Answer:

1.2 miles

Step-by-step explanation:

Morning laps = 3.5 laps

Evening laps = 1 lap

Total miles jogged = 5.4 miles

Total laps made = (3. 5 + 1) = 4.5 miles

Number of miles per laps covered :

Total miles jogged / number f lapses hugged around pond.

= 5.4 miles / 4.5

= 1.2 miles

Therefore, number of miles per round around the pond is 1.2 miles

Step-by-step explanation:

Let's simplify step-by-step

4x+3(2x−1)−4x

Distribute:

=4x+(3)(2x)+(3)(−1)+−4x

=4x+6x+−3+−4x

Combine Like Terms:

=4x+6x+−3+−4x

=(4x+6x+−4x)+(−3)

=6x+−3

Answer:

6x - 3

Step-by-step explanation:

4x + 3(2x - 1) - 4x

Distribute, multiply every term inside the parenthesis by the term outside of it,

4x + (3)(2x) + (3)(-1) - 4x

Simplify,

4x + 6x - 3 - 4x

Simplify further, combine like terms,

Answer:

[tex]AC=5[/tex]

Step-by-step explanation:

From the question we are told that:

Dimensions

[tex]AD=4\\BD=6[/tex]

Generally the equation for these similar right triangle is mathematically given by

[tex]\frac{AC}{AB}=\frac{AB}{AD}=\frac{BC}{BD}[/tex]

[tex]\frac{AC}{AB}=\frac{AB}{AD}[/tex]

Where

[tex]AD=x[/tex]

[tex]AC=x+4[/tex]

Therefore

[tex]AB^2=x(x+4)[/tex]

Generally the Pythagoras equation for [tex]\triangle[/tex]ADB is mathematically given by

[tex]AB^2=BD^2+AD^2[/tex]

[tex]x(x+4)=4+x^2[/tex]

[tex]x(x+4)-(4+x^2)=0[/tex]

[tex]x^2+4x)-(4+x^2)=0[/tex]

[tex]4x-4=0[/tex]

[tex]x=1[/tex]

Therefore

[tex]AC=x+4[/tex]

[tex]AC=1+4[/tex]

[tex]AC=5[/tex]

Answer: 12

Step-by-step explanation:

Answer:

the system : 9x-3y =21

                   2x+3y = 12

Step-by-step explanation:

hello :

an system of equations has the same solutions as the system below

 the  system  3x-y=7

                     2x+3y=12

for exempl  :  3×(3x-y)=3×7

                     2x+3y)=12

means :

9x-3y =21

2x+3y = 12

6x - 2y = 14, 2x + 3y - 6 = 6 has the same solution as the system of equations 3x - y = 7, 2x + 3y = 12

A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.

Given system of equations

3x - y = 7........................(1)

2x + 3y = 12...................(2)

Multiply equation 1 with 2

2(3x - y) = 2 × 7

6x - 2y = 14

Subtract 6 from equation 2

2x + 3y - 6 = 12 - 6

2x + 3y - 6 = 6

So, 6x - 2y = 14, 2x + 3y - 6 = 6 has the same solution as 3x - y = 7,

2x + 3y = 12

Answer:

3 m

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 5 = 8 parts

Divide the length by 8 to find the value of one part of the rope

24 m ÷ 8 = 3 m ← value of 1 part of the ratio

Thus the shortest piece is 3 m

The required length of the shortest piece is 3 meters.

Given that,
A rope 24m long is divided into three pieces in a ratio of 1:2:5. The length of the shortest piece in meters is​ to be determined.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
let the required proportion is equal to x,
then,

x + 2x + 5x = 24
8x = 24
x = 3

Now the lengths
x = 3 meter
2x = 6 meter
5x = 15 meter

Thus, the required length of the shortest piece is 3 meters.

Answer:

x = 20

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the angles in the triangle and equate to 180

2x + x + 30 + 90 = 180

3x + 120 = 180 ( subtract 120 from both sides )

3x = 60 ( divide both sides by 3 )

x = 20

Its C

Step-by-step explanation:

Answer:

[tex]\left[\begin{array}{ccc}1&2\\6&7\end{array}\right]\cdot \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}0\\-10\end{array}\right][/tex]

Step-by-step explanation:

The system of equation in matrix form is defined by following vector formula:

[tex]\vec A \cdot \vec x = \vec b[/tex] (1)

Where:

[tex]\vec A[/tex] - Matrix of coefficients.

[tex]\vec x[/tex] - Column vector of variables.

[tex]\vec b[/tex] - Column vector of results.

If we know that [tex]x + 2\cdot y = 0[/tex] and [tex]6\cdot x + 7\cdot y = -10[/tex], then the system of equations in matrix form is:

[tex]\vec A = \left[\begin{array}{ccc}1&2\\6&7\end{array}\right][/tex], [tex]\vec x = \left[\begin{array}{ccc}x\\y\end{array}\right][/tex], [tex]\vec b = \left[\begin{array}{ccc}0\\-10\end{array}\right][/tex]

Then,

[tex]\left[\begin{array}{ccc}1&2\\6&7\end{array}\right]\cdot \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}0\\-10\end{array}\right][/tex]

Answer:

B) 16x² - 40x + 25

1) Use square differences: (a - b)² = a² - 2ab + b².

[tex](4x)^{2} - 2 \times 4x \times 5 + {5}^{2} [/tex]

2)Use Multiplication Distributive Property: (xy)^a = x^a y^a.

[tex] {4}^{2} {x}^{2} - 2 \times 4x \times 5 + {5}^{2} [/tex]

[tex]16 {x}^{2} - 2 \times 4x \times 5 + {5}^{2} [/tex]

4) Simplify 5² to 25.

[tex]16 {x}^{2} - 2 \times 4x \times 5 + 25[/tex]
