What is the answer for 3r=10+5 when r=10

Mathematics
1 answer:
katen-ka-za [31]2 years ago
6 0

Answer:

Step-by-step explanation:

What is the VALUE OF 3r=10+5 when r=10?

substitute 10 for r in 3r=10+5.  We get:

3(10) = 10 + 5, or 30 = 15.  This equation is FALSE when r = 10.

You could solve the equation for r, however:

3r=10+5 becomes 3r = 15, and so r = 5.  5 is a solution; 10 is not a solution.

Answer:

  • <u>First choice, 984 cm²</u>

Explanation:

The plastic pencil case has form of a triangular prism.

This triangular prism has five faces:

  • Top and bottom faces: two congruent triangles with a 10 cm base and 12 cm height.

  • Lateral faces: two congruent rectangles with a 24 cm length and 13 cm widht, and one rectangle with 24 cm length and 10 cm widht.

<u>Surface area:</u>

  • <u>Top and bottom triangles</u>:

        area = (1/2) base × height

         area of one triangle = 10 cm × 12 cm × (1/2) = 60 cm²

          area of the two triangles = 2 × 60 cm² = 120 cm²

  • <u>Lateral rectangles:</u>

        area of a rectangle = length × width

         area of the trhee triangles = 24 cm × 10 cm + 2 × 24 cm × 13 cm = 240 cm² + 624 cm² = 864 cm².

  • <u>Total area: </u>120 cm² + 864 cm² = 984 cm²

Answer: first choice, 984 cm²

X=16-4y. systems of equations 3x+4y=8<br> substitution
alina1380 [7]

Answer:

x=-4  y=5

Step-by-step explanation:

Rewrite equations:

x=−4y+16;3x+4y=8

Step: Solvex=−4y+16for x:

x=−4y+16

Step: Substitute−4y+16forxin3x+4y=8:

3x+4y=8

3(−4y+16)+4y=8

−8y+48=8(Simplify both sides of the equation)

−8y+48+−48=8+−48(Add -48 to both sides)

−8y=−40

−8y

−8

=

−40

−8

(Divide both sides by -8)

y=5

Step: Substitute5foryinx=−4y+16:

x=−4y+16

x=(−4)(5)+16

x=−4(Simplify both sides of the equation)

Answer:

x=−4 and y=5
