9 right handed gloves and 3 left handed gloves were sold

<em><u>Solution:</u></em>

Let "x" be the number of right handed gloves sold

Let "y" be the number of left handed gloves sold

Cost of 1 right handed gloves = $ 45

Cost of 1 left handed gloves = $ 52

1 month 12 gloves were sold for a total of $561

So 12 gloves are sold

Therefore, frame a equation as,

number of right handed gloves sold + number of left handed gloves sold = 12

x + y = 12 -------- eqn 1

<em><u>They were sold for a total of $ 561</u></em>

number of right handed gloves sold x Cost of 1 right handed gloves + number of left handed gloves sold x Cost of 1 left handed gloves = 561

x \times 45 + y \times 52 = 561

45x + 52y = 561 --------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

From eqn 1,

x = 12 - y ------------ eqn 3

<em><u>Substitute eqn 3 in eqn 2</u></em>

45(12 - y) + 52y = 561

540 - 45y + 52y = 561

7y = 561 - 540

7y = 21

<h3>y = 3</h3>

<em><u>Substitute y = 3 in eqn 3</u></em>

x = 12 - 3

<h3>x = 9</h3>

Thus 9 right handed gloves and 3 left handed gloves were sold

konstantin123 [22]

Answer:

c. 20,000cm

Step-by-step explanation:

from is house to the park is 100m

from the park back to his house is another 100m

100m+100m=200m

1m = 100cm

200m = xcm

cross multiply

xcm = 200×100

xcm= 20,000cm

Gina is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 12 inches by 14 1/4 inc
Fittoniya [83]

Answer:

278.63 square inches

Step-by-step explanation:

Gina needs to cut two types of rectangles.

Dimensions of one rectangle is given as,

Width = 12 inches

Length = 14\frac{1}{4} = \frac{57}{4} inches

So, the area of this rectangular paper will be

Area = width × length = 12\times \frac{57}{4} = 171 inches²

Dimensions of the other rectangular paper has been given as

Width = 10\frac{1}{4} = \frac{41}{4} inches

Length = 10\frac{1}{2} = \frac{21}{2} inches

So, the area of this rectangle will be

Area = width × length = \frac{41}{4} \times \frac{21}{2} = 107.63 inches²

Thus the total area she need to cut = 171 + 107.63 = 278.63 square inches.

Find the distance from the point (1, 4) to the line y = 1/3x – 3.
Otrada [13]

Answer: Distance between line and point =

4√5 -3/2√10

Step-by-step explanation:

Distance between the line is

= √ ((9-0)²+(0+1)²)

= √ (89+1)

= √90

= 3√10

Half of the line = 3/2√10

Distance of one side of the line and the point.

= √((9-1)²+(0-4)²)

= √((8)²+(-4)²)

=√64+16

= √80

= 4√5

Distance between line and point =

4√5 -3/2√10
