Juanita runs every third day and swims every fifth day. If Juanita runs and swims today, in how many days will she run and swim
Ber [7]

we know that

The least
common multiple (LCM) of two or more numbers is the least

number, other than zero, that is a multiple of all the numbers.

In this problem, we are looking for the least common multiple of 3 and 5

So

Multiply 3 by 5

LCM=3*5\\ LCM=15

therefore

On the 15th day after today, she will do both on the same day

the answer is

15 days

What is the answer to 4x²+7=31
Shtirlitz [24]

Answer: x2= 6

FYI: The x2 is x squared

Step-by-step explanation:

Simplifying

4x2 + 7 = 31

Reorder the terms:

7 + 4x2 = 31

Solving

7 + 4x2 = 31

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + 4x2 = 31 + -7

Combine like terms: 7 + -7 = 0

0 + 4x2 = 31 + -7

4x2 = 31 + -7

Combine like terms: 31 + -7 = 24

4x2 = 24

Divide each side by '4'.

x2 = 6

Simplifying

x2 = 6

WE has endpoints at<br>W(10, 2) and E(5, -3).<br>How long is WE?​
s2008m [1.1K]

Answer:

WE=5\sqrt{2}

Step-by-step explanation:

Distance between two points:

The distance between (x_1,y_1) and (x_2,y_2) is given by=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2

Hence distance between W(10,2) and E(5,-3)

WE=\sqrt{(5-10)^2+(-3-2)^2}=\sqrt{(-5)^2+(-5)^2}=\sqrt{25+25}\\\\WE=\sqrt{50}=5\sqrt{2}
