Solve for x. 4x+7y+5xy=0

Mathematics
1 answer:
Slav-nsk [51]4 years ago
4 0

Answer:

  x = -7y/(4 +5y)

Step-by-step explanation:

You can treat y as though it were a constant. As in any 2-step linear equation, you separate the variable term(s) from the constant term, then divide by the coefficient of the variable.

  4x +5xy = -7y . . . . . subtract 7y

  x(4 +5y) = -7y . . . . . factor out x, so we can see its coefficient

  x = -7y/(4 +5y) . . . . divide by the coefficient of x

martin is making four milkshakes if the recipe calls for 2/3 cup of milk how many cups of milk does he need
Bogdan [553]

The number of cups of milk would be 2 2/3 needed in the four milkshakes.

<h3>What is Ratio?</h3>

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

We have been given that martin is making four milkshakes. The recipe calls for 2/3 cup of milk.

We have to determine the number of cups of milk he needs

Let the number of cups of milk would be x in the four milkshakes.

As per the given situation, we can write the ratio would be as:

1 milkshakes : 2/3 cup of milk = 4 milkshakes : x cup of milk

⇒ 1 / (2/3) = 4/x

Reciprocal the term in the numerator,

⇒ 3/2 = 4/x

Apply the cross-multiplication operation,

⇒ 3x = 8

⇒ x = 8/3

⇒ x = 2 2/3

Thus, the number of cups of milk would be 2 2/3 in the four milkshakes.
