Solve for x <br> (19x-18) <br> (7x+1) <br> (10x-9)
ExtremeBDS [4]

Answer:

Step-by-step explanation:

Exterior angle property: Exterior angles equals the sum of remote angles

19x - 18 = 7x + 1 + 10x - 9

19x - 18 = <u>7x + 10x</u> + <u>1 - 9 </u>    {Combine like terms}

19x - 18 = 17x - 8          {Subtract 17x from both sides}

19x - 17x - 18 = -8

        2x - 18 = -8         {Add 18 to both sides}

              2x = -8 + 18

             2x = 10

              x = 10/2

x = 5

La un concurs de matematica se dau 40 de probleme. Pentr fiecare raspuns corect se acorda 7 puncte, iar pentru fiecare raspuns g
Ratling [72]

Answer:

a primit 36 ​​corect ane 4 în mod greșit

Step-by-step explanation:

În această întrebare, ne preocupăm să calculăm numărul de răspunsuri corecte și de răspunsuri greșite pe care elevul le-a dat.

În primul rând, începem prin atribuirea de variabile.

Numărul de răspunsuri corecte să fie x în timp ce numărul de răspunsuri greșite să fie y

Deoarece există 40 de probleme în total, aceasta înseamnă că adăugarea ambelor este egală cu 40 matematic,

x + y = 40. ••• (i)

Acum să trecem la partea complicată. Fiecare răspuns corect = +7. Răspunsul corect total este astfel + 7x Fiecare răspuns greșit este = -5. Răspunsul total greșit este astfel -5y Punct total marcat = 232 Aceasta

înseamnă că; 7x -5y = 232 ••••••••• (ii)

De la i, putem spune y = 40 -x să punem acest lucru în ecuație

ii 7x -5 (40-x) = 232

7x - 200 + 5x = 232

12x = 232 + 200 12x = 432 x = 432/12 x = 36 Deoarece y = 40 - x y = 40 - 36 y = 4

The polynomial 6x²+x–15 has a factor of 2x–3. What is the other factor?
spayn [35]

Step-by-step explanation:

Method 1

Do the factor like

6x

6 \times  ^{2}  +  \times  - 15 \\  = 6 \times  ^{2}  - 9 \times  + 10 \times  - 15 \\  = 3 \times (2 \times  - 3) + 5(2 \times  - 3) \\  = (2 \times  - 3)(3 \times  + 5)

So the other factor is 3x+5

Method 2 We can divise 6x^2+x-15 by 2x-3 and we find the quotient 3x+5

Hope you understand
