B. the sum of
1/5
of m and
2/5
of m

Answer K= 20/x

Step-by-step explanation:

The value of k in the given linear equation is 20.

A linear equation is an equation where the variable (or variables) has the highest power of one.

Given,

310 - (30 × 7)=5 × k

⇒ 310 - 210 = 5k

⇒ 5k = 100

⇒ k = 100/5 = 20

Answer:

[tex]infinitely \: many \: solution[/tex]

Step-by-step explanation:

simplify 2 - 10 to -8.

[tex] - 8 \leqslant 22[/tex]

Since -8 ≤ 22 is always true, there are infinitely many solutions.

hence, there are infinitely many solutions for this equation.

Answer:

13/18 which is 72.22% chance of NOT getting a red sock

Step-by-step explanation:

As there are 18 total socks, and 13 of them are NOT red, you have a 13 out of 18 chance, or 13/18, or NOT drawing a red sock. This can be converted to the decimal, 0.7222, or percentage of 0.7222 * 100 = 72.22%

Answer:

216 in2

Step-by-step explanation:

the area of the rectangle is

20(12)=240

area of the triangle is

4(6)= 24

so now we subtract, 240-24= 216 in2

Answer:

Billy purchased 9 types of one type and 16 types of another spinner.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

Billy bought 25 spinners.

Let x and y are the type of spinners.

Then, x + y = 25  {equation 1}

Some were $10 and some were $15.

10x + 15y = 295  

Simplifying,

2x + 3y = 59    {equation 2}

Multiplying 2 to the equation 1 and subtraction the equation 2,

-y = -9

y = 9

And x = 16

Therefore, each type of spinner is 9 and 16.

Answer:

256 is the right ama as 4/5*320 is 256

Answer:

The mistake that Andy made was on step 2 when he multiplied only the variables by 12.

Step-by-step explanation:

When you're solving an equation and are multiplying one side by a number, you need to multiply the other side by that number as well to keep the equation true. Since Andy multiplied only the variables and not the constants on each side of the equation, that means the equation would no longer be valid, and solving it would provide a wrong answer.

Answer:

tan R = 45/28 where ∡R=58.11° and tan S = 28/45 where ∡S=38.48°

Step-by-step explanation:

The tangent of a right triangle's angle is equal to the ratio between the triangle's opposite side to its adjacent side.

tan R = 45/28

R = tan^-1(45/28)

R = 58.11°

tan S = 28/45

S = tan^-1(28/45)

S = 38.48°

Answer:

a) r = √V/6π

b) r = 8 inches

Step-by-step explanation:

a) The volume V​ (in cubic feet) of a right cylinder with a height of 6 feet and radius r (in feet) is given by V=6πr2​ . Solve the formula for r​ .

Solving for r means making r the subject of the formula

= V=6πr²

Divide both side by 6π

V/6π = 6πr²/6π

r² = V/6π

r = √V/6π

b) Then find the radius of the cylinder when the volume is 1206 cubic feet. Round your answer to the whole number.

r = √V/6π

V = 1206 ft³

r = √1206/6π

r = √(63.98028712294193)

r = 7.9987678503 inches

Approximately r = 8 inches
