Answer:

<h2>22</h2>

Step-by-step explanation:

We have the isosceles triangle.

AC\cong AB

Therefore we have the equation:

2x-24=x-2                 <em>add 24 to both sides</em>

2x-24+24=x-2+24

2x=x+22              <em>subtract x from both sides</em>

2x-x=x-x+22

\boxed{x=22}

BC=x

thereofre

BC=22

Answer:

22

Step-by-step explanation:

it shows in the image that AC and AB are isosceles so 2x - 24 would be equal to x - 2

2x - 24 = x -2 ➡ x = 22

Lerok [7]

Answer:

If today is Saturday, then after 70 days, we will be on a Saturday again.

3) Find two consecutive even integers such that their sum is equal to the difference of 3 times the larger &amp; 2 times the sma
swat32

Answer:

In assumption, x is the smaller even integer and x+2 is the next so it will be larger.

The integers are 4 and 6

Step-by-step explanation:

Let the two consecutive even integers be x and x+2

Here x is the smaller even integer and x+2 is the next so it will be larger.

Now according to the given statement

Sum of both: x+x+2

difference of 3 times the larger & 2 times the smaller:3(x+2)-2x

Putting the sum and difference equal:

x+x+2 = 3(x+2)-2x

Solving the equation

2x+2 = 3x+6-2x\\2x+2 = x+6\\2x+2-x = x+6-x\\x+2 = 6\\x+2-2 = 6-2\\x = 4

The next integer will be:

x+2 = 4+2 = 6

Hence,

In assumption, x is the smaller even integer and x+2 is the next so it will be larger.

The integers are 4 and 6.

Robert plays cricket. He hit the ball in such a way that it goes up 180 feet
PilotLPTM [1.2K]

Answer:

4 feet per second

Step-by-step explanation:

Hi there!

v=D/t where v is velocity (speed), D is distance and t is time

Plug in the known values (D=180 feet, t=45 seconds)

v=180/45\\v=4

Therefore, the speed of the ball is 4 feet per second.

I hope this helps!
