Answer:
first pair yes
second pair no
Step-by-step explanation:
both sides of the first pair are simplified to 10/9
the left side of the second pair = 36/25 while the right side = 34/25
If tossing 1 head is 1/2, then you have to do 1/2^4 which is 1/2 × 1/2 × 1/2 × 1/2 (I imagine it as a tree diagram if that helps). 2^4 is 16, so your answer is b) 1/16. Hope this helps!
Multiple the top equation by 2 and rearrange so that -7 is equal to the others.
-10x+2y=-14
-3x-2y=-12
——————-
-13x=-26
Divide both by -13
x=2
