Answer:

31/35

Step-by-step explanation:

3/5 + 2/7 = (3 × 7) / (5 × 7)  + (2 × 5) / (7 × 5)

= 21/35 + 10/35

= 31/35.

Answer:

Answer:

Sum of ages is 35

Since there are two persons and it says four years from now, each year 2 more years will be added on to the 35 so year 1: 2years Year 2:4years Year 3:6years Year 4 : 8years

35+8= 43

Remember that Melanie will be 5 years older ( which she should have already been)

so 43+5= 48 ( Melanie's age)

and 48-5 = 43 ( Her brother's age)

Answer:

The zeros are x =5, -7/2

Step-by-step explanation:

To find the zeros, set the expression equal to zero

(x-5)(2x+7) =0

Using the zero product property

(x-5)=0     (2x+7)=0

Solve each equation

x=5               2x = -7

x=5                  x = -7/2

The zeros are x =5, -7/2

Answer:

5, -7/2

Step-by-step explanation:

[tex]x - 5 = 0 = 5\\\\2x + 7 = 0\\2x + -7 = 0\\\frac{2x}{2} = \frac{-7}{2}\\ x = \frac{-7}{2}\\x = -\frac{7}{2}[/tex]

Thus,

x = 5

x = -7/2

1) The solution to the given quadratic equation is; x = ¹/₂(3 ± 3√2)

2) The solution to the given quadratic equation is; x = 5/6 or -2

1)  (2x - 3)² = 18

To fid the value of x, we can solve by first taking the square root of both sides to get;

√(2x - 3)² = ±√18

Add 3 to both sides using addition property of equality to get;

2x - 3 = ±3√2

2x = 3 ± 3√2

x = ¹/₂(3 ± 3√2)

2) 2(5x + 2)² = 64

To fid the value of x, we can solve by first  dividing both sides to get;

(5x + 2)² = 32

Take square root of both sides to get;

(5x + 2) = ±8

Subtract 2 from both sides using subtraction property of equality to get;

5x + 2 = ±8

5x = ±8 - 2

5x = 6 or 5x = -10

x = 5/6 or -2

The dimensions of the rectangle are:

width = 10 units

length = 17 units

We are given to find the dimensions of a rectangle with an area equal to the parallelogram with vertices (6, 21), (14, 15), (6, 0), and (-2, 6).

If we have two points with coordinates as (a, b) and (c, d) The distance is given by the formula: √[(c - a )² + (d - b)²]

Now, of the coordinates are labelled as;

A(6, 21), B(14, 15), C(-2,6),  (6,0)

Thus;

AB = √(14 - 6)² + (15 - 21)² = √100 = 10 = CD

AC = √(-2 - 6)² + (6 - 21)² = 64 + 225 = √289 = 17 = BD

The standard deviation of the distribution of means is generally smaller than the standard deviation of the population of individuals.

The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.

The population of individuals is always smaller than the entire population, therefore the possibilities for variances will be lower with the sample than with the population. The higher the population, the greater the chances for deviation from the mean.

Therefore, the standard deviation of the distribution of means is generally smaller than the standard deviation of the population of individuals.

I'm assuming the equation is

Let me know if the equation is different so I can update the solution.

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

Fractions are a pain to deal with, so it's best to eliminate them whenever we can. In equations like this, we can multiply both sides by 4 since this is the LCD (which stands for "lowest common denominator").

If we multiply both sides by 4, then all the denominators of 4 will cancel.

We'll have these steps:

[tex]\frac{3}{4}y - \frac{2}{4}y+7 = \frac{2}{4}y-1\\\\4\left(\frac{3}{4}y - \frac{2}{4}y+7\right) = 4\left(\frac{2}{4}y-1\right)\\\\3y - 2y + 28 = 2y - 4 \ \ \text{ ... denominators cancel after distributing}\\\\y + 28 = 2y - 4\\\\y- 2y =- 4-28\\\\-y = -32\\\\y = \frac{-32}{-1}\\\\y = 32\\\\[/tex]

Answer:

[tex]y=32[/tex]

Step-by-step explanation:

Given the following question:

[tex]\frac{3}{4}y-\frac{2}{4}y+7=\frac{2}{4}y-1[/tex]
[tex]\frac{3}{4}y-\frac{2}{4}y+7-7=\frac{2}{4}y-1-7[/tex]

Given that Point E is the midpoint of line segment YT, the numerical value of x is 2.

A midpoint is simply a point that divides a segment into two equal halves.

Given the data in the question;

Point E is the midpoint of line segment YT, YT is divided into two equal halves. Hence, Two times Line segment YE equals to YT.

2( Line segment YE ) = Line segment YT

Plug in the given values and solve for x.

2( Line segment YE ) = Line segment YT

2( 3x + 1 ) = 14

Expand using distributive property

2 × 3x + 2 × 1 = 14

6x + 2 = 14

Collect like terms

6x = 14 - 2

6x = 12

6x/6 = 12/6

x = 12/6

x = 2

Step-by-step explanation:

The coordinates of the other endpoint U are found to be (Xu, Yu) = (10, 5).

The coordinates are a pair of numbers which characterize the exact location of a point on a cartesian plane through using horizontal and vertical lines.

Now, as per the question.

To find the coordinates of U, use the midpoint formula with the coordinates of points u and v (Xv, Yv) and (Xm, Ym) respectively.

Let's refer to them as (Xu, Yu)

Midpoint formula {(Xv + Xu)/2, (Yv + Yu)/2)}

Fill in the recognized coordinates as needed.

Point V at (10, 7) =  (Xv, Yv)

Midpoint, point M at (10, 6) = (Xm, Ym)

For the x coordinates;

(10 + Xu)/2 = 10

Xu = 10.

Similarly for the y coordinate;

(7 + Yu)/2 = 6

7 + Yu = 12

Yu = 5

We can test this by plugging U's coordinates into the midpoint formula.

(10 + 10)/2 = 20/2 = 10

(5 + 7)/2 = 12/2 = 6

Therefore, the coordinates of the are (Xu, Yu) = (10, 5).

We get the surface area as 202 inches² and volume as 168 inches³.

The surface area of a cuboid is given by:

Surface area = 2xy + 2xz + 2yz

Here length = x = 7 inches

Breadth = y = 3 inches

Height = z = 8 inches.

Substituting the values in the formula, we get that:

Surface area = A = 2(7)(3) + 2(7)(8) + 2(3)(8) inches²

A = 42 + 112 + 48 inches²

A = 42 + 160 inches²

Start with angle PQR that we will bisect.

1.  Place the compasses' point on the angle's vertex Q.

2.  Adjust the compasses to a medium wide setting. The exact width is not important.

3.  Without changing the compasses' width, draw an arc across each leg of the angle.

4.  The compasses' width can be changed here if desired. Recommended: leave it the same.

5.  Place the compasses on the point where one arc crosses a leg and draw an arc in the interior of the angle.

6.  Without changing the compasses setting repeat for the other leg so that the two arcs cross.

7.  Using a straightedge or ruler, draw a line from the vertex to the point where the arcs cross.

8. This is the bisector of the angle ∠PQR.

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

It is given that:

A = $25,600
