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.

2/3 + 3/4 =
Answer:
The answer will be 17/12
Step-by-step explanation:
Hope this Helped
Answer:
1 5/12 or 17/12
Step-by-step explanation:
You can't add them together because they don't have the same denominator so you multiply 2/3 by 4/4 and 3/4 by 3/3. The result is 8/12 and 9/12, you add it together to get 17/12. 17/12 is an improper fraction, if you want you can change it into a mixed fraction which is 1 5/12.

Given the functions, fx) = 6x + 2 and g(x) = x - 7, perform the indicated operation. When applicable, state the domain
restriction
(f/g)(x)
Answer:
Step-by-step explanation:
f(x)/g(x)=(6x+2)/(x-7)
The only restriction upon the domain, possible values of x, is division by zero is undefined. So x cannot equal 7.
So the domain is all real numbers except 7. In interval notation the domain is
x=(-oo, 7),(7, +oo)

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.

Help! Please!!!!!!!!
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°
