Answer:
3.39 ft, 2
Step-by-step explanation:
Given that a board is 10.17 feet long. Sandy needs
to cut the board into 3 equal sections.
Let x be the length of each piece then we have
ft
Each section would be 3.39 feet long.
-----------------------
When each is 5.085 feet let y be the number of pieces
Then
Two sections would be needed
Answer:
x = 35 and y = 100
Step-by-step explanation:
Let x = dollar cost per dive and y = dollar cost per night.
ATQ,
4x+3y = 440 .....(1)
and
8x + 5y = 780 .....(2)
Multiply equation (1) by 2.
8x+6y = 880......(3)
Subtract equation (3) from (2).
8x + 5y -(8x+6y)= 780-880
-y = -100
y = 100
Put the value of y in equation (1).
4x+3(100) = 440
4x = 440-300
4x = 140
x = 35
Hence, the value of x is 35 and that of y is 100.
Answer:
<h2>x = -11</h2>
Step-by-step explanation:
In algebra, the goal is always to isolate the variable, so that its value can be determined.
<h3>Step 1: Add x</h3>
6 + x = -5
<h3>Step 2: Subtract 6</h3>
x = -11
<h3>Step 3: Check</h3>
6 = -5 - -11
6 = -5 + 11
6 = 6 ✔
<h3>Step 4: Answer</h3>
x = -11

Answer:
68 m^2
Step-by-step explanation:
There are two faces that are parallelograms. Each of those has an area that is the product of length and width:
(2 m)·(4 m) = 8 m^2
There are two faces that are rectangles. Each of those has an area that is the product of length and width:
(2.5 m)·(4 m) = 10 m^2
There are two faces that are square. Each of those has an area that is the square of the edge length:
(4 m)^2 = 16 m^2
The surface area is the sum of the areas of the pairs of faces:
surface area = 2(8 m^2 + 10 m^2 + 16 m^2) = 2·34 m^2
surface area = 68 m^2
