Which of the following statements could be a correct step in solving this equation:
12x−7=13(x−12)
A. 12x−7=13x−12
B. 3x−42=2(x−12)
C. 3x−7=2(x−12)
D. 3x−7=2x−12
Answer:
A
Step-by-step explanation:
I think the answer is A because you have to use 13 to multiply what's in the bracket in order to collect like terms but 13 *12 won't give you 12. That's the reason why am confused
A quality-assurance worker wants to systematically sample 120 glass jars each day from a conveyor belt in a factory that puts out 3,600 jars each day. If the worker will select every kth jar, what is the best value of k for the worker to use? Enter a whole number.
Answer:
The best value of k for the worker to use is 30.
Step-by-step explanation:
Sample of 120 jars from a set of 3,600.
If the worker will select every kth jar, what is the best value of k for the worker to use?
The best case would be starting at 0 and ending at 3600, finding 120 values, which means that k is given by the division of 3600 by 120. So
[tex]k = \frac{3600}{120} = \frac{360}{12} = 30[/tex]
The best value of k for the worker to use is 30.

Answer:
y = x^2 + 15x + 56
Step-by-step explanation:
The solutions (where the trinomial = 0) is the factors that will turn the trinomial into 010.
(x + 7)(x + 8) = 0
This means that either -7 will turn the trinomial into 0 or - 8 will.
The trinomial is
x^2 + 8x + 7x + 56 will turn the trinomial to 0.
y = x^2 + 15x + 56 when either - 7 or - 8 is put in for x.
y = (-7)^2 + 15(-7) + 56
y = 49 - 105 + 56
49 + 56 = 105
y = 105 - 105 = 0
y = (-8)^2 - 15(-8) + 56
y = 64 - 120 + 56
y = 120 - 120= 0
No other number will turn the trinomial into 0.
Martin needs 3.25 gallons of paint for his small barn and 1.25 gallons of paint for his shed. he spends $81 on paint, how much does the paint cost per gallon?

1) At a diner, the cost for a specialty waffle and a hashbrown is $9.50. The cost for 2 specialty
waffles and 3 hashbrowns is $20.50. Determine the cost of a waffle and the cost of a hashbrown.
9514 1404 393
Answer:
waffle $8hashbrowns $1.50Step-by-step explanation:
Using w and h for the costs of a waffle and hashbrowns, respectively, we can write the equations for the purchase amounts as ...
w + h = 9.50
2w + 3h = 20.50
Subtracting twice the first equation from the second gives ...
(2w +3h) -2(w +h) = (20.50) -2(9.50)
h = 1.50 . . . . . . simplify
w = 9.50 -h = 8.00 . . . . . find w using the first equation
The cost of a waffle is $8.00; the cost of hashbrowns is $1.50.

Answer:
All those yeye snake me her first
Step-by-step explanation:
Since ∆ABC is congruent to ∆TUV, then:
m<U = m<B
Therefore:
4y - 16 = 3y + 2
Collect like terms
4y - 3y = 16 + 2
y = 18
✔️m<U = 4y - 16
Substitute the value of y:
m<U = 4*18 - 16 = 56°
