3n + 7 - 11n - 31 = 160
Answer:
n = -23
Step-by-step explanation:
3n + 7 - 11n - 31 = 160
Step 1: Combine like terms
-8n - 24 = 160
Step 2: Simplify
-8n = 184
n = -23
Answer:
= −23
Step-by-step explanation:
Subtract the numbers
3 + 7 - 11-31 = 160
3-24 - 11 = 160
Combine like terms
3 - 24-11 = 160
-8 - 24 = 160
Add 24 to both sides of the equation
-8 - 24 = 160
-8 - 24 + 24 = 160 + 24
Simplify
Add the numbers
Add the numbers
--> -8 = 184
Divide both sides of the equation by the same term
-8 = 184
-8/-8 = 184/-8
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
--> = -23
The volume and base area of a rectangular cargo container is 720 cubic
meters and 120 square meters. Find the height of the container? *
A)86,400m3
B)400m3
C)4m
D)6m
Answer:
D, 6m
Step-by-step explanation:
Step one:
Given data
The volume and base area of a rectangular cargo container is 720 cubic
= 720m^3
The area of the cargo container is 120 m^2
Required
We want to find the height of the container
Step two
The expression for the volume is given as
Volume= Area* height
so,
720= 120*h
divide both sides by 120
720/120= h
h= 6 m
The height is 6m
What is the solution to the linear equation 2/3 x - 1/2 = 1/3 + 5/6x

Step-by-step explanation:
use difference of squares
if my answer is correct, pls mark this is brainliest! thanks!
Since both terms are perfect squares, factor using the difference of squares formula,
a² − b² = (a + b) (a − b) where a = 4n² and b=1.

Jane can fill
cases and will have
bottles left.
Answer:
a) 265 case
b) 4 bottles
Step-by-step explanation:
The number of bottles remaining = total number of bottles - total number of bottles placed in cases
The number of bottles remaining = 8500 - 2136
The number of bottles remaining = 6364 bottles
From the table, we can see that water is filled at 24 bottles per case. Let x be the number of cases, hence:
24 bottles per case * x case = 6364 bottles
24x = 6364
x = 6364
x = 265.16
Therefore the number of cases filled = 265.
265 cases can contain 6360 bottles
b) number of bottles remaining = 6364 bottles - (24 * 265 case) = 4 bottles
