Solve the following systems by substitution
Paladinen [302]

Answer:

The answer to your question is below

Step-by-step explanation:

Question 1

                x = 5                       Equation l

                2x + y = 10              Equation ll

- Substitute Equation l in equation ll

               2(5) + y = 10

                y = 10 - 10

                y = 0

- Solution  (5, 0)

Question 2

                 x + 16y = 20          Equation l

                 x = 4y                    Equation ll

Substitute equation ll in equation l

                4y + 16y = 20

                        20y = 20

                           y = 20/20

                           y = 1

-Find x

                x = 4(1)

                x = 4

-Solution

                (4, 1)

Question 3

                   2x + 8y = 20            Equation l

                     x = 2                       Equation ll

-Substitute equation ll in equation l

                   2(2) + 8y = 20

                      4 + 8y = 20

                            8y = 20 - 4

                            8y = 16

                              y = 16/8

                              y = 2

- Solution

                   (2, 2)

A cube has an edge length of 4 inches. You double the sides lengths. How many times greater is the volume of the new cube?
N76 [4]
8 times since 4x4x4=64 and 8x8x8=512
so 512/64 equals 8 so it's 8 times greater

Calculate the side lengths a and b to two decimal places. Will give five stars and brainliest to the first answer!!!!! Need help
garri49 [273]

Answer:

Using the Sine Rule , which states that

\frac{a}{Sin A}=\frac{b}{Sin B}=\frac{c}{SinC}

In Δ ABC

∠A +∠B+∠C=180°→→Angle Sum Property of Triangle

72°+85°+∠C=180°

∠C=180° - 157°

∠C= 23°

All the angles are in degrees.

\frac{a}{Sin 72}=\frac{b}{Sin 85}=\frac{6.2}{Sin 23}

Using the table of Sine, Calculating Sine Values

Sin 72°= 0.9510

Sin 85°=0.996

Sin 23°=0.390

\frac{a}{0.951}=\frac{b}{0.996}=\frac{6.2}{0.390}\\\\ a=\frac{6.2 * 0.951}{0.390}= 15.118\\\\ b=\frac{6.2 * 0.996}{0.390}=15.833

Among the five Options,

Option E: a= 15.09 and b=15.81  is approximately true.
