d = v \times t

d = 2 \times 80

\frac{80}{2}

answer = 40

What would be an equation that gives you the 3 consecutive numbers of 72
Vera_Pavlovna [14]
I'm not sure what you mean by "the 3 consecutive numbers of 72".

Do you mean 3 consecutive numbers that ADD UP TO 72 ?

If that's what you want, then you can use this equation:

The middle number . . . . . x
The smallest number . . . . (x-1)
The biggest number . . . . . (x+1)

The equation:        (x-1)   +   (x)   +   (x+1)   =   72 .

Boil that equation down, and you discover that  x=24 .

So the 3 numbers are  23,  24,  and  25 .

Explain how to decide which is a better value. 4 greeting cards for $10 and 6 greeting cards for $14.
xxMikexx [17]

Answer:

I dont know if this is supposed to be solved a certain way for a class, but as a bargain shopper, this is what I would do to figure out the best value.

Step-by-step explanation:

First divide $10 by 4:   10.00/4=2.5 or $2.50 per card

Then, divide $14 by 6:  14.00/6=2.3333333 so about $2.33 per card

Now, just look at the two answers and see which one is less.

If you buy 4 cards for $10, you will pay $2.50 for each card and if you buy 6 cards for $14, you will pay about $2.33 for each card. Therefore, the better value would be the 6 cards for $14.

Someone please help me I’m so confused!!!
QveST [7]

Answer:

number one.  186in^{2}  number two.  36cm^{2}

Step-by-step explanation:

FOR NUMBER ONE:

the area of a trapezoid formula is   \frac{a+b}{2} h where a and b are the bases and h is the height. so we have to add in the numbers into the formula

\frac{12+15}{2} * 6\\ = <em>81</em>

and the paralellogram formula is b×h.  where b is the base and h is height

15 × 7 = <em>105</em>

so the area of the figure is 81 + 105 is 186 in^2

FOR NUMBER TWO:

the area of the square formula is s^{2}.   where s is the side

4^2 = <em>16</em>

and for the paralellogram is b × h

4 × 5 = <em>20</em>

so the area of the figure is 16 +20 = 36 in^2

hope this helps! ;)
