Answer:
206
Step-by-step explanation:
The formula for this problem would be -310 + 13(8) which = 206
The value of X is equal to 7
-3x + 5 > 17 |subtract 5 from both sides
-3x > 12 |change the signs
3x < -12 |divide both sides by 3
<h3>x < -4</h3>
Answer:
Alexandria requires 55 rows to use all the shells.
Step-by-step explanation:
Given:
Number of Shells = 329
Number of shells in each row = 6
We need to find the number of rows she need if she wants to use all the shells.
Solution:
Now we know that;
number of rows she needs can be calculated by Dividing Number of Shells with Number of shells in each row.
framing in equation form we get;
number of rows = 
Hence Alexandria requires 55 rows to use all the shells.
Step-by-step explanation:
3x^3+2x^2-75x-50
x^2(3x+2)-25(3x+2)
(x^2-25)(3x+2)
