Answer: x represents the number of months, 150 represents one-time materials fee, 2( 21x + 75 ) represents total fees in x months and 42 represents rate of change.
Step-by-step explanation:
Since, Here the expression 2( 21x + 75 ) represents the monthly tuition and the one-time materials fee that Jamie pays for his two children to join a science club.
Let, f(x) represents the monthly tuition fee
Therefore, f(x)= 2( 21x + 75 )
⇒f(x)= 42 x +150
Again according to the question, there is a one-time materials fee which must be free from the variable.
Therefore In f(x) , 150 must represent one time material fees.
And, x is variable, and here number of months is a variable.
Thus, x must be denote the number of months.
And, 42 must be denote the fees for 1 month.
Answer:
q=24
Step-by-step explanation:
the opposite of division is multiplication so 4x6=24. then you check this by of course imputing your answer into the equation. 24 ÷ 6 =4
the answer is c=10s-0.10s
Answer:
The box is 5 inches tall
Step-by-step explanation:
The given dimensions of the video games are;
The length of the video game, L = 15 inches
The width of the video game, W = 10 inches
The volume of the video game box, V = 750 cubic inches
Assuming that the shape of the video game box is a cuboid, we have;
The formula for the volume of a cuboid, V = Length, L × Width, W × Height, H
∴ V = L × W × H
The height of the cuboid, H = V/(L × W)...(1)
Where, for the video game box;
L = Length = 15 in.
W = Width = 10 in.
V = Volume = 750 in.³
Plugging in the values of the variables in equation (1) gives;
H = V/(L × W) = 750 in.³/(15 in. × 10 in.) = 5 in.
The height of the box, H = 5 inches.
