Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb

weights and y represents the number of 10 lb weights, which equation can be used to find the number of each type of weight Bob has?

The equation would be : 10y + 3x = 50

Hope this helps :)

hello again I need to find an equation to find the long side of the triangle. but this time only the hypotenuse is given. brainl
Hunter-Best [27]

Answer:

The answer to your question is Long = 10.39

Step-by-step explanation:

Data

hypotenuse = 12

long = ?

Process

1.- To find Long, we must use the trigonometric functions sine or cosine.

If we use sine, we use the 60° angle

If we use cosine, we use the 30° angle

a) sin 60 = long / hypotenuse

   Long = hypotenuse x sin 60

   Long = 12 x sin 60

   Long = 10.39

b) cos 30 = Long / hypotenuse

   Long = hypotenuse x cos 30

   Long = 12 x cos 30

  Long = 10.39

Find the quotient and the remainder: (x^2+3x-4)/(x-1)
skelet666 [1.2K]
Evaluate this...
\frac{x^2+3x-4}{x-1}
the x at the bottom cancels out one of the xs at the top so it will be
\frac{x^2+2x-4}{-1}
Now the one cancels out one of the 1s in the -4 so
{x^2+2x-3}

Hope this helps :)

Can someone help me? And possibley tell me how to solve this as well? I'm totally clueless haha
Bumek [7]

Answer:

? = 3

Step-by-step explanation:

To find the value of ?, substitute one of the ordered pairs from the table [except (0, 0)] into the given formula and solve for ?.

Given formula:

\sf y=\boxed{?} \:x

Substitute x = 1 and y = 3 into the formula:

\sf 3=\boxed{?} \:1

To isolate ? divide both sides by 1:

\implies \sf \dfrac{3}{1}=\dfrac{\boxed{?} \:1}{1}

\implies \sf 3=\boxed{?}

Therefore, ? = 3:

\implies \sf y=3x

Check by inputting another value of x from the table into the found formula and comparing the calculated y-value:

\sf x=-2 \implies y=3(-2)=-6 \quad \boxed{\sf correct}

\sf x=3 \implies y=3(3)=9 \quad \boxed{\sf correct}
