A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin. You instead decide to make
mini-muffins, and the recipe yields 20 mini-muffins. If you eat 7 mini-muffins, how many calories will you consume?

Answers

Answer:

If you eat 7 mini-muffins, will you consume 1134 calories.

Step-by-step explanation:

A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin.

i.e.

No of muffins = 12 muffinsCalories per muffin = 270 calories

Total calories of standard muffins = 270 × 12 = 3240 calories

If the same amount of calories are made by 20 mini-muffins, then the total number of calories per mini-muffin will be:

3240/20 = [tex]162[/tex] calories per muffin

As you ate 7 mini-muffins.

Thus,

Your eaten calories = 162 × 7             ∵ 162 calories per muffin

                                 = 1134 calories

Therefore, if you eat 7 mini-muffins, will you consume 1134 calories.

What values of x will satisfy the inequality 4x + 2 > 10?

Answers

Answer:

x > 2

Step-by-step explanation:

4x + 2 > 10

Subtract 2  from both sides;

4x > 8

Divide both sides by 4;

x > 2

Answer:

x > 2

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Property

Step-by-step explanation:

Step 1: Define

4x + 2 > 10

Step 2: Solve for x

Subtract 2 on both sides:                    4x > 8Divide 4 on both sides:                        x > 2

Here we see that any value x greater than 2 would work as a solution to the inequality.

A taxi cab in Myrtle Beach charges $2 per mile and $1 for every person. If a taxi cab ride for two people costs $12, how far did the taxi cab travel?

Answers

Answer:

i believe 5 miles

Step-by-step explanation:

$12 - $2 (for the two people in the taxi cab since it costs $1 every person)

= $10

then to find out the number of miles they traveled since it costs $2 you can divide 10 by 2 and get 5 which means they traveled 5 mes

Answer:

with two people and $12, the cab will travel 5 miles

Step-by-step explanation:

equation:

2x + y = 12

x - total distance

y - # of people

12 - total cost

2x + 2 = 12

x = 5 miles

slope =-5, y-intercept =-2

Answers

Answer:

y = -5x - 2

Step-by-step explanation:

y = mx + b

m = -5

b = -2

Step-by-step explanation:

I am not completely sure what your question is, but if you want to write an equation, you can just plug in the values for m and b to get y=-5x-2. If you wish to graph it, start at (0,-2) because that is your y-intercept. Next, move up 5 units and to the left 1 unit since the slope is negative. Now you have the point (-1,3). Connect the dots to get the graph.

Answers

Hello,

The correct answer is x = -5/3
Alternate forms: x = 1 2/3, x = 1.6

Step-by-step:

Remove parentheses

6 + 3x + 12 = 13

Add the numbers

18 + 3x = 13

Move constant to the right

3x = 13 - 18

Calculate the difference

3x = -5

Divide both sides

x= -5/3
