Find the are of the SHADED region.
Mazyrski [523]
First find the area of the parallelogram


Area of parallelogram = b x h
= 12 x 7
= 84

Then find area of kite

Area of kite = (xy)/2
= (7 x 12)/2
= 84/2
= 42

Now we are gonna subtract the area of the kite from the area of the parallelogram.

84 - 42 = 42

Therefore the area of the shaded region is 42.

Kenny had a total of 140 minutes to read, do homework, and play video games he spent x minutes reading, he spent 2(x+5) minutes
Licemer1 [7]

Answer:

He spent 52.5 minutes reading.

Step-by-step explanation:

The equation from the word problem is 2(x+5)+25=140. Distribute 2 to the parentheses and get 2x+10+25=140. Combine like terms to get 2x+35=140. Subtract 35 from both sides and get 2x=105. Divide both sides by 2 and your final answer is x=52.5

which equation can replace 3x 5y = 59 in the original system and still produce the same solution? 2x – y = –4 10x – 5y = –20 7x
natka813 [3]
From my research, the original system of equations contain the following equations:

<span>2x − y = −4 
3x + 5y = 59

where obtained solution is x = 3

Among the choices, it is easier to substitute </span><span>3x + 5y = 59 with one of the choices to see if they yield the same solution set. From trial-and-error, the equation that can replace the original equation is " 13x = 39 ". Among the choices, it is the 4th choice.</span>
