The answer is C.......Sports Stamps = 4 , Holiday Stamps = 2 , Presidents Stamps = 8. He said 4 times as many presidents than holiday. So the number of presidents stamps is the product of the holiday stamps times 4. 4 times 2 is 8. Add them all together
Se a cada 25 minutos ele marca 15 pontos, para saber quantos pontos ele marcou em 200 minutos, basta dividir 200 por 25, que dá 8. Depois multiplicamos 8 por 15, que dá 120. Sendo assim, marcou 120 pontos em 200 minutos.
Resposta: Ele marcou 120 pontos.

Answer:

Step-by-step explanation:
-5x - 10y = 15
<u>-3x + 10y = 25 </u>+
-8x = 40

x = -5
.
Substitute the value of x to one of equations
-5(-5) - 10y = 15
25 - 10y = 15
-10y = 15 - 25
-10y = -10

y = 1
