Answer:

The correct answer is y = 9

Step-by-step explanation:

It is given that,

12/(4y + 6) = 2/7

<u>To find the value of y</u>

12/(4y + 6) = 2/7

By cross multiplying,

12 * 7 = 2  * (4y + 6 )

84 = 8y + 12

8y + 12 = 84

8y = 84 - 12

8y = 72

y = 72/8 = 9

y = 9

Therefore by solving the given expression we get the value of y = 9

Answer:

y=9 is the answer.

Step-by-step explanation:

The given statement

12 divided by 4y+6 = 2/7

we have to find the value of y.

12/ 4y+6 = 2/7

By cross multipling, we get 12 ×7= 2 × (4y +6)

84 = 8y + 12

8y + 12 = 84

8y = 84 - 12

8y =  72

y = 72/ 8

y = 9 is the answer.

A coffee shop plans to blend a coffee that sells for $12 per pound with coffee that sells for $9 per pound to produce a blend th
zvonat [6]

Answer:

20/3 pounds of coffee that costs $12 per pound  and 40/3 pounds  of coffee that costs $9 per pound are required

Step-by-step explanation:

Let x be the amount of coffee that costs $12 per pound

Cost of x amount of this type coffee = 12x

We are supposed to find How much of each should be used to produce 20 pounds of the new blend that costs $10 per pound

So, Amount of coffee required that costs $9 per pound = 20-x

Cost of (20-x) amount of this type of coffee = 9(20-x)

So, 12x+9(20-x)=10(20)\\12x+180-9x=200\\3x=20\\x=\frac{20}{3}

Amount of coffee that costs $12 per pound required is\frac{20}{3} pounds

Amount of coffee that costs $9 per pound required = 20-x=20-\frac{20}{3}=\frac{40}{3} pounds

Hence 20/3 pounds of coffee that costs $12 per pound  and 40/3 pounds  of coffee that costs $9 per pound are required
