Problem situation: Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. How many cups, x, will Bernie need to sell to make a profit of at least $20? Inequality that represents this situation: 20≤1.50x−6.50 Drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.

12-3*y = 0

Subtract 12 from both sides:

-3 * y = -12

Divide both sides by -3:

y = 4

Answer:

y=4

Step-by-step explanation:

Standard form:

−3y + 12 = 0

Factorization:

−3(y − 4) = 0

Solutions:

y = 12/3   = 4

Isolate the variable by dividing each side by factors that don't contain the variable:

y=4

Answer: division

x = 6

Step-by-step explanation:

Simplifying

7x = 42

Solving

7x = 42

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '7'.

x = 6

Simplifying

x = 6

Answer:

95 degrees

Step-by-step explanation:

Since the sum of the angles in a quadrilateral must add up to 360 degrees:

95+85+Z+85=360

Z+265=360

Z=95 degrees

Hope this helps!

Answer:

Z = 95°

Step-by-step explanation:

if W = Y => X = Z => Z = 95°

Answer:

Pretty easy (if you know geometry)!

Step-by-step explanation:

First, we know that A and B have angle bisectors. This means the angles that are divided by that angle bisector are equal (or their measures).

Thus, m<DBA= 1/2 Beta; m<DAB=1/2 Alpha.

Time to find m<ADB. Using the sum of all angles in a triangle = 180* theorem, we can come up with this equation:

[tex]180= m<ADB+\frac{1}{2} \alpha +\frac{1}{2} \beta[/tex]

So, solving:

[tex]180-\frac{1}{2} \alpha -\frac{1}{2} \beta =m<ADB[/tex]

So there you go! Hope this helps!

Answer:

Area of polygon MNOPQR = 13 units

Step-by-step explanation:

Area of smaller rectangle:

(7-3)= 4 units  multiplied by (3-2) = 1 unit

= 4 sq. units.

Area of polygon MNOPQR

= 3*3 units + 4*1 units

= 9 units + 4 units

= 13 units

The exponential function represented by the values is f(x) = 4(0.5)ˣ.

An exponential function is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

From the table, at point (0, 4):

4 = ab⁰

a = 4

At point (2, 1):

1 = ab²

1 = 4b²

b² = 0.25

b = 0.5

The exponential function represented by the values is f(x) = 4(0.5)ˣ.

Answer:

Applies are £0.50 each and bananas £0.80 each.

Step-by-step explanation:

Represent the numbers of apples and bananas by a and b respectively.

Then:

5a + 4b = £5.70, and:

4a + 2b = £3.60

Let's solve this system using elimination by addition/subtraction.  Multiply the 2nd equation by -2, obtaining the equivalent system

5a + 4b = £5.70

-8a  - 4b = -£7.20

--------------------------

-3a         =  -£1.50

Dividing both sides by -3, we get £0.50.  Apples are £0.50 apiece.

How much are bananas per piece?  Use the first equation; substitute £0.50 for a:

5(£0.50) + 4b = £5.70, or

                  4b = £3.20.  Then b = £0.80.

Applies are £0.50 each and bananas £0.80 each.

Answer:

-5x + 0y = -11

The y terms are eliminated

Step-by-step explanation:

- 4x – 2y = -2

X - 2y = 9

We want to subtract the second equation from the first

Distribute a minus sign to all the terms in the second equation

- 4x – 2y = -2  

X - 2y = 9

= (-5x + 0y = -11)

Answer:

60cm

Step-by-step explanation:

1:50 means every foot is 50 feet.

So I would think the ship hes making will be 2 feet long.

Every foot is equal to 0.3m which is equal to 30cm

Every foot is equal to 30cm

2 x 30cm = 60cm

Answer:

a. 60 boys

b. 228 total students

Step-by-step explanation:

a. If there are 45 girls and the ratio of girls to boys is 3:4, then there are 60 boys. The common multiple is 15.

3 * 15 = 45

4 * 15 = 60

45:60 = 3:4

——————————

b. First we need to find out how many boys there are.

95 / 5 = 19

19 * 7 = 133

So, there are 133 boys and the given number of girls is 95. To find out how many total students there are, we need to add 133 and 95.

133 + 95 = 228

Answer:

45% of students are female or 15/32

Step-by-step explanation:

We find out their is 72 Boys and 60 Girls

We add both together to get 132 Students

Then we divide to get our number/fraction

60/132 = 15/32 or 45%

Answer:

13/4 * 5/2

Step-by-step explanation:

In the question, it says that her coach wants her to run 2 1/2 TIMES the original 3/4 she had ran. Therefore, you would want to make the fractions into improper fractions, and then multiply, which is how you would get 13/4 * 5/2.

Answer:

201, 500ft²

Step-by-step explanation:

The formula for calculating area in this case is;

A = w × l

This means we're going to take the width of the runway (65ft) and multiply it by the length of the runway (3100ft).

(To make it easier on paper, you can swap the two numbers around, so the higher number is on top, and the smaller number is on the bottom - 3100 × 65. It won't change the answer, but it will make it quicker and easier to get to the result, and lessens the chances making a mistake.)

So the equation you need to do is;

3,100 × 65 = 201, 500.

Add on the units, and there's your answer;

201, 600ft²
