3n + 4 = 7
3n + 4 (-4) = 7 (-4)
3n = 3
3n/3 = 3/3
n = 1
hope this helps
Answer:
-14.000000000000002
Step-by-step explanation:
DETAILED ANSWER:
A change from 50 to 43 represents a negative change (decrease) of -14.000000000000002%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = [(New - Old ) / |Old|] x 100%
Percent change = [(43 - 50) / |50|] x 100 = [(-7) / 50] x 100 = -14.000000000000002 % (decrease)
Where: 50 is the old value and 43 is the new value. In this case we have a negative change (decrease) of -14.000000000000002 percent because the new value is smaller than the old value.
Answer:
x= 15
y= 5
Step-by-step explanation:
it is a reflective opposite side exterior angle or line you are seeing.
The angle on the other side is a vertical angle meaning it is the same. Which leads to show that the measurements are the same as well.
Answer:
the top of the ladder is 27.5ft above the ground.
Step-by-step explanation:
The ladder makes an angle, θ with the ground thus forming a right angle triangle with the wall of the house.
The length of the ladder represents the hypotenuse of the right angle triangle.
The ground distance from the base of the wall to the foot of the ladder represents the adjacent side of the right angle triangle.
Therefore, to determine how high up is the top of the ladder on the wall, x, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
28² = x² + 5²
784 = x² + 25
x² = 784 - 25 = 759
x = √759 = 27.5ft
