The value of the solution of expression is, x = 11
We have to give that,
An expression to simplify,
4x - 7 = 2x + 15
Now, Simplify the expression by combining like terms as,
4x - 7 = 2x + 15
Subtract 2x on both sides,
4x - 2x - 7 = 15
2x - 7 = 15
Add 7 on both sides,
2x - 7 + 7 = 15 + 7
2x = 22
Divide 2 into both sides,
x= 22/2
x = 11
Therefore, the solution is, x = 11

The value of s for the given expression will be 1 / 4.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division
The given expression will be solved as:-
s + ( 1 / 4 ) = 4 / 8
( 4s + 1 ) / 4 = 4 / 8
4s + 1 = 2
4s = 1
s = 1 / 4
Therefore the value of s for the given expression will be 1 / 4.

If 120g of copper are needed for a certain piece of brass, then the weight of the zinc that will be needed for the same piece is 80 grams.
A ratio expresses the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Given that Brass is an alloy made from copper and zinc in the ratio 3:2, based on weight. Therefore, the ratio of the metals can be written as,
Copper / Zinc = 3/2
Now, as the weight of the copper is 120grams. Therefore, the ratio can be written as,
Copper / zinc = 3/2
120 grams / zinc = 3/2
zinc = (120 grams × 2) / 3
zinc = 80 grams
Hence, If 120g of copper are needed for a certain piece of brass, then the weight of the zinc that will be needed for the same piece is 80 grams.

The 1/3 portion of 6 meters can be calculated by the concept of Division and it is come out as, 2 meter
Division is a mathematical operation, in which we distribute the number in equal parts, the number on the upper side is the total quantity and the number on the bottom side is equal parts of numbers which have to be distributed.
We denote division by '÷' this symbol.
Given that,
Length = 6 meters
one third portion of 6 meter = ?
It is known that,
Division means, dividing the number in equal parts
Like- a/b is written, it means
we have to divide number a in b equal parts,
Similarly,
It can be done in calculating one third portion of the length 6 meter,
So,
One third portion = 6/3
= 2
Hence, the one third length is 2 meter

1. Distributive (the 2 is distributed)
2. Identity (multiplying by 1 doesn't change the number)
3. Associative (parentheses can move)
4. Zero (multiplying by 0 = 0)
5. Commutative (you can multiply in any order)
Question: What property is this?
Answers:
1. Distributive the 2 is distributed to everything
2. Identity multiplying by 1
3. Associative parentheses move
4. Zero multiplying anything by 0 = 0
5. Commutative order multiplied doesn't matter
