Find the area of a parallelogram with base 15 yards and height 21 2/3

icang [17]

Answer:

A = 325 yd^2

Step-by-step explanation:

The area of a parallelogram is found by multiplying the base times the height

A = bh

A = 15* 21 2/3

Changing the mixed number to an improper fraction

21 2/3 = (3*21+2)/3 = 65/3

A = 15 * 65/3 = 15/3 *65 = 5*65 =325

A = 325 yd^2

5x + 7y = 17 x + 4y = 19

REY [17]

<h2>Answer:</h2>

5x + 7y = 17 ....(1)

x + 4y = 19 .....(2)

From equation 2

x + 4y = 19

x = 19 - 4y

Putting the value of x in Equation (1)

5(19 - 4y) + 7y = 17

95 - 20y + 7y = 17

- 20y + 7y = 17 - 95

-13y = -78

y = $\frac{78}{13}$

y = 6

Now, putting the value of y in equation (2)

x + 4y = 19

x + 4(6) = 19

x + 24 = 19

x = 19 - 24

x = -5

Therefore, the value of y is 6 and value of x is -5
