Betty had $70. She bought a necklace for $9 and a ring for $7. Which expression correctly shows the total money Betty has left? A $70 − (−$9) + (−$7) B $70 + (−$9) + (−$7) C $70 − (−$9) − (−$7) D $70 + (−$9) − (−$7) A B C D

Answers

Answer 1
B is the correct answer.
This is because the numbers in the parentheses have a negative sign in front of them. If you have an equation that "subtracts" a negative number, the sign would change to the opposite and you would have to add. To avoid that, you have to put an addition sign to subtract correctly.
✅70+(-9)+(-7)=70-9-7
❌70-(-9)-(-7)=70+9+7

Round your answer to the nearest cent, as necessary.

Answers

The answer is 748.19$

The drama club has 14 members. They need to raise $952.00 to attend a play at the Fox Theater. They already have $126 in their account. What is the least amount of money each student needs to raise in order to go to the play?

A- m ≥ 59
B- m ≥ 60
C- m ≥ 64
D- m ≥ 68

Answers

Answer:

A- m is greater that or equal to 59

Step-by-step explanation:

So, they need to raise at least $(952-126)=826.

826/14=59. So each member has to raise at least $59.

952-126=826
826/14=59

Maria said that -4n + 3 +9n - 4 is equivalent to 4n. What error did maria likely make?

Answers

Maria combined all of the factors, which were not all like terms. She should’ve did -4n+9n and 3-4 to get 5n-1

The error that Maria did was combining all the factors in the algebraic expression without collecting the like terms to a particular side to solve for the variable (n).

What is an Algebraic expression?

Algebraic expression involves solving numbers with variables with the use of arithmetic operations e.g.

AdditionSubtractionMultiplicationDivision

Claim:

Maria Said that:

-4n + 3 + 9n - 4 = 4n

If we ignore the like terms and assume all numbers have a variable (n);

Then, we have:

to rent a car for a trip, four friends are combining their money. The group chat shows the amount of money that each puts in. One expression for their total amount in 189 plus 224 plus q.

a.) Use the Commutative Property to write two equivalent expressions.
b.) If they need $500 to rent a car, find at least two different pairs of numbers that p and q could be.

Answers

Answer:

1. 189+224+87  2.  500- 189-224

B. q=87

Step-by-step explanation:

The Commutative Property to write two equivalent expressions are (189+p)+(224+q) or (224+q)+(189+p) and  p=44 and q=43 is a pair of numbers or  p=45 and q=42 is another pair of numbers which satisfy the condition of car.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

The amount of money that each friend puts in One expression for their total amount in 189 plus 224 plus q.

189+p+224+q

the Commutative Property to write two equivalent expressions.

(189+p)+(224+q)

or (224+q)+(189+p)

Now if they need $500 to rent a car,

then 189+p+224+q=500

413+p+q=500

Then p=44 and q=43 is a pair of numbers or  p=45 and q=42 is another pair of numbers.

Hence, the Commutative Property to write two equivalent expressions are (189+p)+(224+q) or (224+q)+(189+p) and  p=44 and q=43 is a pair of numbers or  p=45 and q=42 is another pair of numbers which satisfy the condition of car.

Which of the following number lines represents the solution to m/-2 - 7 = -9?

Answers

Answer:

Step-by-step explanation:

the answer is a. (the first one)

Number lines are used to represent relationship between numbers at regular intervals

The number line that represents the equation [tex]\frac{m}{-2} - 7 = -9[/tex] is number line (c)

The equation is given as:

[tex]\frac{m}{-2} - 7 = -9[/tex]

Add 7 to both sides of the equation

[tex]\frac{m}{-2} = -2[/tex]

Multiply both sides of the equations by -2

[tex]m = 4[/tex]

This means that, the solution to the equation is [tex]m = 4[/tex]
