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.

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

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

HELP Plssss..... The m

Answers

Answer:

Step-by-step explanation:

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°.

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

What is x?

Answers

Answer:

Yoy answer is x=10

Step-by-step explanation:

We already know what ∠GEF is 23°

so you would have to create an equation like this [tex]23+(5x+1)=7x+4[/tex]

you add 23+1=24 and get [tex]5x+24=7x+4[/tex] subtract 5x on both sides

[tex]24=2x+4[/tex] subtract 4 on both sides

[tex]20=2x[/tex] divide 2 x=10

∠DEF=7(10)=70+4=74

∠DEG=5(10)=50+1=51

To check 51+23=74

Help me pls i need soon
Tksss

Answers

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

So we have the equation:

[tex]5^x+5^{x+1}=150[/tex]

First, separate the second term:

[tex]5^x+(5\cdot5^x)=150[/tex]

Let u equal 5ˣ. So:

[tex]u+5u=150[/tex]

Combine like terms:

[tex]6u=150[/tex]

Divide both sides by 6:

[tex]u=25[/tex]

Substitute back u:

[tex]5^x=25[/tex]

Take the base 5 logarithm of both sides:

[tex]\log_5(5^x)=\log_5(25)[/tex]

The left cancels:

[tex]x=\log_5(25)[/tex]

Evaluate the right:

[tex]x=2[/tex]

So, our answer is 2.

And we're done!
