

(c)(sin 15) = (20)(sin 33)

c = (20 × sin 33)/sin 15

c ≈ 42.09

Use the sine ratio to find h:

∅ = 48°

Hypotenuse = c = 42.09

Opposite = h = ?

sin 48 = h/42.09

h = (sin 48)(42.09)

h ≈ 31.28

The correct measurements are:

B. m∠B = 15°

E. h ≈ 31.28 ft
