Answer:

Step-by-step explanation:

-5 x 15 = -75

This is according to the rule -a ÷ a = -a and -a x a = -a. Where a negative divided/multiplied by a positive number equals a negative number.

There is an unknown number •it is a four digit number •the tens are double the ones •the thousands are double the tens •the sum

oksano4ka [1.4K]

Answer:

8542

Statement

1.It is a four digit number

2.The tens are double the ones

3.The thousands are double the tens

4.The sum of the digits is nineteen

Step-by-step explanation:

It is a four digit number

lets take 4 digit number-ABCD

The tens are double the ones

$C=2D$ -----------------------------1

The thousands are double the tens

$A=2C$ -------------------------------2

According to equation 1 and 2

$A=4D$

If we take

$D=1,2$

Possible number

$4B21$ OR $8B42$

The sum of the digits is nineteen

I use hit and trial method

$4B21$ - If I take B is maximum

$4+9+2+1\neq 19$

$8B42$ - If, i try to find value of B

$8+B+4+2=19$ ---------------------3

$14+B=19\\B=19-14\\B=5$

So the unknown number is- 8542

Evaluate the problem below. Please show all your work for full credit. Highlight or -4 1/2+5 2/3

lubasha [3.4K]

Answer:

$\frac{7}{6}$

Step-by-step explanation:

$-4\frac{1}{2} + 5\frac{2}{3} =$

For the first term you have to multiply 2x(-4) and add 1, for the second term you have to multiply 3x5 and add 2.

$\frac{2(-4)+1}{2} + \frac{3(5)+2}{3} =$

$-\frac{9}{2} +\frac{17}{3} =$

Now you need to find the lowest common multiple between the denominators, just cross multiply as it is shown:

$-\frac{9}{2} (\frac{3}{3} )+\frac{17}{3} (\frac{2}{2} )=$

$-\frac{27}{6} +\frac{34}{6} = \frac{7}{6}$

finally you get the result by doing a substraction = 7/6, or 1 $\frac{1}{6}$
