Use Power of a point.
(can prove using similarity of the triangle)
AC*CB = DC*CE
8*7 = 4*CE
CE = 14
DE = DC+CE = 4+14 = 18
Ans: 18
Answer:
Step-by-step explanation:
8x10^7
10^7 = 10,000,000
10 million times 8 = 80,000,000
5x10^5
10^5 = 100,000
100 thousand times 5 = 500,000
80,000,000 minus 500,000 = 75,000,000
so the distance from mason to chloe is 75,000,000 times greater than mason to kevin
i hope this was good, if it's not exactly what you need lemme know ^^

Answer:
75 students
Step-by-step explanation:
So firstly lets make convert these words to alegbra :
30 people are 40%of the total students at the event meaning that the following equation can be made :
30 = 40% of x (x is the unknown amount of students there)
30 = 40% * x
30 = 0.4x (we can convert the precentage into a decimal by dividing by 100)
Now that we have the equation that 30 = 0.4x we can evalute it and find x :
30=0.4x
30/0.4=0.4x/0.4 (divide by 0.4 on both sides)
75=x
So thats how we get that 75 students were in the event in total.
