Let's call the digits of the number ab a and b. Then the information in the question can be expressed as
a+b=12 => b=12-a
a*10+b + 54 = b*10+a => 9a + 54 = 9b
9a + 54 = 9(12-a) => 18a = 54 => a=3
b=12-a; b=9
39 swapped gives 93, 39+54=93
There are many sets of numbers that add up to 97. Here are just three sets of them. :) 7 + 90, 23 + 73, and 13 + 84
Your answer is C
Step-by-step explanation:
Multiply -33 x 11
Answer:
y=3x
Step-by-step explanation:
you find the slope between the two points and it tells you the y-intercept is 0 so it would be y=3x
Let's start by defining what we have and what we are looking for. We have the original area of the square, which we will call A1 We also have the area of the new square, which we will call A2 The problem tells us that A1 x 9 = A2 = 16, which means that A1 x 9 = 16 Dividing both sides by 9, we find that A1 = 16/9 Now, we also know that for any square, the area is the length of one side squared. That is, A=L2 So, A1 = 16/9 = L2 Now we take the square root of each side. √(16/9) = √L2 The square root of L2 is L, and so whatever is on the other side of the equation is equal to the length of that side. √(16/9)=√16/√9 = 4/3 Does that help?
