Answer:
no. see below
Step-by-step explanation:
This much of Josh's working is correct:
x^2-6x=7
x^2-6x+9=7+9
(x-3)^2=16
At this point Josh apparently overlooked the fact that he needed to take the square root of both sides of the equation. Had he done that, he would have ...
x -3 = ±4
x = 3+4 . . . or . . . 3 -4
x = 7 or -1
_____
Josh reported values of x that would match ...
x -3 = ±16
He <em>violated the equal sign</em> by taking the square root on the left, and multiplying by ±1 on the right. Doing different operations on the two sides of the equation will mean the value of x is changed to something other than what you're looking for.

Answer:
Less than 25%
Step-by-step explanation:
1189 divided by 967 is 1.229576008...
1.229576008... multiplied by 967 is 1189
This number, 1.229576008..., is a multiplier
To be exact it increases by 22.9576008...%
That is less than 25%
-3x-6=2x-1
5x=-5
x=-1
y=-3(-1)-6
y=3-6
y=-3
hope this helps!
B = amount of students who chose Bulldog
n = amount of students who chose lion
t = amount of students who chose tiger
so.. "t" chose tiger, ok
"<span>Four times as many students chose Bulldog as chose Tiger"
namely, if "t" chose tiger, then 4 times that many chose Bulldog, thus
b = 4t"</span><span>Twice as many students chose Lion as chose Tiger"
namely, if "t" students chose tiger, twice as many chose lion
n = 2tnow, we know a total of 273 students were surveyed, thus
