Solve for a. Show your work (ALL steps must be shown): 3(a+3)+6=30

Answer:

Multiproperty

Step-by-step explanation:

To solve this problem, we use different properties to arrive at our answer.

  Given expression;

               4(x + 3) = 20;

   First we use the distributive property to expand;

              4x + 12  = 20

       Now use subtraction property by adding (-12) to both sides;

              4x + 12 + (-12)  = 20 + (-12)

              4x  = 8

           you can now divide by 4,

                   x  = 2

System of Linear Equations entered :

 [1]           -2y-3y+z=-6

 [2]           x+y-z=5

 [3]           7x+8y-6z=31

Equations Simplified or Rearranged :

  [1]    -5y + z = -6

  [2]    y - z + x = 5

  [3]    8y - 6z + 7x = 31

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -y + z + 5

// Plug this in for variable  x  in equation [3]

  [3]    8y - 6z + 7•(-y +z +5) = 31

  [3]    y + z = -4

// Solve equation [3] for the variable  z

 [3]    z = -y - 4

// Plug this in for variable  z  in equation [1]

  [1]    -5y + (-y -4) = -6

  [1]    -6y = -2

// Solve equation [1] for the variable  y

  [1]    6y = 2

  [1]    y = 1/3

// By now we know this much :

   y = 1/3

   z = -y-4

   x = -y+z+5

// Use the  y  value to solve for  z

   z = -(1/3)-4 = -13/3

// Use the  y  and  z  values to solve for  x

 x = -(1/3)+(-13/3)+5 = 1/3

Solution :

{y,z,x} = {1/3,-13/3,1/3}

Answer:

Perimeter = A + B + C

Perimeter = 35

A = 2x

B = x+4

C = 13

35 = A + B + C

Step-by-step explanation:

35=2X+X+4+13

SUBTRACT 17 FROM EACH SIDE

18+3X

DIVIDE EACH SIDE BY THREE

X=6

THEREFORE,THE SIDES ARE 12, 10 AND 13

12+10+13=35

Answer:

50,000 + 3,000 + 200 + 70 + 4

Step-by-step explanation:

Expand. Set all non-zero digits by itself:

53,274 = 50,000 + 3,000 + 200 + 70 + 4

Remember to fill in 0 for all digits. They must keep their value.

Answer: There are 16 quarters and 10 dimes.

Step-by-step explanation:

Let x = Number of quarters

y= Number of dimes.

As per given,

x+y = 26  (i)

x= y+6  (ii), substitute this in (i), we get

y+6+y= 26

⇒2y+6=26

⇒ 2y = 26-6=20

⇒ 2y =20

⇒ y =10   [Divide both sides by 2]

Put this in (ii),  x= 10+6 =16

So there are 16 quarters and 10 dimes such that 16 (0.25)+10(0.10)= $5 .

There is only one line that can pass through two points and a plane which has only two dimensions intersects with another plane along a one dimensional line

The figure shows a two lines and two planes

1. [tex]\overset{\longleftrightarrow}{XY}[/tex] shows the symbol of a line, and the capital letters X and Y,

The other names for [tex]\overset{\longleftrightarrow}{XY}[/tex] are;

i) Line XY [tex]\left(\overset{\longleftrightarrow}{XY} \right)[/tex]and ii) Line YX, [tex]\left(\overset{\longleftrightarrow}{YX} \right)[/tex]

Reason:

A line can be named by reversing the order of the letters

2. Opposite rays are two rays that extends in opposite directions but have the same endpoint

Opposite rays are; [tex]\overset{\longrightarrow}{RY}[/tex], and [tex]\overset{\longleftarrow}{RX}[/tex]

Reason:

The rays [tex]\overset{\longrightarrow}{RY}[/tex], and [tex]\overset{\longleftarrow}{RX}[/tex] have a common end point, R, and they move in opposite direction

3. The intersection of two planes is a line;

The intersection of the two planes is the line [tex]\mathbf{\overset{\longleftrightarrow}{RS}}[/tex]

The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.

To calculate 6 divided by 20, you simply perform the division operation. Divide the numerator (6) by the denominator (20):

6 ÷ 20 = 0.3

The result of 6 divided by 20 is 0.3. This means that if you divide 6 into 20 equal parts, each part will be 0.3.

In decimal form, the fraction 6/20 is equivalent to 0.3. Decimal notation is useful when dealing with fractions that don't easily simplify into whole numbers. In this case, the division results in a decimal less than 1, representing a fraction that is less than a whole. The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.

2) [tex]\frac{1}{\sqrt[6]m^{5}}[/tex]

Step-by-step explanation:

As per the laws of indices:

[tex]\frac{x^{a} }{x^{b} } = x^{a - b} \\\\and \\ \\(x^{a})^b = x^{ab}[/tex]

Therefore:

2-(1/3) = 5/3

So m ^(5/3)

5/3 multiplied by -1/2 = -5/6

so m^(-5/6)

Another law of indices:

[tex]x^{\frac{a}{y} } = \sqrt[y]{x^{a} }[/tex]     and when there is something raised to a negative fraction do the reciprocal.

Step-by-step explanation:

By the concept of absolute value, we have:

[tex] | - 9| = 9 \\ \\ | - 15| = 15 \\ \\ |14| - | - 14| \\ = 14 - 14 \\ = 0[/tex]
