Add 8v to both sides. you get, 1-7v-8v+8v=-8v-8v+8v. The 8v cancels out and you then get, 1-7v=-8v. Add 7v to both sides. 1-7v+7v=-8v+7v. then you get, 1=-1v. divide by -1 and you get v=-1

1-7v-8v=-8v-8v
1 = -8v -8v +8v +7v
1 =-1v
v = 1/-1
v=-1

The range of three numbers is 17.the mode is 24 and the median is 24 ? What are the three numbers?

vivado [14]

The answer is 7, 24, 24.

The median is the middle number.

The mode is the number which occurs the most.

The range is the difference between the largest number and the smallest number.

Since 24 is the middle number, it is the median.

Since 24 is also the number which occurs the most often, it is also the mode.

To find range, do 24-7 which is equal to seventeen.

Tell how the Communicative property of addition and the Associative property of addition can help solve the problem mentally 8+(

topjm [15]

Step-by-step explanation:

Communicative property states that, in addition, integers added in any order will still give the same answer.

So in this question,

rather than first adding 8 + (-5), we add 8 + (-8)

We know that a number + its additive Inverse (opposite sign) is equal to zero

And we know any number added to zero is equal to the number.

So we can quickly find out that the sum is -5
