It is greater than 1
I hope this helps! I'm also more than happy to elaborate if you want :)
11.
(87+91+86+x)/4=90.
x=96.
13.
50×y > 130.
the lowest number could be 3, because 50×2=120, which is less than 130.
<span>50b 50=11b 95 collect the like terms
50b-11b=95-50
39b=45 divide both sides by 39
b=1.2</span>
Add digit by digit, from the right, just like any number, except that if it adds to 2, then put a zero and carry one (instead of carrying when it adds to 10 or more).
Example: < means carry, decimal equivalent for checking
1011+1111
1 0 1 1 (8+2+1=11)
+ 1 1 1 1 (8+4+2+1=15)
---<---<----<----<----
1 1 0 1 0 (16+8+2=26)
Proceeding similarly,
a. 10101111+11011011 = 110001010 (394)
b. 10010111+11111111 = 110010110 (406)
c. 01110101+10101100 = 10010001 (289)
Answer:
Step-by-step explanation:
-0.25x+1.75x<-1.75+2.5 x
sift terms containing x to right and constant term to left
1.75<2.5 x+0.25x-1.75 x
1.75<2.75x-1.75x
1.75<1.00 x
or 1.75 <x
or x>1.75
