#1: 
Solve:
-5/12 x 8/13 = -40/156 
-40/156 can both be divided by 4: 40 ÷ 4 = 10 & 156 ÷ 4 = 39
Your final answer is: Option 2, -10/39

#2
Solve: 
3/8 x (-3/6) you can first simplify 3/6 into 1/2 so-- 3/8 x (-1/2) = -3/16
Your answer is: -3/16

I've solved two of them for you, can you solve the rest on your own? (Reply if you need more answers)

2/3 minus 5/8<br> what’s the answer
Rama09 [41]

Hey there!

  • \frac{2}{3} - \frac{5}{8}
  • Change the "subtract" symbol to a addition symbol
  • \frac{2}{3} + \frac{-5}{8}
  • (-5)(3) = -15
  • 2(8) =16
  • 3(8) = 24
  • \frac{16}{24} + \frac{-15}{24}
  • Add "16 + (-15)" together
  • \frac{16+ (-15)}{24}
  • 16 + (-15) = 1
  • 24= 24
  • Therefore, \boxed{Answer: \frac{1}{24} }

Good luck on  your assignment and enjoy your day!

Katena32 [7]

Answer:

∠ABC= 40°  ∠CBD=60°  ∠EBD=80°

Step-by-step explanation:

Step 1: 2x+3x+4x=180

Step 2: 9x=180

            Combine like terms

Step 3: x=20

            Divide/ Isolate the variable

Step 4: 2(20)=40   3(20)=60    4(20)=80

           Plug the answer back in
