Answer with steps!... Thanks

Mathematics
1 answer:
NNADVOKAT [17]3 years ago
5 0

Answer:

A)  False

B)  True

Step-by-step explanation:

For A) First let's do x/11 = 15. If you solved it by now, you will know that the answer is 0.7333333. So now you just do 11x15. Because the answer is different then the answer we got when doing the division, the answer for A is false

For B) B is definitely true because equation are any mathematical sentences that have an equation symbol. So it's like saying 8x3=24 and 6x4=24. These two equations end up with the same answer so B is true.

I hope this helped you find out the rest :)

1 4/5+ 2 2/3=what<br><br> 5 7/8 - 3 1/2=what<br> 1 1/2+ 3 1/5=what<br> 7 5/6- 5 1/2=what
lilavasa [31]

Answer:

1.) 4 7/15

2.) 2 3/8

3.) 4 7/10

4.) 2 1/3

Step-by-step explanation:

1.) 1 4/5 + 2 2/3

3 + 4/5 + 2/3

LCD = 15

3 + 12/15 + 10/15

3 + (12 + 10)/15

3 + 22/15

3 + 1 7/15

4 7/15

2.) 5 7/8 - 3 1/2

(5 x 8 + 7)/8 - 3 1/2

47/8 - 3 1/2

47/8 - (3 x 2 + 1)/2

47/8 - 7/2

LCD = 8

47/8 - 28/8

19/8

2 3/8

3.) 1 1/2 + 3 1/5

4 + 1/2 + 1/5

LCD = 10

4 + 5/10 + 2/10

4 + (5 + 2)/10

4 7/10

4.) 7 5/6 - 5 1/2

(7 x 6 + 5)/6 - 5 1/2

47/6 - 5 1/2

47/6 - (5 x 2 + 1)/2

47/6 - 11/2

LCD = 6

47/6 - 33/6

(47 - 33)/6

14/6

7/3

2 1/3

Which statement is true out of the value of money that you save increases over time , the value of money remains constant over t
Nataly_w [17]
None is necessarily true.

Even though you have your money in an interest-bearing savings vehicle, its value (purchasing power) may actually decrease if the interest rate is not at least as great as the inflation rate.

In periods of inflation, the value of money decreases over time. In periods of deflation, the value of money increases over time. It tends to be difficult to regulate an economy so the value of money remains constant over time.

The present value of money is greater than the future value in inflationary times. The opposite is true in deflationary times.

_____
In the US in the middle of the last century, inflation rates were consistently 2-3% per year and savings interest rates were perhaps 4-6%. Money saved actually increased in value, and the present value of money was greater than the future value. These days, inflation is perhaps a little lower, but savings interest rates are a lot lower, so savings does not outpace inflation the way it did. The truth or falsity of all these statements depends on where and when you're talking about.
