hi
x- 3/5 = 5x/ 6
6x - 18/5 = 5x
6x -5x = 18/5
x = 18/5
let's check : 18/5 - 3/5 = 15/5 = 3
5 * 18/5 / 6 = 18/6 = 3
result is correct.
Answer:
the answer is
x + y + z = 180 degrees
proof
the sum of all angles in the triangles is always equal to 180 degrees
Step-by-step explanation:
Answer:
y = 4000 - 70x
Linear function.
Step-by-step explanation:
Let x = number of weeks.
In 1 week, he withdraws $70.
That means -70 in 1 week.
After the second week, he will have withdrawn 2 times $70, or
-70 × 2
After 3 week, he will have withdrawn -70 × 3
After x weeks, he will have withdrawn $70 × x,or simply -70x.
He starts with 4000, so after x weeks, he has 4000 - 7x.
Let y = the amount of money at week x.
The equation is
y = 4000 - 70x
This is a linear function.
1,000 cubic feet because the pyramid is 4000 cubic feet on an area base of 40.
