Change it into improper fraction to make it easier or just solve it as is.
=3\frac{5}{8}-2\frac{7}{8}
=\frac{29}{8}-\frac{23}{8}
=\frac{6}{8}=\frac{3}{4}            
OR
=3 \frac{5}{8}-2 \frac{7}{8}
divide it to two parts:
3-2=1 and \frac{5}{8}-\frac{7}{8}=\frac{-2}{8}
1\frac{-2}{8}⇒(1×8-2=6)
=\frac{6}{8}=\frac{3}{4}

DOES ANYONE KNOW THE ANSWERS TO THESE PROBLEM, PLZ HELP!
Virty [35]

Answer:

Q.1.

Sum of angles of a triangle = 180°

∠A + ∠B + ∠c = 180

(3x - 9) + (4x + 15) + 90 = 180

3x - 9 + 4x + 15 + 90 = 180

7x + 96 = 180

7x = 84

x = 12

∠A = 3x - 9 = 3(12) - 9 = 36 - 9 = 27°

∠B = 4x + 15 = 4(12) + 15 = 48 + 15 = 63°

∠A = 27°

∠B = 63°

Q.2.

using \ pythagoras \ theorem \\x^2 = 7^2 + (7\sqrt{3} )^{2} = 49  + 49(3) = 196\\x = \sqrt{196}  = 14

sin y = \frac{opposite}{hypotenuse} = \frac{7\sqrt{3} }{14}   = \frac{\sqrt{3} }{2} \\\\y = sin^{-1} (\frac{\sqrt{3} }{2} ) = 60

x = 14

y = 60°

Bonus solve the equation aݔ ଶ + 7x – 4 = 0 for x by using the quadratic formula.
victus00 [196]
   x²  +   7x   -    4    = 0
a = 1,  b = 7, c = -4

x = [-b +/- √(b² - 4ac)]/2a
   = [-7 +/- √(49 + 4)]/2
   = (-7 +/- √53)/2

Do the equation . Pi(r)^2
Radius is 13.
Pi equals technically 3.14
So theoretically ,

3.14(13)^2= 530.929158457
