Explain how you could mentally find 8 x 45 by using the distributive property
Answers
Hope this helped
8x45
8(40)+8(5)
320+40
360
360 is the solution of the given mathematical expression.
To mentally find the product of 8 and 45 using the distributive property, you can break down one of the factors into smaller, more manageable parts.
First, decompose 45 into two parts, such as 40 and 5.
Now, you can distribute the factor of 8 to both parts:
8 x 40 + 8 x 5
Next, simplify each part individually:
8 x 40 = 320
8 x 5 = 40
Finally, add the results together:
320 + 40 = 360
So, mentally applying the distributive property, you can find that 8 multiplied by 45 equals 360.

Answer: $11.81✔️cost of the sandwich before tax
Step-by-step explanation:
Let C = cost before tax
Cell phone costs = C + C·5% = $12.40
C(1 + 0.05) = $12.40
C = $12.40/1.05 = $11.81 , cost before tax
Answer: $11.81✔️ cost of the sandwich before tax
Checking
Cell phone after tax = $11.81 + $11.81·5/100
Cell phone after tax = $11.81 + $0.59 = $12.40✔️checked!

−4y−4+(−3) PLZ SOMEONE HELP
Answers
Final answer:
The expression −4y−4+(−3) simplifies to −4y −7 by combining the numeric constants according to the rules of addition for negative numbers.
Explanation:
To combine the like terms in the expression −4y−4+(−3), we look for terms that have the same variable raised to the same power. Here, there are no like terms withy, so we just combine the constant numbers.
Following the rules for addition and subtraction of numbers:
1. When two negative numbers add, the answer has a −ve sign. For example, −4 + (−3) = −7.
2. In subtraction, change the sign of the subtracted number and then follow the addition rules.
Applying these rules to the given expression:
−4y−4+(−3)= −4y + (−4) + (−3)
= −4y + −7
Therefore, the equivalent expression after combining like terms is −4y −7.
