4y-8>10
Add 8
4y-8+8>10+8
4y>18
Now divide both sides by 4
4y/4 > 18/4
y>9/2
Now let's see if it will be true
Replace y by its value
4(9/2)-8>10
36/2 -8 > 10
18-8 > 10
10 > 10
That's false because 10 can not smaller than 10
so it should be = instead
Answer : False
I hope that's help:)
Answer:
Option (1).
Step-by-step explanation:
In the figure attached,
Houses of three friends Jo, Boris and Carrie are located at the vertices of a triangle.
They want to meet at a place which equidistant from these vertices.
A point in a triangle which is equidistant from the vertices is its Circumcenter.
A circumcenter of a triangle is a point of intersection of perpendicular bisectors of its sides.
Therefore, the next step to find the meeting place should be,
Option (1). They should find the midpoint of the segments which connect their houses.
So for this you will be doing proportions. Your equation will look like this:
Firstly, cross multiply:
Next, square root both sides of the equation, and your answer should be

The distance he travels is 6+8=14 blocks. the straight line distance is the hypotenuse of a right triangle with legs 8 and 6.
6²+8³=c²
36+64=c²
100=c²
c= √100 = 10 blocks.
