Answer:
B. Dan walked uphill, then downhill.
Step-by-step explanation:
The place that the slope went up is based on the distance from the starting point, so the distance is up then down. I hope this helped and please mark me as brainliest!
If there are x red marbles initially then 1/5 is a probability in it's lowest form cancelled down from:
<span>1/5 = x/5x </span>
<span>so there are 5x total marbles, x red and 4x blue. </span>
<span>Add 5 new red and the new probability is: </span>
<span>(x+5)/(5x+5) = 1/3 </span>
<span>3x+15 = 5x+5 </span>
<span>2x = 10 </span>
<span>originally there were: </span>
<span>x = 5 red </span>
<span>4x = 20 blue </span>
<span>marbles. </span>
<span>*************** </span>
<span>there are now: </span>
<span>x+5 = 10 red </span>
<span>4x = 20 blue </span>
<span>marbles.
hope it helps</span>
Divide 15 with 225 to get 3/5.
Answer:
a) X + X + 1 = 11
Step-by-step explanation:
Em matemática, a soma de consecutivos é expressa matematicamente como:
X + (X + 1) + (X + 2) + (X + 3) .............
Na pergunta acima, somos solicitados a encontrar a expressão algébrica que indica que a soma de DOIS inteiros consecutivos é igual a 11
Portanto, esta expressão algébrica é dada como:
X + (X + 1) = 11
X + X + 1 = 11
Portanto, a opção a) X + X + 1 = 11 é a opção correta
2/3(1+n)=-1/2n
step 1: distribute 2/3 to the parentheses
2/3 + 2/3n = -1/2n
step 2: subtract 2/3n from negative 1/2n
2/3 = -1/6n
step 3: multiply -1/6 and 2/3 by the reciprocal (multiplicative inverse)
-6/1 • 2/3 = n
n= -4
