First factor 5x + 50

5x + 50 = 5(x + 10)

(5(x + 10))/(x + 5) x (1)/(x + 10)

Simplify. Note that there is a x + 10 in both numerator and denominator. Cancel them out

(5(x + 10))/(x + 5) x 1/(x + 10)

5/(x + 5) x 1/1

Simplify.

5 x 1 = 5

(x + 5) x 1 = x + 5

5/(x + 5) or (B) is your answer

hope this helps

\dfrac{5x + 50}{x+5} \ \  \centerdot \ \ \dfrac{1}{x +10 }

= \dfrac{5(x + 10)}{x+5} \ \  \centerdot \ \ \dfrac{1}{x +10 }

= \dfrac{5}{x+5}

there are 24 marbles in a bag: 2/16 of the marbles are red, 1/8 of the marbles are blue, 1/4 of the marbles are yellow, 1/3 of t
Roman55 [17]

Answer: 3 red marbles, 3 blue marbles, 6 yellow marbles, 8 black marbles, 4 silver marbles

Step-by-step explanation:

I know these are the correct number of marbles because I set up these numbers as fractions and solved for x.

For examples, 2/16 of the marbles are red. 2/16=x/24

You would do this because we are trying to find the number of marbles that are red out of the 24 marbles.

Next, we would do 24 divided by 16= 1.5 Then 1.5 times 2=3

You would follow this rule for each fraction of marbles in order to find the true number of marbles out of 24.

marysya [2.9K]
Use your knowledge of trig for this. you know the opposite length, 35, and you need to find the hypotenuse. the trig function to use would be SIN.
\sin(60 ) = 35 \div hyp
try to think about which trig functions to use to find the answers for cable 2. if you need more help leave a message.
