How do I evaluate an algebraic expression

Mathematics
1 answer:
xxMikexx [17]3 years ago
6 0

Answer:

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

there are 18 lions, tigers and bears. If the number of lions is 4 less than 3 times the number of bears and the number of tigers
Harlamova29_29 [7]

bears = x \\ lions = 3x - 4 \\ tigers =  \frac{ 3}{4}x + 3

all you have to do next is add all of them in one equation and equate them to 18

when you find x, replace in each expression to get your answers

Which of the following points is an equal distance (equidistant) from a(2, −2) and b(−4, 6)?
lesantik [10]
The point equidistant from a(2, -2) and b(-4, 6)  is the midpoint

For (x₁, y₁) and (x₂, y₂) the midpoint is given by:

 ( (x₁ + x₂)/2 ,  (y₁ + y₂)/2 )

Midpoint = ( (2 + -4)/2 , (-2 + 6)/2 )

               =  ( (2 - 4)/2 ,  (6 - 2)/2) ) = ( -2/2,  4/2) = (-1,  2)

So the point equidistant from the two points is (-1, 2).

I need help please and thank you

Well I THINK triangle ABC is just a stretched out version of triangle DEF.

To find the area of a triangle, you multiply base and height, and divide by 2.

Area of DEF is 6, so that means that (4 * x)/2 = 6.

6*2 = 12....

4 * x = 12........

4 * 3 = 12.

x = 3.

Comparing DEF to ABC: ABC's base is 3 times as long as DEF's. So that means the height must be three times as long.

3*3 = 9.

(12 * 9)/2 =54
