X + Y = 4
2x - 3Y = 6
Substitution or Elimination?
Answer:
(x, y) = (18/5, 2/5)Step-by-step explanation:
x + y = 4
x = 4 - y
2x - 3y = 6
Substitution x2x - 3y = 6
2(4 - y) - 3y = 6
8 - 2y - 3y = 6
-5y = 6 - 8
-5y = -2
y = 2/5
Substitution yx = 4 - y
x = 4 - 2/5
x = 20/5 - 2/5
x = 18/5
(x, y) = (18/5, 2/5)PLZ HELP ME I HAVE 5 MORE MINUTES

The surface area of the rectangular prism 158 square feet.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any object is called the surface area.
The rectangular prism will have six faces. The surface area will be calculated as:-
Surface area = 2 ( 3x5) + 2 ( 8x3) + 2(8x5)
Surface area = 30 + 48 + 80 = 158 square meters
Therefore the surface area of the rectangular prism is 158 square feet.

I have a question that says " jada has read 3/5 of a book. She has read 75 pages so far. How many pages are in the whole book?" (I NEED HELP)
Answer and Step-by-step explanation:
To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.
The reciprocal means the the value, but flipped, so [tex]\frac{3}{5}[/tex] will become [tex]\frac{5}{3}[/tex].
Now we do 75 times [tex]\frac{5}{3}[/tex]/
[tex]\frac{75 * 5}{3} \\\\\\\\\frac{375}{3} \\\\\\\\125[/tex]
So, there are 125 total pages in the book.

find the value of x. Round to the nearest degree
Answer:
51 degress
Step-by-step explanation:
sin x = 7/9
x = sin^-1 (7/9)
simply using a calculator.
Answer:
x = 51 degrees
Step-by-step explanation:
(to find x, use sine)
Sine = [tex]\frac{opposite}{hypothenuse}[/tex]
⇒ Sine x = [tex]\frac{7}{9}[/tex]
⇒ [tex]\frac{7}{9}[/tex] = 0.78
⇒ Sine x = 0.78
then calculate what Sine-1 of 0.78 is:
⇒ Sine-1 of 0.78 = 51.26
x = 51.26
Round to the nearest degree:
51.26 ⇒ 51 degrees
The table shows the estimated distances and elevation changes between a base camp and various
locations along a popular mountain trail. The distance traveled along the trail is represented by x, the
elevation is represented by y, and the time from the base camp to each location is represented by t.
1. Use the data points about the distance and elevations of the camps to graph the data points where the
x-coordinate is the total distance traveled from the base camp and the y-coordinate is the elevation. Use
the grid below or include a screenshot of the data plotted from a calculator. (5 points)

Fiona races BMX around a circular dirt course. If the radius of the course is 60 meters, what is the total distance Fiona covers in two laps of the race?
Answer:
753.6 meters
Step-by-step explanation:
Given :
Fiona races a BMX in a dirt course.
The course in circular in shape. The radius of the dirt course is 60 meters.
So the circumference of the dirt course is given by :
[tex]$C = 2 \pi r$[/tex]
= 2 x 3.14 x 60
= 376.8 meters
So the total outer distance of the circular dirt course is 376.8 meters.
Therefore, the total distance that Fiona covers in the two laps of the race is
= 376.8 + 376.8
= 753.6 meters

Principal, P = $ 3000
Duración o período, t = 3 meses
La cantidad final, A, que pagará después de 3 meses:
Usando la fórmula de interés simple:
A = P (1 + rt)
A = 3000 (1 + 0,08 * 3)
A = 3000 (1 + 0,24)
A = 3000 (1,24)
A = $ 3720
