Answer:
In order for the display to be rectangular the number of quarters is a row have be able to divide evenly into 50. So the number of quarters in a row can be 1,2,5,10,25,50 or 6 ways. Question 3 and 4 are done the same ways as this problem.
Step-by-step explanation:
Answer:
Step-by-step explanation:
These types of equations are called simultaneous equations and the method we can use to solve these type of equations is either Substitution, Elimination and Graphing.
We use substitution here because it is easier.
Equation 1
Equation 2
Lets take equation 1
This is our equation 3 , now put it inside equation 2.
We found the value of y , now to find the value of x insert the value of y in equation 3
Solved ! See the attached image on both the straight line graphs i have attached for better understanding. Where both the lines intersect each other is our value of (x , y) respectively.
Move the triangle, 12 units right and 4 units bottom. Then, rotate it by 180 degrees. Transformation would be done!
Hope this helps!
The tangent of an angle is the ratio of the opposite side to the adjacent side.
... tan(45°) = (height above eye level)/(20 m)
... height above eye level = (20 m)·tan(45°) = (20 m)·1 = 20 m
_____
Eye level is 1.7 m above ground, so the height of the flagpole above ground is
... height of pole = height above eye level + height of eye level
... height of pole = 20 m + 1.7 m = 21.7 m
13x + 7x - 4x = -40
combine like terms o0n the left
16x = -40
divide both sides by 16
x = -5/2 or -2.5
