Answer:
AAA (or AA)
Step-by-step explanation:
Prove ΔBEC ~ ΔDEA
(using three angles is unnecessary because you can just use Angle Angle to prove similarity)
First, m∠BCE = m∠EAD because of alternate interior angles.
Then, m∠ADE = m∠CBE because of alternate interior angles.
m∠BEC = m∠AED because of vertical angles
Thus, ΔBEC ~ ΔDEA because of Angle Angle Angle [AAA] (or AA if you only chose to use 2 angles)

Answer:
(2,7)
(1,-3)
(-15,-25)
Step-by-step explanation:
Because both equations are equal to the same thing (y) we can just set them equal to each other and solve for x
4x-1=2x+3
solve for x
4x=2x+4
2x=4
x=2
We know that x=2 and can plug this value in for x into any of the beginning equations
4(2)-1=y
7=y
The answer is (2,7)
2.) We can do the exact same process as question one
x-4= -3x
-4= -4x
x=1
plug this x value in into any of the starting equations
1-4=y
-3=y
The answer is (1,-3)
3.) Same deal as the other two
x-10=2x+5
-x=15
x= -15
Plug this value in for x into any beginning equation
2(-15)+5
-30+5
y= -25

Answer:
p : q = 3 : 2
Step-by-step explanation:
You are given sufficient information to write two relations involving p and q. We presume these will be sufficient to find an answer to the question. We will be able to find p and q. Then we can find their ratio, as the problem asks.
(p-15)/(q-15) = 2/1
(p+30)/(q+30) = 5/4
__
From the first equation, we get ...
p -15 = 2(q -15)
p = 2q -15 . . . . . . . add 15, simplify
From the second equation, we get ...
4(p +30) = 5(q +30)
4p + 120 = 5q + 150
4p = 5q + 30
Using the first equation to substitute for p, we have ...
4(2q -15) = 5q +30
8q -60 = 5q +30 . . . eliminate parentheses
3q = 90 . . . . . . . . . . . add 60-5q to both sides
q = 30 . . . . . . . . . . . . divide by 3
p = 2q -15 = 2(30) -15 = 45
Then the desired ratio is ...
p : q = 45 : 30
p : q = 3 : 2

Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(x−6)+12=20
(4)(x)+(4)(−6)+12=20(Distribute)
4x+−24+12=20
(4x)+(−24+12)=20(Combine Like Terms)
4x+−12=20
4x−12=20

the length of a boat is 10.8 m Boris buys a scale model of the boat the scale of the model is 1 to 18 work out the length of the scale model of the boat give your answer in centimetres
Answers
Answer:
The size of the scale model is 60 centimeters.
Step-by-step explanation:
Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:
1m = 100cm
10.8 m = (10.8 x 100) = 1080 cm
1080/18 = X
60 = X
Therefore, the size of the scale model is 60 centimeters.
