2x + x = 135
3x = 135
x = 135 /3
x = 45
Nijah = 2*45 = 90 miles
Volume of a rectangular prism is = L*W*H
Volume of box A is 4800cm^3
Since price is determined by volume, and the price of box A is $6.24 we need to find the price per cm^3. $6.24/4800cm^3 = $0.0013 per cm^3
Volume of box B is 5280cm^3
5280 * 0.0013 = $6.864 which is answer c
W=0.9
So w = 0.9 and v = -4
Answer:
a = d - r + c
Step-by-step explanation:
Simply switch the terms around a bit and you have the answer.
Hope this helped!
The unknown number is - 2.5
Let the number = n
The equation will be formed as follows;
- eight times a number plus two = 8n + 2
- Two times the quantity of eight times a number plus two = 2(8n + 2)
- two times the same number minus seven = 2n - 7
- three the quantity of two times the same number minus seven = 3(2n-7)
Our final equation becomes;
2(8n + 2) = 3(2n-7)
Simplify as follow, to determine the unknown number;
16n + 4 = 6n - 21
16n - 6n = -25
10n = -25
n = -2.5
Thus, the unknown number is - 2.5
