Find the value of x in
2x + 3x = 20+x​

Answer:

y = -13/16

Step-by-step explanation:

Given:

0.8y+0.25= -0.4

To Find:

Solve for y

Solution:

Multiply both sides by 100

[tex]0.8y\cdot \:100+0.25\cdot \:100=-0.4\cdot \:100[/tex]

Simplify

[tex]80y+25=-40[/tex]

Subtract 25 from both sides

[tex]80y+25-25=-40-25[/tex]

Simplify

[tex]80y=-65[/tex]

Divide both sides by 80

[tex]\frac{80y}{80}=\frac{-65}{80}[/tex]

Simplify

[tex]y=-\frac{13}{16}[/tex]

Thus, y = -13/16

or in decimal form it equal y = -0.8125

Answer:

y = -13/16

Step-by-step explanation:

Given:

0.8y+0.25= -0.4

To Find:

Solve for y

Solve:

Multiply both sides by 100

0.8y ×100  + 0.25 × 100 = -0.4×100

Simplify

80y+25 = -40

      - 25   -25

----------------------

80y = -65

------  ------

80    80

y = -13/16

3. divide it by 2

Answer: 4 yd, 130 in, 10ft

Step-by-step explanation:

So first you turn everything into inches

130 inches is already in inches.

4 yards = 12 ft

1ft = 12 in

12 *12 = 144 in

so 4 yards is 144 inches

10 ft = 12*10

12*10 = 120

so 10ft is 120 inches

144 inches is the greatest and 120 inches is the least.

The answer needs to be in the original form.

The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.

[tex]P=4a[/tex]

Here, (a) is the side of the square.

A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,

[tex]P=4a\\12x +52=4a\\a=\dfrac{12x +52}{4}\\a=\dfrac{4(3x +12)}{4}\\a=3x+12[/tex]

Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

A geometrical series have a constant ratio. The value of r is 4, while the value of a1 is 0.25 and the value of n is 5.

A geometrical series is a series of numbers where the quotient of any two consecutive terms of the series is constant.

The given series is a geometrical series which is given as, 0.25, 1, 4, 16, 64.

Now the value of r is the ratio of any two consecutive terms of the geometrical series therefore, the value of r can be written as,

[tex]r = \dfrac{1}{0.25}=4[/tex]

The a1 of a geometrical series is the first term of the series, therefore, the value of a1 can be written as,

a1 = 0.25

The n is the number of terms in a geometrical series, therefore, the value of n can be written as

n = 5

Hence, the value of r is 4, while the value of a1 is 0.25 and the value of n is 5.

Answer:

what will be the price of the next model= 59,748

Step-by-step explanation:

7748 is 14.9% of 52000

Solution:

What is 14.9% of 52000?

Y is 14.9% of 52000

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 14.9% * 52000

Converting percent to decimal:

p = 14.9%/100 = 0.149

Y = 0.149 * 52000

Y = 7748

To find the price for the next model

7748 + 52000

=> 59,748

An expression has numbers, variables, and mathematical operations. The expression that represents the profit made by the organization is 5x-200.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As it is given that the profit is the difference between the revenue and cost. Therefore, the expression that represents the profit can be written as,

[tex]\rm Profit = Revenue - Cost[/tex]

        [tex]= (3x^2+4x-60)-(3x^2-x+200)\\\\= 3x^2+4x-60-3x^2+x-200\\\\=5x-260[/tex]
