Empire star Terrence Howard was paid $1.25 * 105 per episode filmed in season one. If Empire filmed 12 episodes in the first season, how much total salary did Terrence Howard earn?
Answer:
Terrence would have earned $1575 dollars
Step-by-step explanation:
First we multiply 1.25 by 105.
1.25 * 105 = 131.25
Next we multiply 131.25 by 12.
131.25 * 12 = 1575.
So, the answer is 1575.

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 2(m∠Y) − 60°. Find m∠Y.
The value of m∠Y is
I NEED HELP!!! PLS
Answer:
m∠Y=50°
Step-by-step explanation:
So, we know that ∠S+∠Y=90 and that m∠S=2(m∠Y)-60.
If you plug those things into the equation, you get (2[m∠Y]-60)+m∠Y=90.
Then you multiply 2 and m∠Y: 2m∠Y-60+m∠Y=90.
Combine like terms: 3m∠Y-60=90.
Then you add 60 to both sides: 3m∠Y=150
Divide 3 on both sides: 3∠Y=50

2x + y = 9
x = y - 3
Answer:
x=2 and y=5
Step-by-step explanation:
Steps:
I will solve your system by substitution.
x=y−3;2x+y=9
Step: Solve x = y − 3 for x:
Step: Substitute y − 3 for x in 2x + y = 9:
2x+y=9
2(y−3)+y=9
3y−6=9(Simplify both sides of the equation)
3y−6+6=9+6(Add 6 to both sides)
3y=15
3y/3=15/3 (Divide both sides by 3)
y=5
Step: Substitute 5 for y in x = y − 3 :
x=y−3
x=5−3
x=2(Simplify both sides of the equation)
Answer:
x=2 and y=5
Answer:
x = 2 y = 5
Step-by-step explanation:
Since we know that
x = y - 3
We can insert that into the equation above:
2(y-3) + y = 9
After having this equation, we can start by multiplying the numbers/variables in the parenthesis by 2.
2y - 6 + y = 9
Then add the common multiples (2y and y)
That makes:
3y - 6 = 9
We need to get 3y on a side by itself, so to do this, we can add 6 to (-6) and (9)
That makes:
3y = 15
Divide the 3 by 3 and 15 to get the y on its own:
y = 5
Now we need to find x, and to do this we can insert y into the equation:
2x + 5 = 9
Now subtract the 5 from the (5) and (9) and you'll get
2x = 4
Then you divide the 2 on both sides and get
x = 2
You can check your work by inserting x and y into the equation
2(2) + 4 = 9
Sorry for this super long explanation, and hope this helps

suppose potatoes cost $0.99 per pound. complete the function rule c=? to describe the relationships between the total cost c and the number of pounds of potatoes p you buy.
Answer:
c=p*0.99
you gonna multiply the amt of patatoes by the cost of one to get the total like if you were buying 5 you would multiply 5 by 99 to get the total
P = $0.99
C = [tex]P * x[/tex]
[Note: x is how many pounds of potatoes you buy.]
Hope this helped, I'm not too good with relations.

Answer:
26, 64
Step-by-step explanation:
we have :
angle 90°
acute angle x
acute angle 2(x+6)
The sum of the angles in a triangle has to be 180° so
90 +x+2(x+6) = 180
90 +x +2x+12 = 180
3x = 180 -90-12
x= 78/3 = 26°
the other acute angle is 2(26+6) = 64°
Answer:
26, 64
Step-by-step explanation:
We can name the first acute angle x and the second acute angle y. We know that x=2(y+6) but we also need another equation to solve the problem. Since we know that the sum of angles in a triangle is equal to 180 degrees and this is a right triangle, the two acute angles sum will be equal to 90 degrees. That would be our second equation, x+y=90. Now we can just substitute the first equation into the second one: 2(y+6)+y=90 -> 2y+12+y=90 ->3y=78 -> y=26
Now we can substitute y into one of the original equations and solve for x: x+26=90 -> x=64
