Answer 1

Answer:

[tex]y=1.44[/tex]

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define

[tex]\frac{4.5}{y} =\frac{12.5}{4}[/tex]

Step 2: Solve for y

Cross-multiply: [tex]4(4.5) = 12.5y[/tex]Multiply: [tex]18 = 12.5y[/tex]Isolate y: [tex]1.44 = y[/tex]Rewrite: [tex]y=1.44[/tex]

Step 3: Check

Plug in y to verify it's a solution.

Substitute: [tex]\frac{4.5}{1.44} =\frac{12.5}{4}[/tex]Divide: [tex]3.125=3.125[/tex]

Here, we see that 3.125 does indeed equal 3.125. ∴ y = 1.44 is a solution of the equation.

Answers

It’s A
It intercepts the y axis at 3 and the slope is 5 and it’s going to the left making it - so the equation is y=-5x+3

Andrea has $18 to spend. She spent $6.50, including tax, to buy a notebook. She needs to save $5.75, but she wants to buy a snack. If candy bars cost $1.15 per package including tax, what inequality would show the maximum number of packages that Andrea can buy? Solve your inequality by showing your work and steps.
plz plzpllzpzllzp help me

Answers

Answer:

The number candy bar packages must be less than or equal to 5 . The maximum number is 5.

Step-by-step explanation:

Let the number of candy bar packages be n .

6.50 - 5.75

Now we can drop the dollar signs from every number and simplify.

18 - 6.5 - 1.15n ≥ 5.75

11.5 - 1.15n ≥ 5.75

Subtract 11.5 from both sides of the inequality.

-1.15n ≥ -5.75

Divide both sides by -1.15 and flip the inequality sign.

n ≤ 5

The number candy bar packages must be less than or equal to 5 . The maximum number is 5.

(I think this is right)

The maximum number of candy bar packages must be less than or equal to 5.

What is inequality?

A relationship between two expressions or values that are not equal to each other is called 'inequality'.

Given that, Andrea has $18 to spend, she spent $6.50, including tax, to buy a notebook, she needs to save $5.75, but she wants to buy a snack, candy bars cost $1.15 per package including tax

Let the number of candy bar packages be n

18-6.5-1.15n ≥ 5.75

11.5-1.15n ≥ 5.75

-1.15n ≥ -5.75

n ≤ 5

Hence, The maximum number of candy bar packages must be less than or equal to 5.

Answer:

Step-by-step explanation:

For adding negatives, you basically just subtract. For example, -3+5. To find the answer, you subtract 3 from 5, leaving you with 2. For decimals, you add like normal, but you carry the decimal down, and leave it in the same place.

Answer:

69.77

Step-by-step

1. Put the numbers in a vertical column, aligning the decimal points

2. Add each column of digits, starting on the right and working left. If the sum of a column is more than ten, "carry" digits to the next column on the left.

3. Place the decimal point in the answer directly below the decimal points in the terms.

For example, to divide, 4/3 ÷ 2/3, you simply find the product of the first fraction and the inverse of the second fraction; 4/3 x 3/2 = 2.

Lilliana is training for a marathon. She runs the same distance every day for a week. On Monday,
Wednesday, and Friday, she runs 2 laps on a running trail and then runs 8 more miles. On Tuesday and
Sunday, she runs 4 laps on the trail and then runs 4 more miles. On Saturday, she just runs laps. How many
laps does Lilliana run on Saturday?
Step

Answers

Answer:

6 Laps

Step-by-step explanation:

Each lap is 2 Miles.

If she runs 2 laps and runs 8 more, 2x2 = 4. 8 + 4 = 12

If she runs 4 laps and 4 miles, 4x2 = 8. 8 + 4= 12

On Saturday, she has to run 12 miles so 6 x 2 = 12

She would have to run 12 laps.
