I'll do 14 and 18, and you can apply those techniques for the other problems!
For 14, we get 30*(1/10^8). This means that you move the decimal place in 00.0000030.0 seven places to the left, resulting in 0.00000300
For 18, we can use the associative property of multiplication to get
5*3.5*10^3*10^(-1)=17.5*10^2. We get 10^2 by adding 3 and -1 up. Since it's positive 2, we simply move the decimal 2 places to the right to get 1750
Y = -4/5x + 8/5 (slope intercept form is y = mx + b)
Answer:
52
Step-by-step explanation:
Where you see the letters substitute with the number.
6(5)(2) - 2(4)
60 - 8
=52
Answer:
The value of x = 11
Step-by-step explanation:
Given
≅ 
Determining the value of x
As B is between A and C, so
≅ 
as
so
x + 5 = 2(x-3)
x+5 = 2x-6
2x-x = 5+6
x = 11
Therefore, the value of x = 11

You can get this by using the quadratic equation with a = 7, b = -1, c = -9
