13.

Step-by-step explanation:

Cross multiply:  [tex]\frac{3x-15}{2}=\frac{2x+10}{3}[/tex]

Remove the brackets: 3(3x-15) = 2(2x+10)

Move the terms: 9x-45 = 4x+20

Collect like terms and calculate: 9x-4x=20+45

Divide both sides: 5x = 65

A group of workers took 123.6 hours to
complete a job. A smaller group of workers
will complete the same job, but it will take
them 1.15 times as long as it took the first
group. How long did it take the smaller group
to complete the job?

Answers

Answer:

137.814 hours

Step-by-step explanation:

We simply need to multiply the time by the multiplier given in order to find the time it took for the smaller group

123.6 hours is the time and 1.15 is the multiplier

123.6x1.115=137.814 hours

Which operation has to be calculated first in this expression?
7 – (4 + 5)

Answers

Answer:

Addition

Step-by-step explanation:

You should add 4 and 5 first because of PEMDAS.

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

Since 4+5 is in parentheses it should be done first.

Answer:

Addition

Step-by-step explanation:

This the answer because:

1) First, we have to know the Order of Operations

2) An easy way of remembering this is PEMDAS or GEMS

PEMDAS : Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

GEMS : Grouping (Parenthesis), Exponents, Multiplication and Division (whichever one comes first from left to right), Addition and Subtraction (whichever one comes first from left to right)

3) In this expression, parenthesis would be first because that's what comes first in the order of operations

4) Inside the parenthesis is another expression where you need to add. Therefore, the answer is addition

George has $15. He would like to know if he has enough money to see a movie ($9.00) and buy a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each). George incorrectly used this numerical expression to decide if he had enough money.


15 - 9 + 2.65 + 1.35 + 2(1.74)

Use the order of operations to simplify this expression.

Answers

Answer:

Yes, he has enough money and your simplified answer is below. If I'm wrong correct me or give me a comment.

Step-by-step explanation:

15 - 9 + 2.65 + 1.35 + 2(1.74) Multiply first.

15 - 9 + 2.65 + 1.35 + 3.48  Then just add or subtract from the left to the right

6 + 2.65 + 1.35 + 3.48

8.65 + 1.35 + 3.48

10 + 3.48

13.48 would be the simplified answer.

Hey there!!!

According to the question,

Angle P is three less than twice less of an angle Q.

Then, let angle Q be x then angle P is 2x-3.

Now, it has also given that they are supplementary angle.

We know that the sum of supplementary angle is 180°.

Therefore, x+ 2x - 3°=180°.

Or, 3x = 180°-3°

Or, x = 177°/3

Therefore the measure of angle Q is 59° and P is 2×59°-3°= 121°.

Which graph shows a polynomial function of an odd degree?

Answers

Answer:

THE ANSWER IS C ON EDGE.

Step-by-step explanation:

If both sides of the graph are pointing in the same way, THE FUNCTION HAS AN EVEN DEGREE.

The degree of a polynomial is the highest power of the polynomial.

Graph 3 has an odd degree.

From the attachments, we have the following highlights

The first graph crosses the x-axis, 4 timesThe second graph crosses the x-axis, 6 timesThe third graph cross the x-axis, 3 timesThe fourth graph cross the x-axis, 2 times

The above highlights mean that:

Graphs 1, 2 and 4 have even degrees, because they have an even number of  x-interceptsGraphs 3 have an odd degree, because it has an odd number of  x-intercepts

Hence, graph 3 has an odd degree.

Marisol earns overtime pay when she works more than 9 hours in a day. So far, she has worked 4 hours today. Write, and solve an inequality to show the values of x that will allow Marisol to earn overtime this shift.

PLSS HELP ASAPPP URGENT GOOD AND REAL ANSWERS ONLY

Answers

so basically you wanna think about what you know...she’s worked 4 hours, but she needs to get over 9 hours in order to get overtime.

we’re using x as the variable representing hours worked (other than the 4 hours already)

knowing this, we can set it up so that we have

4 + x > 9

and the. solve
4 + x -4 > 9 -4

x > 5

so this basically means that she needs to work over 5 more hours in order to earn overtime this shift

Four-fifths of a number equals 16. Find the number.


The number is 20

The number is 31

The number is 17

Answers

Answer:

The number is 20

Step-by-step explanation:

Four-fifths = 4/5

Let the number = x

4/5 of x = 16

4/5 * x = 16

4/5x = 16

Divide both sides by 4/5

x = 16 ÷ 4/5

= 16 × 5/4

= 80 /4

= 20

Therefore, the number is 20
