A grocery store bought some mangoes at a rate of 5 for a dollar. They were separated into two stacks, one of which was sold at a
Alexus [3.1K]

Answer:

The ratio of the number of mangoes in the $3 stack to those in the $6 stack is 1 : 2

Step-by-step explanation:

Let the number of mangoes bought by the grocery store be n. Also let the number of mango sold for $3 in one stack be x and the number of mango sold for $6 in the second stack be y.

Therefore:

x + y = z                                  (1)

Also, the mangoes was sold at break even price, that is the cost of the mango and the price it was sold for was the same. Therefore:

Cost of buying = Price it was sold for

The cost of the mango = 5z and the price it was sold for = 3x + 6y

3x + 6y = 5z                            (2)

Substituting z = x + y in equation 1

3x + 6y = 5(x + y)

3x + 6y = 5x + 5y

6y - 5y = 5x - 3x

y = 2x

x / y = 1/ 2 = 1 : 2

The ratio of the number of mangoes in the $3 stack to those in the $6 stack is 1 : 2

When a number is decreased by 20% of itself, the result is 56 what is the number?
coldgirl [10]

Hey there!!

Let us take the number as ' x '

20% of x

= (20/100) × ( x )

= ( 1/5 ) × ( x )

= x/5

The number is decreased by 20% of itself

x - x/5 = 56

5x - x / 5 = 56

4x/5 = 56

Multiplying by 5 on both sides

5x = 56 × 5

5x = 280

dividing by 5 on both sides

4x / 4 = 280 / 4

x = 70

The number is 70

Hope my answer helps!

Change general form of hyperbola into standard: -x^2 + y^2 -16x + 14y - 251 = 0
topjm [15]

Answer:

(y+7)²/364 - (x+8)²/364 = 1

Step-by-step explanation:

This is the standard form of a vertical hyperbola (y-k)²/a² - (x-h)²/b² = 1

so, (y²+14y+?) - (x²+16x+?) = 251

(y²+14+49)-49 - (x²+16x+64)-64 = 251

(y+7)² - (x+8)² = 251 + 49 + 64

(y+7)² - (x+8)² = 364

(y+7)²/364 - (x+8)²/364 = 1

use the function rule, y= 2x+5, to find the values of y when x =1,2,3,4. write the answers as ordered pairs that would be used t
Lady_Fox [76]
<span>y=2(1)+5,,, y=2+5 then y=7 (1,7).....y=2(2)+5,,,y=4+5 then y=9 (2,9) .....y=2(3)+5,,, y=6+5 then y=11 (3,11)........ y=2(4)+5,,,,y=8+5 then y=13 (4,13) when solving for the y you just have to substitute the values of the x given one by one ..... for the ordered pairs -.... ex. in first equation the given value of x is 1..... so we know that is the value of x and by substituting you can find the value of y which turned to be 7 ,,, to write it (1,7) 1 is the x and 7 is the y ((x,y)
