Answer:
220
Step-by-step explanation:
If we take 20 common (as in we can take it out and group the rest) , we can say 20 (15 7/9-4 7/9) which is equal to 20 (11). 20x11 = 220.
Answer:
Step-by-step explanation:
y = 5x + 2.....so we will sub in 5x + 2 for y, back into the other equation
3x = -y + 10
3x = - (5x + 2) + 10
3x = -5x - 2 + 10
3x + 5x = 8
8x = 8
x = 8/8
x = 1
y = 5x + 2
y = 5(1) + 2
y = 5 + 2
y = 7
check it... (1,7)
3x = -y + 10 y = 5x + 2
3(1) = -7 + 10 7 = 5(1) + 2
3 = 3 (correct) 7 = 7 (correct)
so ur solution is : x = 1 and y = 7...or (1,7) <=====

Answer:
20.04 units
Step-by-step explanation:
The diagram shows right triangle ABC. Use the definition of the cosine:
![\cos \angle C=\dfrac{\text{Adjacent leg}}{\text{Hypotenuse}}\\ \\\cos \angle C=\dfrac{BC}{AC}\\ \\\cos 51^{\circ}=\dfrac{BC}{27}\\ \\BC=27\cdot \cos 51^{\circ}\\ \\BC\approx 20.04\ units](https://tex.z-dn.net/?f=%5Ccos%20%5Cangle%20C%3D%5Cdfrac%7B%5Ctext%7BAdjacent%20leg%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D%5C%5C%20%5C%5C%5Ccos%20%5Cangle%20C%3D%5Cdfrac%7BBC%7D%7BAC%7D%5C%5C%20%5C%5C%5Ccos%2051%5E%7B%5Ccirc%7D%3D%5Cdfrac%7BBC%7D%7B27%7D%5C%5C%20%5C%5CBC%3D27%5Ccdot%20%5Ccos%2051%5E%7B%5Ccirc%7D%5C%5C%20%5C%5CBC%5Capprox%2020.04%5C%20units)
