Answer:

A) The value of a is <u>29</u>.

B) The value of b is <u>greater than 29</u>.

C) In both part A and part B we have used a common property  which is addition property and that we have add 9 on both side of equation in both parts.

D) The value of a in part A is equal to 29 whereas in part B the value of b is greater than 29.

Step-by-step explanation:

Solving for Part A.

Given,

a-9=20

We have to solve for a.

a-9=20

By using addition property of equality, we will add both side by 9;

a-9+9=20+9\\a=29

Hence the value of a is <u>29</u>.

Solving for Part B.

Given,

b-9>20

We have to solve for b.

b-9>20

By using addition property of inequality, we will add both side by 9;

b-9+9>20+9\\b>29

Hence the value of b is <u>greater than 29</u>.

Solving for Part C.

In both part A and part B we have used a common property  which is addition property and that we have add 9 on both side of equation in both parts.

Solving for Part D.

The value of a in part A is equal to 29 whereas in part B the value of b is greater than 29.

Given: -6x &lt; 36. Choose the solution set. {x | x &lt; -6} {x | x &gt; 6} {x | x &gt; -6} {x | x &lt; 6}.
grin007 [14]

The correct answer is this inequality {x | x > -6}

What does a math inequality look like?

The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3.

Given that:

-6x < 36

we multiply -1 on both the sides

6x > -36

divide 6 on both the side

x > -6

Hence the correct answer is this inequality {x | x > -6}.

In a group of 60 numbers, average of
Arada [10]

Answer:

c. 18

Step-by-step explanation:

First, you would find the total sum of the 60 numbers. The average is always the sum of the numbers divided by the number of numbers.

35*18=630

15*10=150

Now we do not know how many numbers the last group has. However, we can find it out doing 60-35-15 to see how many numbers are left. There would be 10 numbers left

10*30=300

630+150+300=1080

1080/60=18

Hence, the answer is C(18)
