Subtract 43 from 20 raised to the 7th power; then multiply by 3.

viktelen [127]

Hi there! :)

Answer:

Subtract 43 from 20 raised to the 7th power; then multiply by 3. The answer is: 3,839,999,871

Step-by-step explanation:

"Subtract" means to take away a number from another.

" 20 raised to the 7th power" is the same thing as 20 exponent 7: $20^{7}$

SO, you want to take away 43 from $20^{7}$ and then multiply the answer by 3:

( $20^{7}$ - 43) × 3

$20^{7} =$ 1,280,000,000

(1,280,000,000 - 43) × 3

1,280,000,000 - 43 = 1,279,999,957

1,279,999,957 × 3

1,279,999,957 × 3 = 3,839,999,871

There you go! I really hope this helped, if there's anything just let me know! :)

I'm completely lost

Let x be the number of racing bikes, and let y be the number of mountain bikes.
1) 140x + 110y = 26150
2) 180x + 120y = 31800
Solve for one of the variables and plug that in to the other equation:
From equation 1: 140x = 26150 - 110y
x = (26150-110y)/140
Plug this into equation 2:
180((26150-110y)/140) = 31800
Solve for y, and find that y = 85 (the number of mountain bikes).
Plug that y into either equation to find x:
140x + 110(85) = 26150
x = 120 (the number of racing bikes).
So the answer is: 120 racing bikes and 85 mountain bikes.

Trei copii au impreuna 45 de lei .

Ainat [17]

Answer:

Primul copil are 6 lei, al doilea are 12 lei, al treilea are 27 de lei.

Step-by-step explanation:

Lăsați suma primului copil să fie x.

Lăsați suma al doilea copil să fie y.

Lăsați suma al treilea copil să fie z.

Trei dintre ei au 45 de lei în total.

Aceasta înseamnă că:

x + y + z = 45 ________(1)

Al doilea are de două ori valoarea primului:

y = 2x

Al treilea are cu 15 lei mai mult decât al doilea:

z = 15 + y

=> z = 15 + 2x

Puneți valoarea y și z în (1):

x + 2x + 15 + 2x = 45

5x = 45 - 15 = 30

x = 30 / 5 = 6 lei

=> y = 2 * 6 = 12 lei

=> z = 15 + 12 = 27 lei

Primul copil are 6 lei, al doilea are 12 lei, al treilea are 27 de lei.
