Elizabeth has 8 ounces of chopped vegetables in a mixing bowl. She needs to have a minimum of 50 ounces for a party-sized salad

Lorico [155]

Answer:

the inequality is 50 = 3x -8 because Elizabeth needs 50 ounces but she already has 8 ounces, so you would have to subtract 8 from 50 first. Then to would have to see how many times 3 can fit in the difference

Visual explanation

50 = 3x - 8

take 8 from both sides

42 = 3x

divide 3 from both sides

14 = x

She needs at least 14 cups of chopped vegetables

Mo’s farm stand sold a total of 165 pounds of apples and peaches. She sold apples for $1.75 per pound and peaches for $2.50 per

9966 [12]

Answer: 65 pounds of Peaches were sold.

Step-by-step explanation:

Let the number of pounds of Peaches sold = X pounds

Therefore the pound of apple sold = (165 - X ) pounds

Total pounds of apple and peaches sold = 165 pounds

Sale made on Peaches at the cost of $2,50 per Peache = $2.50X

sale made on apple sold at the cost of $1.75 per apple = $1.75(165 - x )

Total sale made on the sale of both Peaches and apple = $337.50

Therefore , open the bracket, add everything together and equate to the total sale made which is $337.50

we now have

2.50x + 1.75( 165 - x ) = 337.50

2.50x + 1.75 x 165 - 1.75x = 337.50

2.50x + 288.75 - 1.75x = 337.50

collect like terms

2.50x - 1.75x = 337.50 - 288.75

0.75x = 48.75

divide through by the coefficient of x which is 0.75

x = 48.75/0.75

= 65pounds .

Therefore, Mo's farm sold 65 pounds of Peaches.

Check ;

65 x 2.50 = $162.5

subtract 65 from 165 to get the pound of the appel

165 - 65 = 100 pounds of apple was sold.

now multiply 100 x 1.75

= $175

Now add the two together to give the total sale ,

$162.5 + $175 = $337.50.

Which value of m will create a system of parallel lines with no solution? y=mx-6 8x-4y=12 A coordinate grid with one line labele

nydimaria [60]

Answer:

A system of parallel lines will be created where the two lines will never meet and have no common solution at a value of m = 2

Step-by-step explanation:

The equation of the given line is 8·x - 4·y = 12

Which gives;

8·x- 12= 4·y

y = 2·x - 3

Given that the line passes through the points (0, -3) and (1, -1), we have;

$Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

When (x₁, y₁) = (0. -3) and (x₂, y₂) = (1, -1), we have;

$Slope, \, m =\dfrac{(-1)-(-3)}{1-(0)} = 2$

y - (-3) = 2×(x - 0)

y = 2·x - 3 which is the equation of the given line

For the lines 8·x - 4·y = 12, which is the sane as y = 2·x - 3 and the line y = m·x - 6 to have no solution, the slope of the two lines should be equal that is m = 2

Given that the line passes through the point (1.5, 0), we have;

y - 0 = 2×(x - 1.5)

y = 2·x - 3...................(1)

For the equation, y = m·x - 6, when m = 2, we have;

y = 2·x - 6..................(2)

Solving equations (1) and (2) gives;

2·x - 3 = 2·x - 6, which gives;

2·x - 2·x= - 3 - 6

0 = 9

Therefore, a system of parallel lines will be created where the two lines will never meet and have no common solution at a value of m = 2.
