Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would solve a similar question:
Find the distance between the two points shown on the coordinate plane. (Round your answer to the
nearest tenth.)
Solution:
The coordinate plane is a plane formed by the intersection of the vertical line and the horizontal line. The vertical line is known as the y axis and the horizontal line is the x axis. The y axis and x axis intersect at a point known as the origin.
The distance between two points
on the coordinate plane is given by:
![Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}](https://tex.z-dn.net/?f=Distance%3D%5Csqrt%7B%28y_2-y_1%29%5E2%2B%28x_2-x_1%29%5E2%7D)
Given points (-2, -1) and (2, 3), the distance is:
![Distance=\sqrt{(3-(-1))^2+(2-(-2))^2}=\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{32}](https://tex.z-dn.net/?f=Distance%3D%5Csqrt%7B%283-%28-1%29%29%5E2%2B%282-%28-2%29%29%5E2%7D%3D%5Csqrt%7B4%5E2%2B4%5E2%7D%3D%5Csqrt%7B16%2B16%7D%3D%5Csqrt%7B32%7D)
# of numbers between 1 & 103: 102
Half of that would be even numbers. So, 51 even numbers.
Between 4 and x, there are 102 numbers. 4+102=106. 4+106=x. 106=x
Answer:
x=35
Step-by-step explanation:
55+90=145
