Step-by-step explanation:
-9(x + 3) + 12 = -3(2x + 5) − 3x
-9x-27+25 = -6x-15-3x
-9x-15 = -9x - 15
same on both sides
so x has infinitely many solutions
The equation has no solutions. Option C is correct.
To figure out which statement is true for equation -9(x + 3) + 12 = -3(2x + 5) − 3x.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
-9(x + 3) + 12 = -3(2x + 5) − 3x.
Simplification,
LHS
= -9(x + 3) + 12
= -9x -21 + 12
= -9x -9
RHS,
= -3(2x + 5) − 3x
= -6x - 15 - 3x
= -9x - 15
Equation RHS and LHS,
-9x - 15 = -9x -9
-15 = -9
Implies, the value of x terminate means the given expression has no solution,
Thus, the equation has no solutions. Option C is correct.

what is the answer for 96+2w = 2(80 - 3w) and whyy???
Answer:
w = 8
Step-by-step explanation:
96 + 2w = 160 - 6w
2w + 6w = 160 - 96

Step-by-step explanation:
96+2w=2(80-3w)
STEP 1 remove perentheses
96+2w=160-6w
STEP 2 take away the ws from one of the sides.
96+8w=160

An object travels along a horizontal straight path at a constant rate. The object travels 1 20 20 1 of the length of the path in 3 4 4 3 second. At that rate, how many seconds does it take the object to travel the entire length of the path?
Answer:
the number of seconds that needed for the overall path length is 15 seconds
Step-by-step explanation:
The computation of the number of seconds that needed for the overall path length is shown below:
The tiny portion is 1 ÷ 20
And, the entire length is 20 ÷ 20
Now if 1 ÷ 20 is travelled in 3 ÷ 4 path so the time needed is
= 20 × 3 ÷ 4
= 15 seconds
Hence, the number of seconds that needed for the overall path length is 15 seconds

A set of speakers costs $22 and songs cost $1.25 each. The sales tax rate is 7.5%. The expression 0.075(22 + 1.25s) can be used to determine the amount of sales tax due on the entire purchase. Expand the expression and round to the nearest hundredth.
Answer:
1.65 + 0.09s
Step-by-step explanation:
Cost of speaker = 22
Cost per song = $1.25
Sales tax = 7.5%
Sales tax due on entire purchase :
0.075(22 + 1.25s)
1.65 + 0.09375s
To the nearest hundredth :
1.65 + 0.09s

Answer:
7 + 4[tex]\sqrt{3}[/tex]
Step-by-step explanation:
note that [tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a
Given
(2 + [tex]\sqrt{3}[/tex] )² = (2 + [tex]\sqrt{3}[/tex] )(2 + [tex]\sqrt{3}[/tex] )
Each term in the second factor is multiplied by each term in the first factor, that is
2(2 + [tex]\sqrt{3}[/tex] ) + [tex]\sqrt{3}[/tex](2 + [tex]\sqrt{3}[/tex] ) ← distribute both parenthesis
= 4 + 2[tex]\sqrt{3}[/tex] + 2[tex]\sqrt{3}[/tex] + 3 ← collect like terms
