Answer:6/8
Step-by-step explanation:
Answer:
C. 14
Step-by-step explanation:
Add LM and MN
(3x + 5) + (4x + 7)
(4x + 3x) + (5 + 7)
7x + 12
As we know the total is 33
So,
7x + 12 = 33
Subtract 12 from 33, which gives me 21
Now,
7x = 21
To make x alone, divide both sides by 7, and then we will get x = 3
If x = 3
LM = 3x + 5
= (3*3) + 5
= 9 + 5
= 14
Answer:
B. 70
Step-by-step explanation:
Answer:
Option B.
Step-by-step explanation:
It is given that,
Thickness of Each DVD case = 14 mm
Thickness of each layer of padding = 10 mm
Length of the interior of the box = 132 mm
Let d represents the number of DVDs that the distributor can fit into one box with two layers of padding.
Thickness of d DVD cases = 14d mm
Thickness of two layers of padding = 10×2=20 mm
Total thickness of d DVD cases and 2 layers of padding = 14d+20
Total thickness must be less than or equal to 132.
Therefore, the correct option is B.
(1,10) satisfy the first equation and the second equation.
Since the x-coordinate is 1 and the y-coordinate is 10, you can plug these numbers in for the x and y of the equation like this:
10 = 1 + 9
10 = 10
This satisfy the first equation of y = x + 9
10 = 9(1) + 1
10 = 10
This satisfy both of the equations, so this is a solution to this system of equations.
LOL! I was in eighth grade last year, I understand the struggle! ._.
