Find the ordered pair of x=5y-7 and x+5y=8

Mathematics
1 answer:
zepelin [54]2 years ago
3 0

Answer:

The desired ordered pair is (1/2, 3/2).

Step-by-step explanation:

Let's use the substitution method here to determine either x or y first:

x = 5y - 7 (given).  Then 5y - 7 can be substituted for x in x + 5y = 8:

5y - 7 + 5y = 8.

Combining like terms, we get 10y = 15, so that y = 3/2.

Find x by substituting 3/2 for y in x = 5y - 7:  x = 5(3/2) - 7 = 15/2 - 14/2 = 1/2

The desired ordered pair is (1/2, 3/2).

Point M is on line segment \overline{LN}
MissTica

Considering the relation built the presence of point M on line LN, the numerical length of LN is of 9 units.

<h3>What is the relation from the presence of point M on the line LN?</h3>

Point M splits line LN into two parts, LM and MN, hence the total length is given by:

LN = LM + MN.

From the given data, we have that:

  • LN = 2x - 5.
  • LM = 3.
  • MN = x - 1.

Hence we first solve for x.

LN = LM + MN.

2x - 5 = 3 + x - 1

x = 7.

Hence the total length is:

LN = 2x - 5 = 2 x 7 - 5 = 14 - 5 = 9 units.

Milene é doceira e a seguir está uma representação dos bombons que ela fez no dia. Do total dos bombons que fez 2/3 são de coco.
Paha777 [63]

Answer:

16 bombons de coco

Step-by-step explanation:

A partir da pergunta, somos instruídos a fingir que o número total de bombons (chocolate) que ela fez = 24 bombons

Do total de chocolates que ele fez, 2/3 são de coco.

Portanto, a quantidade que representa os doces de coco é representada como:

2/3 × 24

= 16

Portanto, a quantidade de bombons de coco = 16

2. The radius of a circle is 7cms. The angle subtended by an arc of the circle at centre is 45º. Find the area of sector.​
Vitek1552 [10]

Answer:

19.2cm²

Step-by-step explanation:

Given parameters:

Radius of the circle  = 7cm

Angle subtended by the arc  = 45°

Unknown:

Area of the sector = ?

Solution:

To find the area of the sector, use the expression below;

     Area of sector = \frac{Angle of the arc}{360} x \pi r^{2}

where r is the radius ;

 Insert the parameters and solve;

       Area of sector = \frac{45}{360} x \pi x 7²

       Area of sector = 19.2cm²

elixir [45]

Answer:

Yes, `18 of them wore a different costume

Step-by-step explanation:

49+36=85 which is not 103 children

So then you take 103 and subtract 85 (103-85= 18)

And your answer is 18, so 18 of the children wore a different type of costume.
