Answer:

Step-by-step explanation:

a) 64 (A=bh)

b) 96 ((16x12)÷2)

Answer:

Step-by-step explanation:

a) base = AB = 16 cm

height = DX = 6cm

Area of  the parallelogram = base * corresponding height to the base

                                            = 16 * 6

                                            = 96 sq. cm

Area of parallelogram =  96 sq .cm

BC * DY = 96

12 * DY = 96

      DY = 96/12

      DY = 8 cm

Tavon has a gift card for $65 that loses $2.50 for each 30-day period it is not used. He has another gift card for $55 that loses $2 for each 30 day period it is not

a Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal
b. What will the value of each card be when they have equal value?

Answers

Let x be the number of 30 days.

(a) 65 - 2.5x = 55 - 2x

(b) 65 - 2.5x = 55 - 2x
65 - 55 = 2.5x - 2x
0.5x = 10

Step-by-step explanation:

Let x=0.687687....

Then 1000x=687.687687...

Subtract x from 1000x

999x = 687

11/15 minus 1/3 in simplified form

Answers

Answer:

[tex] \frac{2}{5} [/tex]

Step-by-step explanation:

[tex] \frac{11}{15} - \frac{1}{3} \\ \frac{11}{15} - \frac{1 \times 5}{3 \times 5} \\ \frac{11}{15} - \frac{5}{15} \\ \frac{6}{15} \\ \frac{6 \div 3}{15 \div 3} \\ \frac{2}{5} [/tex]

11/15 - 1/3 is 2/5.

Given that we need to simplify 11/15 - 1/3.

So,

There must be a common denominator in order to subtract fractions. Since both 3 and 15 can be divided into it in this instance, the common denominator is 15.

If you multiply the numerator and denominator of 1/3 by 5/5 to get a denominator of 15, you can write 11/15 - 1/3 as (11/15) - (5/15).

You can now take the numerators away:

(11/15) - (5/15) = (11 - 5)/15 = 6/15

By dividing the numerator and denominator by their largest common factor, which is 3, the fraction 6/15 can be made even simpler:

6/15 ÷ 3/3 = 2/5

Therefore, 11/15 - 1/3 is 2/5.
