Peggy completed 5/6 of the math homework and Al completed 4/5 of the math homework. Did Peggy or Al complete more of the math homework?

Answers

Answer 1
Answer:

Answer:

Peggy completed more of the math homework than Al

Step-by-step explanation:

we have

Peggy completed 5/6 of the math homework

Al completed 4/5 of the math homework

we know that

In order to be able to compare fractions more easily it is recommended that both have the same denominator

so

Multiply 5/6 by 5/5

5/6(5/5)=25/30

Multiply 4/5 by 6/6

4/5(6/6)=24/30

25/30> 24/30

therefore

Peggy completed more of the math homework than Al
Answer 2
Answer: Peggy 5/6 x 5 = 25/30
Al        4/5 x 6 = 24/30

Peggy completed more of the math homework

Tickets to a museum cost $17 each. For a field trip, the museum offers a $4 discount on each ticket. How much will tickets for 32 students cost?

Answers

17-4=$13
So our tickets now cost $13
So multiply that by 32
13•32=$416
For this problem you sinply multiply 4 by 32.

4 x 32 = 128

Therefore it will cost $128 for a field trip with 32 students

state whether ordered pair of numbers is a solution of the sentence:3y>2x+1;(4,3)

Answers

3y > 2x + 1

You have asked us to check out the point where  x=4  and  y=3 .
All we need to do is to plug those numbers in place of 'x' and 'y',
and see whether the resulting statement is true:

3y > 2x + 1

3(3) > 2(4) + 1

On the left side, 3(3) is the same as 9.
On the right side, 2(4) + 1 is the same as (8 + 1) and that's 9 .

So the statement says:    9  >  9 ,  and that's not true.
9 is equal to 9, it is not greater than 9 .

So this point is not a solution of the inequality.

3\cdot3>2\cdot4+1\n 9>9

It's not.

Solve the inequality. 6x + 3 > 3x + 30

Answers

6x+3>3x+30

The thing about solving inequalities, you just need to treat the symbol, which is the less than symbol in this case, as an equal sign.

So our problem becomes: 6x+3=3x+30

Now we solve this like a normal algebra problem.

First, get all the variables on one side. Since 3x is smaller than 6x, we'll get rid of that by subtracting it from each side.

3x+3=30 is what we end up with.

Now to get the variable alone and get rid of that constant. To do that, we are going to subtract 3 from each side.

We end up with 3x=27

Now, to get the 'x' alone, we need to divide each side by 3.

x=9 is what we end up.

BUT WE FORGOT TO DO SOMETHING

We started this as an inequality problem, so we need to end it as an inequality solution.

Since there wasn't any negatives we need to worry about (Which is something else entirely) we just need to transfer the symbol we started with down.

x>9

What are the like terms in this expression? 9a - 3b + 4ab A) 9a and -3b B) 9a and 4ab C) 9a, -3b, and 4ab D) no like terms

Answers

there are no like terms in that equation...
There are no like terms because each term has different set of variables, where a does not equal b does not equal ab.
