Answer:
Step-by-step explanation:
Given: 10 less than 
is 35.
To find: The equation of the given situation.
Solution: We need to write an equation for 10 less than is 35.
Here, we will break down the sentence to form the equation.
10 less than means 
.
Then, it says 10 less than is 35 which means it is equal to 35.
So, the sentence 10 less than is 35 can be written as 10 less than is equal to 35.
Now, 10 less than is equal to 35 can be shown as .
Therefore, the required equation is .
Answer:

Step-by-step explanation:
Multiply 12 * 320 to receive 3,840
Answer:
cant be factored
Step-by-step explanation:
Answer:
A two-digit number can be written as:
a*10 + b*1
Where a and b are single-digit numbers, and a ≠ 0.
We know that:
"The sum of a two-digit number and the number obtained by interchanging the digits is 132."
then:
a*10 + b*1 + (b*10 + a*1) = 132
And we also know that the digits differ by 2.
then:
a = b + 2
or
a = b - 2
So let's solve this:
We start with the equation:
a*10 + b*1 + (b*10 + a*1) = 132
(a*10 + a) + (b*10 + b) = 132
a*11 + b*11 = 132
(a + b)*11 = 132
(a + b) = 132/11 = 12
Then:
a + b = 12
And remember that:
a = b + 2
or
a = b - 2
Then if we select the first one, we get:
a + b = 12
(b + 2) + b = 12
2*b + 2 = 12
2*b = 12 -2 = 10
b = 10/2 = 5
b = 5
then a = b + 2= 5 + 2 = 7
The number is 75.
And if we selected:
a = b - 2, we would get the number 57.
Both are valid solutions because we are changing the order of the digits, so is the same:
75 + 57
than
57 + 75.
