Answer:
√x+5=6
2+|3x|=2+3
x/3=2
Step-by-step explanation:
You can remove the first plus sign to give:
-1.3 -4.9 [ because + x - = - ]
and by the same rule you can remove the the second plus sign to give
-1.3 -4.9 - 2.6
That means option b is out because it is positive.
straight away we can see that option D. equals the result, so it is in the running, so now can we eliminate c and a?
we can eliminate a because the minus ign outside the bracket multiplied by -4.9 inside the bracket produces + 4.9, which is not the answer, so that only leaves c.
once again, a plus sign outside the bracket does not produce -4.9 when muliplied by 4.9 inside the bracket inside option c, so we can eliminate option c.

Answer (D)
Answer: Not correct
Step-by-step explanation:
If you plug 3 in for x and 7 in for y and solve you figure out there not equal. -1=-2(3)+7
-2(3)+7=1 because -2x3 is -6 and -6+7 is 1 which means -1=1 which isn’t true
Let x be the unknown number
x×55%=121
x=121÷55%
x=220
So 121 is 55% of 220
