Ms. Garland bought x number of shirts for the new members of her chorus. The cost for X number of shirts, including $3.99 shipping was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. Which equation could be used to find X?
A. 3.99(x + 12.25) = 77.49

B. 3.99x + 12.25 = 77.49

C. 12.25 (x + 3.99) = 77.49

D. 12.25x + 3.99 = 77.49

Answers

Answer 1

77.49 - 3.99 = 12.25 * x

73.5 = 12.25x
(Divide both sides by 12.25)
6 = x
So, she bought six shirts.

Answer:

x=31

Step-by-step explanation:

Since these angles are on a straight line, they are supplementary (combine to make 180 degrees. Therefore we can set up an equation to find x.

(5x-16)+(x+10)=180

Drop the parentheses.

5x-16+x+10=180

Combine like terms.

6x-6=180

Add 6 to both sides.

6x=186

Divide both sides by 6.

x=31

HTH :)

Answer is 31

How you solve this is:
The whole line equals to 180 degrees so add 5x-16+x+10=180 that’s will be your equation. And then subtract 10 to 180 so then it will be 5x-16+x=170 then add 16 to 170 and you will be left with 5x+x=186 add the x’s together and get 6x divide 6 to 186 and then x=31

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.

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

Answers

Answer:

x = 33

Step-by-step explanation:

This picture shows a supplementary angle which means:

angle 1 + angle 2 = 180°

In order to solve for x, you need to add both the angles

(2x + 1) + (4x - 19) = 180° start by simplifying this equation by adding like terms

6x - 18 = 180° you can solve this like a regular inequality now, add 18 to 180°

6x = 198 now divide 6 by 162

x = 33

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]

The number line that represents [tex]m = 4[/tex] is number line (c)

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).

Maria Said that:

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