Answer:
62
Step-by-step explanation:
Since we know what each value of the three variables are, you can substitute each variable in the expression to get:
[tex]8^{2} -12(\frac{1}{2})[/tex] ÷ 3
Simplify to get:
64 - 6 ÷ 3
Solve the rest:
64 - 2 → 62
Answer: 62
Hope this helps! :)

Raisins (x) that sell for $1.60 per pound are mixed with chocolate chips (y) that sell for $2.45 per pound to make 17 pounds of a mixture. The mixture sells for $2.00 per pound. Which system of linear equations can be used to find the amount of each ingredient in the mixture?
A) xy = 17
1.60x + 2.45y = 34
B) x + y = 17
1.60x + 2.45y = 34
C) x + y = 17
1.60x + 2.45y = 17
D) x + y = 17
1.60x − 2.45y = 34
Answer: B) x + y = 17
1.60x + 2.45y = 34
Step-by-step explanation:
Cost of x = $1.60 per pound
Cost of y = $2.45 per pound
Total pounds of x and y = 17
Cost per pound of mixture = $2
Total number of pounds of the mixture :
x + y = 17
Since the cost per pound of the mixture = 2
Hence ;
(Cost of x * number of pounds of x) + (Cost of y * number of pounds of y)
(1.60 * x) + (2.45 * y) = (cost per pound of mixture * total number of pounds of the mixture)
1.60x + 2.45y = 2 * 17
1.60x + 2.45y = 34

Carissa earns $450 per week for a 40 hour work week plus $16.83 per hour for each hour of overtime after 40 hours. Write an equation that would be used to determine her weekly wages where, W, is her wages and, V, is the number of overtime hours worked.
Answer:
W = 450 + 16.83V
Step-by-step explanation:
For 40 hours Carissa
earning = $450
earning for 1 hour of over time = $16.83
multiplying both side by V
earning for v hour of over time = $16.83*V = $16.83V
weekly wage(W) = earning for 40 hours + earning for V hour of over time
W = 450 + 16.83V
Thus equation will be as given below for weekly earning

Gavin works as a salesperson at an electronics store and sells phones and
phone accessories. Gavin earns a $12 commission for every phone he sells
and a $3.50 commission for every accessory he sells. On a given day, Gavin
made a total of $135 in commission and sold 12 more accessories than
phones. Determine the number of phones sold and the number of accessories
sold.
Answer: Hence, there are 6 phones and 18 accessories sold.
Since we have given that
Let number of phones sold be 'x'
Let number of accessories sold be 'y'.
Commission for every phone = $12
Commission for every accessory = $3.50
Total commission = $135
And Difference between accessories and phones sold = 12
According to question, we get that
Using both the equations, we get that
x=6 and y = 18

If the scale factor of Figure A to Figure B is 7:2, find the perimeter of Figure A.
Answer:
122.5 units
Step-by-step explanation:
The proportion would be between the perimeters and the given ratio:
7/2 = p/p
Where P is the perimeter of the bigger figure and p is the perimeter of the smaller figure.
Remember that the perimeter is the sum of all sides, using all given values and solving for P, we have
7/2=P/9+5+9+12
7/2=P/35
7(35)/2=P
P=245/2=122.5
Therefore, the perimeter of Figure A is 122.5 units.
