2x+5 would be the equation
x is the "number" that is unknown, it's what's called a variable. Because you need two times a number(x) you put a coefficient of 2 in front of it, then simply add 5.
Examples with known variable values:
2(4)+5=13
2(2)+5=9
Answer:
Yes
Step-by-step explanation:
Since the sides are each congruent then ABCD and PQRS are the exact same shape and size. This means the area inside each figure will be the same amount. The areas are the same.
Answer:
no
Step-by-step explanation:
1 4/5 = 1 8/5 if you make a common denominator
The value of a is 80
Step-by-step explanation:
The distance of a point
from the y-axis can be written as

because the x-coordinate of the y-axis is zero.
Similarly, the distance of a point
from the x-axis can be written as

Since the y-coordinate of the x-axis is zero.
In this problem:
- The distance of the point A (−30, −45) from the y-axis can be written as

- The distance of point B (a,a) from the x-axis can be written as

Since
.
We are told that 2/3 of the distance from the y-axis to point A (−30, −45) is equal to 1/4 of the distance from the x-axis to point B(a, a), which means

Therefore,

And solving for a,
