Answer:
x < -27
-4.5 > m/6
Step 1: Simplify both sides of the inequality.
-4.5 > 1/6 m
Step 2: Flip the equation.
1/6 m < −4.5
Step 3: Multiply both sides by 6.
6* ( 1/6 m ) < (6)* ( −4.5 )
m <− 27
Complete the following
a)

Solve the system of equations using the substitution method.
y = 2
2x+y=8
Answer: 2
Step-by-step explanation:
Kara is the manager of a video game store. She is in charge of buying the video games for the store to sell. She buys video games from a wholesaler that sells them for $10
each. The wholesaler also charges a fee of $160 for each bulk purchase. Kara then sells the video games for $14 each.
Write an equation to represent the cost to buy videos from the wholesaler. Let x represent the number of videos bought. Let y represent the total cost in dollars.
Answer: y = 10x + 160
Step-by-step explanation:
The cost follows the linear equation format of:
y = mx + c
Where:
y = dependent variable or the total cost
m is the cost per each additional unit of x
x is the number of video games
c is the constant cost or rather the fee per bulk purchase
Formula is therefore:
y = 10x + 160
Using the formula. Assuming Kara buys 100 video games, the cost would be:
y = 10 * 100 + 160
y = $1,160

Option D is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
From the figure,
3x + 46 + 14 = 90
Now,
Simplifying.
3x + 60 = 90
Subtracting 60 on both sides.
3x = 90 - 60
3x = 30
Dividing 3 into both sides.
x = 10
Thus,
The value of x on the given figure is 10.

At the end of a snowstorm, Ellie had 16 inches of snow on her lawn. The temperature then increased and the snow began to melt at a constant rate of 1 inch per hour. Assuming no more snow was falling, how much snow would Ellie have on her lawn 4 hours after the snow began to melt? How much snow would Ellie have on her lawn after tt hours of snow melting?
Answer:
12 inches
Step-by-step explanation:
1 x 4 = 4
16 - 4 = 12
Snow after 4 hours: 16 Show after t hours: -1t
Step-by-step explanation:Snow after 4 hours:
starting amount = 16
melted snow= inches per hour×4
=1×4
=
4
final amount= starting amount−melted snow
= 16−4
=12
Snow after t hours:
starting amount= 16
melted snow= inches per hour×t
=1×t
=1t
final amount= starting amount−melted snow =16-1t
