What is five×fivewhat is the answer for 4 x 5
Mandarinka [93]
Well 
<span>
4 x 5 = 20 

and

5 x 5 = 25

I'm sure a calculator could help you out with this, But if you don't have access to a calculator I'll show you how to multiply. It's just like adding, Let's use 6 x 7 for example. Take the first number ( Which is 6 in this case ) and look at the second number ( Which would be 7 ) The second number represents how many times you would add the first number together. So:

6 + 6 + 6 + 6 + 6 + 6 + 6 = 42 ( We add 6 together 7 times )

So

6 x 7 = 42

There are faster methods but this is probably the best way to start out.

A music store is offering a Frequent Buyers Club membership. The membership costs $22 per year, and then a member can buy CDs at
sammy [17]

Answer:the cost of each CD for a member is $5.25

Step-by-step explanation:

The membership costs $22 per year, and then a member can buy CDs at a reduced price.

Let x represent the cost of each CD for a member.

Let n represent the number of CDs that each member buys. This means that the total cost of buying n CDs for a member for a year would be

22 + nx

If a member buys 17 CDs in one year, the cost is $111.25. This means that

17x + 22 = 111.25

17x = 111.25 - 22 = 89.25

x = 89.25/175 = 5.25

Ef is the median of trapezoid abcd (please explain the answer im so confused lol)
Art [367]

Step-by-step explanation:

Okay, so...

The Median of a trapezoid is directly in the middle. For some weird mathimatical reason you won't ever need to know unless it's on an exam or you become a math major, its midsegment is the average of the top length and the bottom length.

In other words,

EF = ( BC + AD ) / 2

So for part 1, we can use that equation to find x.

EF = ( BC + AD ) / 2

  • Insert known equations.

4x-18=[(x+12)+(3x-4)]/2

  • Simplify within parentheses.

4x-18=[x+12+3x-4]/2

4x-18=[x+3x+12-4]/2

  • Add.

4x-18=[4x+8]/2

  • Divide.

4x-18=2x+4

  • Simplify.

(4x-2x) +(-18+18)=(2x-2x)+(4+18)

2x=22

  • Divide both sides by 2.

x=11

Part 2 is a lot easier now. All we have to do is plug in 11 for x.

BC =x+12

BC = 11+12

BC = 23

-

AD = 4x-18

AD = 4(11)-18

AD = 44-18

AD = 26

-

EF = 3x-4

EF = 3(11)-4

EF = 33-4

EF = 29

Answer:

Part I: x = 11

Part II:

  • BC = 23
  • AD = 26
  • EF = 29
