Write a system of equations to describe the situation below, solve using any method, and fill in the blanks
Anna is thinking of two numbers. Adding 8 times the first number and 7 times the second
number gives a total of 13. Also, adding 2 times the first number and 5 times the second
number gives 13. What are the two numbers?

The first number is
and the second number is___

c

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²

um is there supposed to be a picture?
