Solve the simultaneous equations 2x+y=5 5x+3y=12

Bezzdna [24]

Answer:

x=3 and y= -1

Step-by-step explanation:

Step 1: Solve2x+y=5 for y:

2x+y=5

2x+y+−2x=5+−2x(Add -2x to both sides)

y=−2x+5

Step 2: Substitute−2x+5foryin5x+3y=12:

5x+3y=12

5x+3(−2x+5)=12

−x+15=12(Simplify both sides of the equation)

−x+15+−15=12+−15(Add -15 to both sides)

(Divide both sides by -1)

x=3

Step 3: Substitute3forxiny=−2x+5:

y=−2x+5

y=(−2)(3)+5

y=−1(Simplify both sides of the equation)

Answer:

x=3 and y=−1

Lisa's favorite chocolate candies are wrapped in the shape of a triangular prism with shiny gold paper as shown below. If all si

Answer:

Surface Area = 150

Step-by-step explanation:

The surface area of this triangular prism is the sum of area of all the sides.

Surface Area = triangle 1 (with base 8 and height 3) + triangle 2 (same as triangle 1) + lateral surface 1 (with length 7 and width 5 (calculation shown below)) + lateral surface 2 (same as lateral surface 1) + bottom (side not shown with length 7 and width 8)

Triangle 1 area: $\frac{1}{2}bh=\frac{1}{2}(8)(3)=12$
Triangle 2 area: $\frac{1}{2}bh=\frac{1}{2}(8)(3)=12$
Lateral surface 1 (rectangle): $l*w=(7)(5)=35$
Lateral surface 2 (rectangle): $l*w=(7)(5)=35$
Bottom surface (rectangle): $l*w=(7)(8)=56$

Summing all these gives us the total surface area.

Total surface area = $12+12+35+35+56=150$

**** The triangle shown is divided into half by the perpendicular line (3cm) to the base. So the base is divided in half (4 cm and 4 cm).

Now, we have a right triangle with one leg 4 cm and another leg 3 cm. How do we get the hypotenuse? We use Pythagorean Theorem. Which is:

$leg^2+leg^2=hypotenuse^2\\3^2+4^2=hypotenuse^2\\25=hypotenuse^2\\hypotenuse=5$

Hence, the side length of the hypotenuse is 5 [used above in the calculation]
