Y = 5 - 3x....so sub in 5 - 3x for y in the other equation
5x - 4y = -3
5x - 4(5 - 3x) = -3.....distribute the -4 thru the parenthesis
5x - 20 + 12x = -3...add 20 to both sides
5x + 12x = -3 + 20...combine like terms
17x = 17...divide both sides by 17
x = 17/17
x = 1
now sub 1 in for x into either of the original equations to find y
y = 5 - 3x
y = 5 - 3(1)
y = 5 - 3
y = 2
check...
5x - 4y = -3
5(1) - 4(2) = -3
5 - 8 = -3
-3 = -3 (correct)
so ur solution is (1,2)
The answer is 8! or 40,320.
8*7*6*5*4*3*2*1=40,320
h2 + 52 = 102
<span> h2 = 10<span>2 </span>− 52 = 100 − 25 = 75 = 52×3</span>
<span> <span> h = 5</span></span>3 ≈ 8.7
Area A = ½×10×h ≈ ½×10×8.7 ≈ 43 cm<span>2</span>

Answer:
i hope this helps you good luck
Well the answer is going to be less than nine because when u make 9/5 to a mixed number you will 1 4/5. hope that helped
