Answer:
x = 5/39
, y = 539/39
Step-by-step explanation:
Solve the following system:
{y - 2.5 x = 13.5
12.25 x - y = -12.25
In the first equation, look to solve for y:
{y - 2.5 x = 13.5
12.25 x - y = -12.25
y - 2.5 x = y - (5 x)/2 and 13.5 = 27/2:
y - (5 x)/2 = 27/2
Add (5 x)/2 to both sides:
{y = 1/2 (5 x + 27)
12.25 x - y = -12.25
Substitute y = 1/2 (5 x + 27) into the second equation:
{y = 1/2 (5 x + 27)
1/2 (-5 x - 27) + 12.25 x = -12.25
(-5 x - 27)/2 + 12.25 x = 12.25 x + (-(5 x)/2 - 27/2) = 9.75 x - 27/2:
{y = 1/2 (5 x + 27)
9.75 x - 27/2 = -12.25
In the second equation, look to solve for x:
{y = 1/2 (5 x + 27)
9.75 x - 27/2 = -12.25
9.75 x - 27/2 = (39 x)/4 - 27/2 and -12.25 = -49/4:
(39 x)/4 - 27/2 = -49/4
Add 27/2 to both sides:
{y = 1/2 (5 x + 27)
(39 x)/4 = 5/4
Multiply both sides by 4/39:
{y = 1/2 (5 x + 27)
x = 5/39
Substitute x = 5/39 into the first equation:
{y = 539/39
x = 5/39

Answer: The Answer is 7
Step-by-step explanation:
Fourteent percent are coated chocolated were yellow out of 50.
So you need to multiple 0.14 (14%) by the 50 candies on the bag that way you get 7.
Answer:
Step-by-step explanation:
Use SOH-CAH-TOA
Sin(25º) = x/10 (x being the height of the triangle)
x= Sin (25º) (10)
x = 4.23
Now for the base:
Cos (25º) = x/10
x = cos(25º)(10)
x = 9.06
Now solve for the area using 1/2bh
19.2 in^2
The answer you have selected is correct :)
In this sequence, a₁ equals -1.
The difference between each term is +3, so the coefficient for n will be 3.
In the sequence, a₂ equals 2. The following equation will fit this sequence, and will be your answer:
Proof:
