Answer 1

Answer:

The value of the expression will be 23.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the expression is (7+5b)+1. Then the value of the expression at b = 3 will be:-

E = 7+5b)+1

E = 7 + ( 5 x 3 ) + 1

E = 7 + 15 + 1

E = 23

Therefore, the value of the expression will be 23.

in local theaters showing an animated movie they charge $5 per ticket for a child and $12 per ticket for an adult they sell a total of 342 tickets and make a total of $2,550 we want to try to find out how many of each type of ticket they so let C represent the number of children tickets sold and A represent the number of adult tickets to write an equation that represents the fact that 342 tickets were sold also write an equation representing the fact that they made it to a total of 2550 also solve the system you created in A & B by the method of elimination

Answers

Answer: C=222 and A =120

Step-by-step explanation:

Let C be the number of children tickets and A be the number of adult tickets.

Then, According to the question, we have the following system:-

$C+A=342........................(1)\n5C+12A=2550........................(2)$

Multiply equation (1) by 5 on both sides ,we get

$5C+5A=1710..........(3)$

Eliminate equation (3) from equation (2), we get

$7A=840\n\Rightarrow\ A=120$

Substitute the value of A in (1), we get

$C+120=342\n\Rightarrow\ C=222$

Hence, the number of children tickets sold = 222 and the number of adult tickets sold =120

C+A=342
$5C+$12A=$2,550

5C+5A=1710
5C+12A=2550
-7C=-840
C=120

5(120)+12A=2550
600+12A=2550
12A=1950
A=163

Describe the dimensions of two different prisms that each have a volume of 2400 cubic centimeters. Then draw each prism.

Answers

One prism with a volume of 2400 might have a rectangular base with a length of 4 and a width of 5, as well as a height of 120.

V = l x w x h
V = 4 x 5 x 120
V = 2400

This prism would essentially look like a really tall rectangle, since the height is such a large number. I wouldn't accurately represent the units on graph paper, if I were you. Just label the sides with the numbers I gave you.

Another prism with a volume of 2400 might be a rectangular prism with a length of 8, a width of 10, and a height of 30.

V = l x w x h
V= 8 x 10 x 30
V = 2400

This would also be a tall rectangle, although it isn't as tall. Keep in mind that l x w x h is only the volume formula for a rectangular prism. I only used rectangular prisms because they would be the easiest for this example. A triangular prism has a different volume formula.
