Answer: 264.33 + 0.05m = 291.33

Step-by-step explanation:

$26.70 a month for 800 minutes (multiply this by 9 as seen in the equation below since the bill is for 9 months)

$0.05 per additional minute (we don't know how many additional minutes were used so put an m as seen in the equation below)

email is 10% of $26.70 = $2.67 (multiply this by 9 as seen in the equation since the bill is for 9 months)

total bill is $291.33 for 9 months

put the values into an equation.

26.70(9) + 2.67(9) + 0.05m = 291.33

240.30 + 24.03 + 0.05m = 291.33

264.33 + 0.05m = 291.33

0.05m = 27

m = 540 total additional minutes

A solid cuboid is made from centimeter cubes how many centimeter cubes were used to make the cuboid
prisoha [69]

This question is incomplete because it lacks the appropriate diagram.

Please find attached this answer the appropriate diagram.

Kindly note that: The diagram was obtained from or referenced from Planes and Elevation (F) Version 3 January 2016.

Answer:

72 centimeter cubes

Step-by-step explanation:

Looking at the attached diagram, we are given 3 views of the cuboid

a) The plan view: The is the view of the cuboid from the top or a very high position

b) Front Elevation view: This is the view of the cuboid from the front

c) Side elevation view: This is the view of the cuboid from the side.

In the referenced and attached diagram,

The plan view shows us the top of the cuboid with a length of 4 and breadth of 6

The front elevation view shows us the front of the cuboid with a length of 3 and breadth of 4

The side elevation view shows us the side of the cuboid with a length is 3 and breadth of 6

We are told to find the number of centimeter cubes were used to make the cuboid. This means we are to find the volume of the cuboid.

Volume of a cuboid = Length × Width × Height

Combining the 3 views together,

The Length of the cuboid = 4

Width of the cuboid = 6

Height of the cuboid = 3

Volume of the cuboid = 4 × 6 × 3

= 72

Therefore, the number of centimeter cubes that were used to make the cuboid is 72.

The value of x is 1.25 or 1 1/4

Explanation
==============================
275x=500-125x 
Move variable to the left side and change its sign
275x+125x=500
Collect the like terms
275x+125x=500 =====> 400x=500
Divide both sides of the equation by 400
400x/400=500 =======> x=5/4 which is the same as 1 1/4 or 1.25
Hope this helps : )
