You have to cut it up as you did there and look at it as three different rectangles, one having a length of 2 and a width of 1, another having a width of 2 and a length of 3 and lastly on having a width of 3 and a length of 4. When you find the area of each just add them all together
Answer: Each screensaver costs $2 and each Otterbox costs $7.
Step-by-step explanation:
Let x = Cost of each screensaver and y = cost of each Otterbox.
As per given, 4x+3y=29 (i)
6x +2y = 26 (ii)
Divide both sides of (i) by 2 and the multiply it by 3 on sides , we get
9x+3y=39 (iii)
Eliminate (i) from (iii) , we get
5x = 10
⇒ x = 2 [Divide both sides by 5]
Put value of x in (i), we get
4(2)+3y=29
⇒ 8+3y= 29
⇒ 3y= 21
⇒ y =7 [Divide both sides by 7]
Hence, Each screensaver costs $2 and each Otterbox costs $7.
Answer: D
Step-by-step explanation:
so we know the probability of drawing a 9 is 25 percent or 1/4 because 9 is only one and doesn't repeat.
So the cards we drawn cards we drawn 2 times so multiply 1/4 times two.
1/4 * 2/1= 2/4 = 1/2
1 2/3 = 5/3
Divide fraction, multiply reciprocal
5/3 * 8/1 = 40/3
