What are the Square numbers

Answers

Answer 1

Answer:

Answer: A square number is another way of saying a perfect square. Any integer that has an integer as its square root is a square number.

For instance, 9 is a square number because its square root is 3, and 49 also is a square number because its square root is 7.

A number such as 108 is not a square number because its square root is 10.39 which is not an integer.

-9x + 12x + 10 simplifies to

Answers

Answer:

$\boxed{\sf 3x + 10}$

Step-by-step explanation:

Simplify the following:

⇒-9 x + 12 x + 10

Grouping like terms:

⇒(12 x - 9 x) + 10

12 x - 9 x = 3 x:

⇒3 x + 10

3x+10 because you have to combine -9x and 12x which will give you 3x. Then the 10 can’t go to 3x because they aren’t like terms. So your answer is 3x+10.

You add two numbers together, and the total is 122. If you triple the smaller number and subtract 34, it will equal the larger number. What are the two numbers?

Answers

Answer: 39 and 83

Step-by-step explanation:

Let's assume the smaller number is represented by 'x' and the larger number is represented by 'y'.

According to the given information, we have two equations:

Equation 1: x + y = 122

Equation 2: 3x - 34 = y

We can solve this system of equations to find the values of 'x' and 'y'.

Substituting Equation 2 into Equation 1, we get:

x + (3x - 34) = 122

Combining like terms:

4x - 34 = 122

Adding 34 to both sides:

4x = 122 + 34

4x = 156

Dividing both sides by 4:

x = 39

Substituting the value of 'x' back into Equation 1:

39 + y = 122

Subtracting 39 from both sides:

y = 122 - 39

y = 83

Therefore, the smaller number is 39 and the larger number is 83.

On a backpacking trip through Europe, Ethan bought snacks for 10 Swiss francs. If the foreign exchange rate between the U.S. dollar and Swiss franc is 1:2, how much did Ethan spend in dollars?

If 3 1/2 pounds of bananas cost $.98, how much would one pound cost?

Answers

The way you would find how much one pound costs is divide .98 by 3 1/2. 3 1/2 in decimal form is 3.5 so .98 ÷ 3.5 = .28

So one pound of bananas would cost $0.28

Hope that helped!

98/3.5=28 centsratio and proportion3.5/98=1/xcross multiplyx= 28 cents
