The perimeter of polygon EFGH is 54 inches.
For every 2 inches in polygon ABCD there is 3 inches in poloygon EFGH.
2 fits into 36
18 times
18 times 3 equals 54
Answer:
2/9
Step-by-step explanation:
First, you want to make the 1 and 1/8 an improper fraction. now it should look like 1/4 divided by 9/8. There's this method I learned called "Keep, Change, Flip". Basically, you want to keep the 1/4 the way it is, change the division symbol to a multiplication symbol, and flip the 9/8 so it is now 8/9. The equation now looks like 1/4 x 8/9. The answer should be 8/36, which also equals 2/9. If you have any questions, I'll try my best to answer them. Sorry if this is too long.
Answer:
Step-by-step explanation:
y = -3x - 2
5x + 2y = 15
5x + 2(-3x -2) = 15
5x -6x - 4 = 15
-x - 4 = 15
-x = 19
x = -19
y = -3(-19) - 2
y = 57 - 2
y = 55
(-19, 55)
solution is b
Answer:
Step-by-step explanation:
<em>Inscribed angle is half of the intercepted arc.</em>
- m∠Q = 1/2(mPS + mRS) = 1/2(41° + 137°) = 89°
<em>Opposite angles are supplementary.</em>
<em>Supplementary angles sum to 180°.</em>
- m∠R = 180° - m∠P = 180° - 57° = 123°
- m∠S = 180° - m∠Q = 180° - 89° = 91°
8/1/2=10/n=2*(n-15)/3n*3n=0*3n. Now we do, 2*(n-15)=0, which gives us 2=0. N-15=0. So n=15. Therefore, the answer is n=15.
