Answer:
y > 7
Step-by-step explanation:
2y > 20-6
2y > 14
2y/2 > 14/2
y > 7
Answer:
B) 1
Step-by-step explanation:
Since we are using elimination, we can just cancel 2y and -2y. No need of multiplying anything if we are just looking for x.
We add the equations and get:
9x=9
Then divide and the final answer is:
x=1

You divide 32 by 4 and it should be a whole number because 32 is a factor of 4 ....the answer is 8
Answer:
- small prism: 630 m²
- large prism: 2520 m²
Step-by-step explanation:
The total surface area of the prism is the sum of the base area and the lateral area. The base area is made up of two right triangles, so will be the product of the triangle leg dimensions. The lateral area is made up of three rectangles whose width is that of the prism and whose equivalent length is the perimeter of the triangle base.
For the smaller prism, the area is ...
(20 m)(21 m) +(3 m)(20 m + 21 m + 29 m) = 420 m² +210 m² = 630 m²
The larger prism is similar, with a scale factor of 2, so its area will be 2² = 4 times that of the smaller prism:
4×630 m² = 2520 m²
__
In summary, the total surface area of each prism is ...
- small prism: 630 m²
- large prism: 2520 m²
Let d equal the final amount it depreciates.
Let m equal the number of months.
Since d is the final amount, we put this at the very end of the equation.
Since it depreciates $25 every month, this number is going to be subtracted from the total price of the tablet ($650).
The final equation comes out too: d = 650 - 25m
Best of Luck!
