What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here the given expression is :
3(a-2b)
where, a = -3
and, b = -12
Now, substitute the value of a and b in the given expression :
3(a-2b)
= 3(-3-2x -12)
= 3(-3 + 24)
= 3(21)
= 63
Therefore, the solution of the given expression is 63.

What is the largest rational number which satisfies the inequality 2x≤ 7.
Step by step answer
Answer:
[tex]x\leq \frac{7}{2}[/tex]
Step-by-step explanation:
To get this answer, you would need to divide 2 from both sides.
--
Since 2 can't go into 7 respectfully, it would remain 7 over 2 unless converted into a decimal which is 3.5 [Which would make the answer x ≤ 3.5]
--
Hence, the answer would be 7/2 as it's final answer

Use a net to find the surface area of the square pyramid.
Answer: 208
Step-by-step explanation:
Base:8x8=64
8x9x4divided by 2=8x9x2=144
Answer:
208 feet^2
Step-by-step explanation:
This figure has four triangular sides and a square bottom. Given that the length of one side of the square base is 8 feet and the slant height 9 feet, we apply the area-of-a-triangle formula A = (1/2)(base)(height) to find the area of one side: A = (1/2)(8 feet)(9 feet) = 36 feet^2.
Since there are four sides, we multiply this result by 4, obtaining the total surface area of the sides: 144 feet^2.
Finally, we calculate and add the area of the base, which is (8 feet)^2, or 64 feet^2.
The total surface area of this square pyramid is thus 144 feet^2 + 64 feet^2, or 208 feet^2.

Determine the range of the following graph:
Answer:
[-8, 7] also, - 8 ≤ y ≤ 7Step-by-step explanation:
As we know,
Range : Is how far the graph goes from down to up.
So here,
Furthest down point of y = - 8
Furthest upper point of y = 7
Hence,
Range will be [-8, 7] also, - 8 ≤ y ≤ 7

Jessie graphed one of the lines in a system of equations: y = 3 x minus 2. If the system has an infinite number of solutions, which statements are true? Check all that apply.
On a coordinate plane, a line goes through (0, negative 2) and (1, 1).
Any point in the coordinate plane is a solution because it has an infinite number of solutions.
Point (1, 1) is a solution because it is one of the points on the line already graphed.
It is impossible to tell if (–1,–5) is a solution without seeing the other line graphed.
Point (20, 58) is a solution because it results in a true statement when the point values are substituted into the equation of the line.
When the other line in the system is graphed, it will share all points with the line already graphed.

Jess deposited 38 times for savings in March, 23 times in April and 25 times in May. How many times did Jess make savings deposits over this time period?
Answer:
Step-by-step explanation:
1.) 25 + 23 + 26 -33 = 41 coins
2.) 120 - 60 - 24 = 36 cupcakes left to make
3.) 31 +15 +20 = 66 tickets needed
(34 - 9) + x = 66
25 + x = 66
x = 41 tickets needed
4.) 210 - 27 - 77 - 65 = 41
5.) 6 + (6 + 6) + (6 + 6 + 6) = 36 blocks
6.) 38 + 27 + 35*2 = 135 items (or 100 if you count both shoes together)
7.) 348 - (120 + 132) = 96 gold plates
8.) (11 + 9 +12) - 4 = 28 blocks
9.) this question is unclear, she either ordered 3 items (as in types, off the menu) or 38+ 32 + 37 = 107 total items
10.) 38 + 23 + 25 = 86 times that she deposited savings

Three dice, each with faces numbered 1 through 6, are arranged as shown. Seven faces are visible. Find the sum of the numbers on all the faces that are not visible.
Answer:
37
Step-by-step explanation:
First, we need to find the sum of all the numbers of the dice. The expression 3(1 + 2 + 3 + 4 + 5 + 6), or 3(21) does that for us. 3 × 21 = 63. So the sum of all of the numbers of the dice is 63. But we already know 7 of the numbers there: 2, 3, 1, 6, 5, 4, 5. In the expression 3(21), we counted these numbers as well. So now we can add these 7 numbers together then subtract them from 3(21), or 63. We can write the expression 3(21) - (2 + 3 + 1 + 6 + 5 + 4 + 5), or 3(21) - 26 = 63 - 26 = 37.
The required sum of the numbers on all the faces that are not visible is 37.
Given that,
Three dice, each with faces numbered 1 through 6, are arranged as shown. Seven faces are visible.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
According to the question,
Sum of not visible number = 3[1 + 2 + 3 + 4 + 5 + 6] - [sum of visble number]
= 63 - 25 = 37
Thus, the required sum of the numbers on all the faces that are not visible is 37.
