Answer:
Your answer is B
Step-by-step explanation:
If you count the units you can see that it is 7 units in length.
For get the solution of this task, we must make the system of equations.First it: "The quotient between the sum of two numbers and one of them is equal to 3" Let's take two values: a and b.(a+b)/b=3 --- it's will be first equation in our system.
and "The inverse of double the sum of them and equal to 1/6"1/2(a+b)=1/6 it's will be second equation in our system.
Attention at parenthesis.
System(a+b)/b=31/2(a+b)=1/6
by the first equation:(a+b)/b=3a+b=3ba=2b --- we will use this equation for second equation in system
1/2(2b+b)=1/61/3b)=1/63b=6b=2 and a=2b, that's mean a=1.The answer is pair (1;2)
Answer:
5-(3 X x)
Step-by-step explanation:
Using the values they give you:
Length= 5cm
Width= 3cm
Height= 8cm
and using the formula:
length x width x height = 5 x 3 x 8 = 120 cm^3
The volume of the box is 120cm^3

Answer: $2370</h3>
=======================================================
Work Shown:
x = price before the discount
30% of x = 0.30x = amount saved
x - 0.30x = 0.70x = price after discount = 1659
0.70x = 1659
x = 1659/(0.70)
x = 2370
