How do you write an equation to represent a real-world situation?

1 answer:

4 0

You have to organize the parameters of the real-world situation that is known and unknown. Also, you have to distinguish which of them are dependent and independent. Next, you assign letters as your variables. Lastly, you make an algebraic expression by translating the relationship into the mathematics.

30 POINTS + BRAINLIEST!!! PLEASE HELP ASAP!!!

Oliga [24]

Answer:

CNBD

Step-by-step explanation:

From the diagram, we can see that:

$\displaystyle BL\parallel CA$

Then by Alternate Interior Angles:

$\angle LBA\cong \angle CAB\text{ and } \angle BLC\cong \angle ACL$

From vertical angles, we also know that:

$\displaystyle \angle BKL\cong \angle AKC$

This is all we can gather from the given image. Knowing only three pairs of angles cannot prove congruence, as proving congruence requires at least one side.

Congruence cannot be determined.

Area of a rectangle with a width of 36cm and a perimeter of 80cm

grandymaker [24]

The area would be 144cm^2.

In order to find the area, we need to know the length of the rectangle. We can find that using the perimeter formula.

2l + 2w = P

2l + 2(36) = 80

2l + 72 = 80

2l = 8

l = 4

So now that we know the length is 4, we can find the area using that formula.

A = lw

A = (4)(36)

A = 144
