Answer 1

Answer:

answer of q no.2

-3 and 12

Explanation:

Suppose two numbers are x and y

smaller number = x

larger number = y

Given that,

The difference of two numbers is 15

Equation 1

y - x = 15

Five times the smaller is the same as 9 less than twice the larger.

Equation 2

5x = 9 - 2y

Solve them

-x = 15 - y

x = y -15

put value of x in equation 2

5(y - 15) = 9 - 2y

-75 + 5y = 9 - 2y

-75 - 9 = -2y - 5y

-84 = -7y

y = 84/7

y = 12

x = 12 - 15

x = -3

2. 14/15
4. 56/45
6. 13/8

Answer:

2. 1

4. 1

Step-by-step explanation:

2. 8/15 + 2/5 = 14/15

since the directions say to estimate the answer is 1.

it is not 0 because it is not 1/15 etc

it is not 1/2 because it isn't 7.5/15

it is 1 because 14/15 is just one off from 15/15 which is equal to 1

4. 8/10 + 4/9 = 112/90

112/90 can be simplified by dividing by 2 so that equals 56/45

more than equal

D is correct

Step-by-step explanation:

The opposite of a negative number is the positive version of it which is 3.5 and the absolute value of a number is always the positive version of a number which would make it also 3.5.  For example absolute value of -4 is 4 and absolute value of 5 is 5.
