Answer:

29/61

Step-by-step explanation:

okay, first imma simplify the question a little bit.

122 students; 46 chose football; 18 chose tennis; 28girls + xboys chose running.

okay now let's find the number of students who chose running

122 - 46 - 18 = 58

now, I'll find the probability

P(Running) = 58/122 = 29/61

Select TWO equations that represent angle relationships in the figure. A 7x−9=6x+14 B 7x−9=5x−10+33 C 6x+14=33+180−(7x−9) D 33+(
Diano4ka-milaya [45]

The value of x from the figure is 1 and the equations that represent angle relationships in the figure are 7x + 5x = 3 + 9 and 12x = 12

<h3>Lines and angles</h3>

The point where two lines meet is known as an angle. From the given diagram;

7x-9 = 5x + 3

Determine the value of x

7x + 5x = 3 + 9
12x = 12
x = 12/12

x = 1

Hence the value of x from the figure is 1 and the equations that represent angle relationships in the figure are 7x + 5x = 3 + 9 and 12x = 12

Translate the sentence into an equation.
Luba_88 [7]

Answer:

The expression of the given statement is 8 y - 2  = 6.

Step-by-step explanation:

Here, let the unknown number = y

Now, product of y and 8 =  8 times  y   =   8 y

Also, two less than the product    =  Product - 2

So, two less than the product  of 8 and y =  8 y - 2

Now, this above expression is equivalent to 6.

⇒8 y - 2  = 6

Hence the expression of the given statement is 8 y - 2  = 6.

What is 4 (5×1÷20) because I dont know lol
Whitepunk [10]
Well first we need to do whatever is in the parentheses, which in this case is: (5x1/20)

Following the order of operations (PEMDAS) we start with the multiplication, which is (5x1). We know that 5x1=5, so now we can move on to the division:

5/20, which is equal to 0.25

So now that we know the answer to the equation in the parentheses is 0.25, we can solve the whole equation.

Here is the equation simplified:

4 (0.25)

Because there is now operation indicated between the 4 and the parentheses, we can assume that multiplication is implied, so the final equation is as follows:

4x0.25=1

The final answer is: 1

Hope this helps!
