Answer: 3
Step-by-step explanation:
Let the smaller number be y.
Since the difference of two numbers is 5,then the larger number will be: y+5
The sum of three times the larger number and twice the smaller number is 30. This can be written as:
3(y+5) + 2y = 30
3y + 15 + 2y = 30
5y + 15 = 30
5y = 30 - 15
5y = 15
y = 15/5
y = 3
The smaller number is 3
5 miles high is one of the sides of a triangle depending on accuracy level
h^2=x^2+y^2
we don't have 2 distances
Tan A=O/a
O=a tan A
We solve for O because the angle is at the top of the line going up and we want the opposite angle that is along the ground
O=5×tan(173.7/2)=90.854033512
The distance he can see is:
90.85*2~181.7 miles
Now we need to find the distance between lines:
The north south distance between each line is 69 miles
thus the number of degrees he will see will be:
181.7/69
=2 19/30
Answer: y+6=-2(x-4)
Step-by-step explanation:
Point slope form: Y-y1=m(x-x1)
Answer:
B
Step-by-step explanation:
n - 4 = 4.5 - 4 = 0.5
8(n - 4) = 8 *(0.5 ) = 4
6 *n = 6 * 4.5 = 27
8(n - 4) + 6n
8(0.5) + 6*4.5
4 + 27
31
