2x + 3y = 12 (1st)
5x − y = 13 (2nd) ---> y = 5x - 13
Substitute y = 5x - 13 into (1st) equation
2x + 3(5x - 13) = 12
2x + 15x - 39 = 12
17x - 39 = 12
17x = 51
x = 3
substitute x = 7 into y = 5x - 13
y = 5x - 13
y = 5(3) - 13
y = 15 - 13
y = 2
Answer
solution x = 3 and y = 2
It would be 0.2
Because
1 divided by 5 = 0.2
To check
0.2*5=1
Hope this helps
Have a great day/night
If the width is 2p then the width of both sides is 4p. Subtract that from the total perimeter and you get 16p-4p= 12p. Divide that by two because there are 2 side lengths. So, one side length is 6p.
Answer:
B) 24.84.
Step-by-step explanation:
Its hard to explain but ===>
First do Pythagorean theorem with 2.3 and 5.1.
You will need to do two thing with that answer.
First subtract it from the 10.8. That will be used for later.
Also, multiply it by 2.3 that is for the triangles that are on the sides.
Next you will want to take the number you set aside and multiply it by 2.3.
Finally add and you will have your answer.
The rest of the question is the attached figure
========================================
solution:
========
As show in the attached figure
∠M = ∠R = 54.4°
∠N = ∠T = 71.2°
∠O = 180° - (∠M + ∠N) = 180° - (54.4°+71.2°) = 54.4°
∠S = 180° - (∠R + ∠T) = 180° - (54.4°+71.2°) = 54.4°
∠O = ∠S = 36°
∴ Δ MNO is similar to Δ RTS
So, the correct statement:
The triangles each have two given angle measures and one unknown angle measure.
