The answer should be 8 dogs are terriers
Answer:
a. (8 × 2) = (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2) = 16
b. (8 × 2) = (2 × 8) = (8 + 8 ) = 16 {Using the commutative property}
c. It is easier to calculate (8 + 8 ) than (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2).
Step-by-step explanation:
Multiplication operation is equivalent to the repeated addition operation.
For example (3 × 4) can be treated as 3 groups of 4 or 4 + 4 + 4 then use the addition facts to learn the multiplication facts.
a. Now, (8 × 2) can be treated as 8 groups of 2 or 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 then using the addition facts we get (8 × 2) = (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2) = 16
b. If we apply the commutative property of multiplication then (8 × 2) = (2 × 8) and we can assume it as 2 groups of 8 or (8 + 8) i.e. 16 which makes it easier to get the multiplication process by addition operation.
c. It is clear that (8 + 8) is much more easier to calculate than (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2) by addition operation. (Answer)
159 + 163 + 156 = 478
You would then need to round it up to the nearest ten which would make it 480 miles.
Answer: The multiplication property of equality is used to transform the equation from the first step to the second step.
Explanation:
The multiplication property states that if any number is multiplied both side of a equation the equation doesn't change.
If x = y and we multiply both side by m, then xm = ym is equivalent to x = y.
The given expression is,

Use multiplication property of equality, multiply 5 both sides,


Therefore, the multiplication property of equality is used to transform the equation from the first step to the second step.
A²+b²=c²
The hypotenuse of the triangle is c. (the slanted line, if it is a right triangle)
Simply fill in the variables, square them, and solve for the missing number.
Check out the picture, it is just an example.
Don't forget: the variable you are finding needs to be squared, that means that when you find your answer, find the square root of it.
