Answer:

(5,15)

Step-by-step explanation:

Check x = 0,the P(x)=-225 : not an inequality solution

Check x = 10 to get -3*-5*5> 0 solutions in 5< x < 10

Check x = 20 to get -3*+5*+15<0 so no solutions in (15,+inf)

A wall is 20 feet long and requires 1,470 bricks to build. How high is the wall?
Arte-miy333 [17]

Answer: The height of wall is 10.5 feet.

Step-by-step explanation:

Since we have given that

Number of bricks to build = 1470

Length of wall = 20 feet

We need to find the height of wall.

As we know that

Bricklayer's formula is given by

N=7LH\\\\1470=7\times 20\times H\\\\1470=140\times H\\\\\dfrac{1470}{140}=H\\\\10.5\ ft=H

Hence, the height of wall is 10.5 feet.

5 less than twice a number is equal to one half the difference of three times the number and 13. Find the number.
antoniya [11.8K]

Answer:

The number will be -3.

Step-by-step explanation:

Let us assume the number as x.

Given:

⇒ 5 less than twice a number that will be 2x - 5, which is equal to half the difference of three times the number and 13

We have to find the number.

Solution:

The difference of three times the number and 13 could be represented as : 3x - 13

The value be equal to \frac{1}{2} of this 3x - 13 ⇒ \frac{1}{2}  ( 3x - 13 )

As we can see here,

  • That we got a equation ⇒ 2x - 5 = \frac{1}{2}  ( 3x - 13 )

Now, we can solve the above equation:

2x - 5 = \frac{1}{2}  ( 3x - 13 )

We have multiply both sides by 2 ⇒ 4x - 10 = 3x - 13

then, ⇒ x - 10 = -13

   ⇒   x = -3  

Hence we can say that number which was assumed as x will be -3.

GIVING BRAINLY
Virty [35]

Step-by-step explanation:

The only difference between ultimate Frisbee and basketball is the equipment; instead of using a ball, a disc is used; however, either way it is the same concept. That way, if young athletes play this game in your next practice, they may also develop an interest in ultimate Frisbee and it may be something they explore later on in their athletic careers.

The premise of this game is to pass the ball into the opposing team’s endzone and score the most points. The offensive players are not allowed to dribble the ball or allow the ball to touch the ground, if that does happen it results in a change of possession and turnover. I think this game is a fun way to teach the young athletes how to pass the ball around to their teammates and how to move to open spaces on the court. By playing this game in your practice, you are working on basketball-specific skills, but also teaching young children a sport they may have never heard of or played before; therefore, creating exposure to new activities.
