Answer:
9
Step-by-step explanation:
If S is between R and T, then RS+ST = RT
Given the following parameters
RS=2z+6,
ST=4z−3,
RT=5z+12
On substituting
2z+6+4z-3 = 5z+12
Collect like terms
2z+4z-5z = 12+3-6
6z-5z = 15-6
z = 9
Hence the value of z is 9

A pound is approximately 0.45 kilogram. A person weighs 87 kilograms. What is the person's weight, in pounds, when rounded to the nearest
whole number?
ОА
39 lb
OB. 52 lb
OC 193 lb
OD. 180 lb
Answer:
OC 193 lb is correcte!
The person's weight, in pounds, when rounded to the nearest
the whole number is equal to [tex]1.9\times10^{2} pound[/tex]
We have given that, A pound is approximately 0.45 kilogram.
0.45 kg = 1 pound
Thus if 0.45 kg is equal to= 1 pound
87 kg will be equal to [tex]=\frac{1}{0.45} \times 87=1.9 \times 10^2 pound[/tex]

If c – a = b, which of the following statements is true?
A. a + b = c
B. c + b = a
C. a – c = b
D. b – c = a
If c – a = b, then true statement is A. a + b = c
What is commutative property?The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.
Now the given statement is,
c – a = b
adding a to both the the side
c – a + a = b + a
⇒ c = b + a
Using commutative property of addition we get,
a + b = b + a
Therefore, we get
⇒ c = a + b
Thus the true statement is A. a + b = c

2(3x + 6) = 3( x - 9)
Answer:
x= - 13
Step-by-step explanation:
2(3x+6) = 3(x-9)
6x+12 = 3x -27
-3x -3x
3x+12=-27
-12 -12
3x= -39
/3 /3
x= - 13
Answer:
x = -13
Step-by-step explanation:
2(3x + 6) = 3( x - 9)
Distribute
6x +12 = 3x - 27
Subtract 3x from each side
6x-3x+12 = 3x-27-3x
3x+12 = -27
Subtract 12 from each side
3x+12-12 = -27-12
3x = -39
Divide by 3
3x/3 = -39/3
x = -13
6x^2=32x+24 Need help learning factoring please put work so I can understand
Answer:
I do not sorry
Answer:
2 • (x - 6) • (3x + 2)
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
STEP 1 : Equation at the end of step 1
((2•3x2) - 32x) - 24
STEP 2 : Pulling out like terms
Pull out like factors :
6x2 - 32x - 24 = 2 • (3x2 - 16x - 12)
Trying to factor by splitting the middle term
Factoring 3x2 - 16x - 12
The first term is, 3x2 its coefficient is 3 .
The middle term is, -16x its coefficient is -16 .
The last term, "the constant", is -12
Step-1 : Multiply the coefficient of the first term by the constant 3 • -12 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .
-36 + 1 = -35
-18 + 2 = -16 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2
3x2 - 18x + 2x - 12
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (x-6)
Add up the last 2 terms, pulling out common factors :
2 • (x-6)
Step-5 : Add up the four terms of step 4 :
(3x+2) • (x-6)
Which is the desired factorization
Final result : 2 • (x - 6) • (3x + 2)
