Answer:
x>2 or x<-10
Step-by-step explanation:
9|x +4|>54
Divide each side by 9
9/9|x +4|>54/9
|x +4|>6
There are two solutions, one positive and one negative
x+4 >6 or x+4 < -6
Subtract 4 from each side
x+4-4 >6-4 or x+4-4 < -6-4
x>2 or x<-10
Answer:
B
Step-by-step explanation:
To solve for x, we have to get x by itself. To do this, perform the opposite of what is being done to the equation.
5x+14=k
First, subtract 14 from both sides, because 14 is being added on to 5x. Subtraction is the opposite of addition.
5x+14-14=k-14
5x=k-14
Now, divide both sides by 5, because 5 and x are being multiplied. Division is the opposite of multiplication.
5x/5=k-14/5
x=k-14/5
So, the correct answer is choice B
30 percent decrease
Step-by-step explanation:
looking at this i know its a percent decrease
so how do we find percent decrease ?
first we subtract the first value 39.39 & the final value 27.57
39.39-27.57 = 11.82
then we divide 11.82 by the first value
like this 11.82÷39.39 = 0.3000
then we multiply what we got by 100
0.3000×100= 30 percent
the way that most people mess up is when they divide sometimes they might do 39.39 divided by 11.82 instead of 11.82÷39.39.
It looks like a slide because it looks to be shifted not flipped or changed in other way.
Answer:
the first one is 192 and the second is 396 the third is 216 the fourth is soapy suds
Step-by-step explanation:
the first you just do 4x6x8
the second you just do 9x8x11 and then divide by 2
the third you just multiply 9x6x4 or you could do 3x4x9 and multiply that by 2
the fourth is soapy suds bc it has a larger volume of 1248 while clean and bright only has a volume of 936
