Irina,Teodor și Andrei au participat la un concurs.Irina și Teodor au obținut împreună 559 de puncte,Teodor și Andrei au împreun
andreev551 [17]

Answer:

Numărul de puncte:

Irina a obținut = x = 245 puncte

Teodor a obținut = y = 314 puncte

Andrei a obținut = z = 286 puncte

Step-by-step explanation:

Să ne reprezentăm

Numărul de puncte:

Irina a primit = x

Teodor got = y

Andrei got = Z

Irina, Teodor și Andrei au participat la un concurs.

Irina și Teodor au obținut 559 de puncte împreună

x + y = 559 ....... Ecuația 1

Teodor și Andrei au obținut 600 de puncte împreună

y + z = 600 ...... Ecuația 2

y = 600 - z

Irina și Andrei 531 puncte.

x + z = 531 ....... Ecuația 3

Substitui

600- z pentru y în ecuația 1

x + 600 - z = 559

Colectează ca termeni

x - z = 559 - 600

x - z = -41 ..... Ecuația 4

Combinând ecuația 3 și 4 împreună

x + z = 531 ....... Ecuația 3

x - z = -41 ..... Ecuația 4

Am face și ecuația 3 și 4 împreună pentru a elimina z

2x = 490

x = 490/2

x = 245 puncte

Rezolvarea pentru z folosind ecuația 4

x - z = -41 ..... Ecuația 4

245 - z = -41

Colectează ca termeni

z = 245 + 41

z = 286 puncte

Rezolvarea pentru y

y = 600 - z

y = 600 - 286

y = 314 puncte

Prin urmare,

Numărul de puncte:

Irina a obținut = x = 245 puncte

Teodor a obținut = y = 314 puncte

Andrei a obținut = z = 286 puncte

You have a summer job running errands for a local business. You earn 12.25 per day, plus $1.50 for each errand. Write and solve
Stella [2.4K]

Hello!

You have already earned 12.25 dollars. So now, you need to earn $31.75. If each errand is $1.50, you can divide $31.75 by $1.50. You would get roughly 21.17. Since you can not do 21 errands and .17 of an errand, you would need to do about 22 errands to get the money you need, which is the $31.75. 1.50 times 22 is equal to thirty-three, so youd be getting about a dollar and 25 cents more than what you need. We can had 33 (what we earn from our 22 errands) to 12.25, which is what we already have, and we get 45.25! So you can earn more money than you need to earn.

Hope this helps, have an awesome day!

Which expression is equivalent to x2(3x3−2x)−(−7x3+2) ? 3x5+5x3−2 3x5−9x3+2 3x5+7x3−2x+2 3x6+7x3−2x2−2
erik [133]

Answer:

The equivalent expression is 3x^5-9x^3-2

Step-by-step explanation:

To find the equivalent expression, we need to

open up the brackets;

Thus;

x^2(3x^3 -2x) - (7x^3 + 2)

= 3x^5 -2x^3 -7x^3 -2

= 3x^5 -9x^3-2
