If you mean for the last one:
Triangle area=1/2bh
=1/2(4)(3x-5y)

Area of rectangle=l•w
=8(6x-y)

So combing them you get:
[(1/2)(4)(3x-5)]+[8(6x-y)]
Simplify: [8(3x+5)]+48x-8y
=24x+40+48x-8y
=72x-8y+40

You'd have to be given x and y to find a true value

Cannon sells the IVY REC for $130. Early crowdfunders could buy it for $104. What is this discount written as a percent?
MrMuchimi

Answer:

20%

Step-by-step explanation:

First, find the difference between $130 and $104. This equals $26, and to find this discount written as a percent, divide $26 by the original cost of the camera. 26/130=0.2, which represents a 20% discount.

The sum of 5 consecutive even numbers is 100. What is the first number in this sequence?
gayaneshka [121]

Answer:

16

Step-by-step explanation:

Let's represent this with an equation, where x is the first number. The next number must be x+2, because it has to be even, not x+1, and the rest continue the same way:

x+(x+2)+(x+4)+(x+6)+(x+8) = 100

Solve for x.

5x+20 = 100

5x = 80

<u>x = 16</u>
