Answer:
Step-by-step explanation:
If you consider matched parentheses to identify the contents of a "bag", the multiplier outside parentheses tells you how many bags you have. When you use the distributive property, you effectively dump all those bags on the table.
Here, the expression 4(6v +4) tells you there are 4 bags and each one contains 6v and 4. When you open them all up, you have ...
4(6v +4) = 6v +6v +6v +6v +4 +4 +4 +4
Of course, we can use multiplication to simplify repeated addition, so we can also write this as ...
4(6v +4) = 4·6v +4·4 = 24v +16
The numbers that go in your boxes are identified by their bold font style.
1.) Divide the percentage discount by 100 to convert it into decimal. For example, if a shop offers a 40 per cent discount, divide 40 by 100 to get 0,4.
2.) Multiply the decimal number by the original price to find the discount percentage. For example,if the original price is $120, 120 is multiplied by 0,4 to find the discount which is $48.
3.) <span>Subtract the discounted amount to the original price to find the actual price with the discount subtracted. For example, subtract $48 to $120 to find that the price with the discount is $72.</span>
Answer: The corrected statement is A - B = -B + A.
Step-by-step explanation: Given that the subtraction of a matrix B may be considered as the addition of the matrix (-1)B.
We are given to check whether the commutative law of addition permit us to state that A - B = B - A.
If not, We are to correct the statement.
If the subtraction A - B is considered a the addition A + (-B), then the commutative law should be stated as follows :
A + (-B) = (-B) + A.
That is, A - B = -B + A.
Thus, the corrected statement is A - B = -B + A, not B - A.
Answer:
5 liters

10 x 0.5 = 5
Answer:
x = 2
Step-by-step explanation:
Rewrite the equation as 4x - 6 = 2
Move all terms not containing x to the right side of the equation:
Add 6 to both sides of the equation.
4x = 2 + 6
Add 2 and 6.
4x = 8
Divide each term by 4 and simplify.
Divide each term in 4x = 8 by 4.
Reduce the expression by cancelling the common factors.
Divide 8 by 4.
x = 2
