Answer:
x = 9
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 0.7 from both sides:
6.3 = 0.7x
(6.3)/0.7 = (0.7x)/0.7
x = 6.3/0.7
x = 9
x = 9 is your answer.

Write in algebraic expression
The quotient of m and 7 is equal to
In Mathematics, quotient can be defined as a terminology that is used to express or represent the division of two (2) variables or numbers.
Thus, a quotient is the division of a number or variable (quantity) by another number.
Translating the word problem into an algebraic expression, we have;

He used the commutative property incorrectly.
He used the distributive property incorrectly.
He used the associative property incorrectly.
He simplified the x coefficients incorrectly.
He simplified the x coefficients incorrectly.
Step-by-step explanation:
In performing the operation, he should group the like terms together.
In this case, the terms with an x and those without.
This will be written as;
6.7x-3.4x-2x-3-1-2

Step-by-step explanation:
Answer:
24 pints of blue paint used to create 40 pints of purple paint .
Step-by-step explanation:
As given
Hugo is mixing blue paint with red paint to create purple paint.
The ratio of blue to red is 3 to 2.
Let us assume that the x be scalar mutiple .
Thus
Pints of blue paint used = 3x
Pints of red paint used = 2x
As given 40 pints purple paints is made by mixing blue paint with red paint .
Than the equation becomes
2x + 3x = 40
5x = 40
x = 8
Thus
Pints of blue paint used = 3 × 8
= 24 pints
Therefore 24 pints of blue paint used to create 40 pints of purple paint .
