Three pounds of dried cherries cost $15.90, 5 pounds of dried cherries cost $26.50, and 9 pounds of dried cherries cost $47.70.

quester [9]

Answer:

The equation which gives the total cost y of x pounds of dried cherries is $y=5.3x$

Step-by-step explanation:

Given:

Cost of 3 pounds of dried cherries = $15.90

Cost of 5 pounds of dried cherries = $26.50

Cost of 9 pounds of dried cherries = $47.70

Let Number of of pounds of dried cherries be 'x'

Let Total Cost be denoted by 'y'

We need to find the equation for total cost y for x pounds of dried cherries.

First we will find the cost of each pound of dried cherries.

Now we know that;

3 pounds of dried cherries = $15.90

1 pound of dried cherries = Cost of 1 pounds of dried cherries

Hence By using Unitary method we get;

Cost of 1 pounds of dried cherries = $\frac{15.90}{3} = \$5.3$

Total Cost of dried cherries is equal to Number of of pounds of dried cherries multiplied by Cost of 1 pounds of dried cherries.

framing in equation form we get;

$y=5.3x$

Hence The equation which gives the total cost y of x pounds of dried cherries is $y=5.3x$

Solve each equation for y. <br> 1. 2y + 4x = 8; x = -2, 1, 3

prohojiy [21]

Answers:

IF: x = -2, THEN: y = 8

IF: x = 1, THEN: y = 2

IF: x = 3, THEN: y = -2

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. When isolating, do the opposite of PEMDAS. When solving, follow PEMDAS.

If: x = -2

Plug in -2 for x in the equation.

2y + 4 (-2) = 8

First, multiply. Note that when you multiply a negative and a positive number, your answer will be negative:

2y + (4 * -2) = 8

2y - 8 = 8

Isolate the variable, y. First, add 8 to both sides:

2y - 8 (+8) = 8 (+8)

2y = 8 + 8

2y = 16

Next, divide 2 from both sides of the equation:

(2y)/2 = (16)/2

y = 16/2

y = 8

IF x = -2, then y = 8.

If: x = 1

Plug in 1 for x in the equation.

2y + 4(1) = 8

First, multiply:

2y + (4 * 1) = 8

2y + 4 = 8

Next, isolate the variable, y. Note the equal sign; do the opposite of PEMDAS.

First, subtract 4 from both sides:

2y + 4 (-4) = 8 (-4)

2y = 8 - 4

2y = 4

Next, divide 2 from both sides to isolate y:

(2y)/2 = (4)/2

y = 4/2

y = 2

If: x = 1, then y = 2.

If: x = 3

Plug in 3 for x in the equation:

2y + 4(3) = 8

First, multiply:

2y + (4 * 3) = 8

2y + 12 = 8

Next, isolate the variable, y. Note the equal sign; do the opposite of PEMDAS.

First, subtract 12 from both sides of the equation:

2y + 12 (-12) = 8 (-12)

2y = 8 - 12

2y = -4

Next, divide 2 from both sides of the equation:

(2y)/2 = (-4)/2

y = -4/2

y = -2

If: x = 3, then y = -2.
