A real world expression would be Toby had makes 3 dollars per hour he wants to buy a ps4 for 40 dollars. he already has 10 dollars. how many hours does he have to work to afford his ps4. 3x+10=40
Answer:
2a * 5b
Step-by-step explanation:
2 times a = 2a
5 times b = 5b
The phrase "the product" shows the 2 elements are being multiplied together.
The formula is L*W*D, right?
So for the cube, since all sides are equal then the Length, Width and Depth would all be 8 unless otherwise specified. 8*8*8=512
The rectangle would be 10*2*3&1/2 or 10*2*3.5=70
I hope this is correct but if you want check my work with a calculator to make sure.
Answer: 172
Explanation:
<u>Mystery</u> <u>Science Fiction</u> <u>Biographies</u>
4x 3x
4y 5y
Science Fiction = 48
3x = 48 ⇒ x = 16
4y = 48 ⇒ y = 12
Mystery: 4x = 4(16) = 64
Biographies: 5y = 5(12) = 60
Mystery + Science Fiction + Biographies = Total
64 + 48 + 60 = Total
172 = Total
