Answer 1
Answer:

D

Step-by-step explanation:

let's rewrite this

x + y = 11                  - equation 1

   - x = - y - 9           - equation 2

solve the first equation for x

x + y = 11            (add -y to both sides to get x by itself)

     x = -y + 11           - equation 3

now substitute -y + 11 for x in the second equation

 y - 11 = - y - 9        (2 negative signs next to each other equals positive)

2y - 11 = -9              (add y to both sides)

      2y = 2               (add 11 to both sides)

        y = 1                (divide both sides by 2)

now substitute y = 1 into equation 3

x = -1 + 11

x = 10

therefore, x = 10 and y = 1. in coordinates, x goes before y

therefore, the coordinates are (10, 1)

therefore the answer is D

good luck my friend! hope this helped a lot! also, i found a website if you don't fully understand this, its called MathPapa, i didn't use it to work this out so my working might be different but it definitely helps me sometimes. for an equation like this, type it likes this: x+y=11; -x=-y-9

Lucy purchase a swimsuit and a towel. The towel represent 30% of the total cost. If she spent $15.00 on the towel, then what was her purchase total

Answers

Answer:

$50

Step-by-step explanation:

Given data

Let the total purchase be x

Hence 30% of x is $15

Let us find the value of x

30/100*x= 15

0.3*x=15

0.3x=15

x= 15/0.3

x= $50

Hence the purchase is $50

Answer:

$50 is the total

Step-by-step explanation:

30% over 100% =  15 over x

then you cross multiply and get:

30x = 1500

you then divide both sides by 30

30 and 30 cross out

1500 ÷ 30 = $50

put them from least to greatest ​

Answers

Answer: -7/10, -0.35, 1/5, 0.95

Step-by-step explanation:

-7/10 =  -.7

1/5 = 0.2

Answer:

From least to greatest, the correct order is [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.

Step-by-step explanation:

Since all negative numbers are smaller than positive, you immediately know that [tex]-\frac{7}{10}[/tex] and -0.35 are smaller than [tex]\frac{1}{5}[/tex] and 0.95. The greater the absolute value of a negative number is, the smaller that number is. Because [tex]-\frac{7}{10}[/tex] is -0.7, which has a greater absolute value than -0.35, this means [tex]-\frac{7}{10}[/tex] is the smallest number, and -0.35 is the second smallest number. Since [tex]\frac{1}{5}[/tex] is 0.2 which is smaller than 0.95, the correct order from least to greatest would be [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.

A trapezoid is shown. The length of one base is 10 and the length of the other base is 6. The height of the altitude is 5. A small rectangle with height 2 and length 3 is cut out of the bottom of the trapezoid. What is the area of the composite figure? units2

The area of the composite figure is 34 square units.

The formula for the area of a trapezoid is:

Area = (1/2) × (sum of bases) × height

Here, the sum of the bases is 10 + 6 = 16, and the height is 5.

Thus, the area of the trapezoid before the rectangle is cut out is:

Area of trapezoid = (1/2) × 16 × 5 = 40 units²

The height of the rectangle is 2, and the length is 3.

Therefore, the area of the rectangle is:

Area of rectangle = length × height

= 3 × 2

= 6 units²

To find the area of the composite figure, we subtract the area of the rectangle from the area of the trapezoid:

Area of composite figure = Area of trapezoid - Area of rectangle

= 40 units² - 6 units²

= 34 units²

Therefore, the area of the composite figure is 34 square units.

A number cube is rolled twice. What is the P (2 and then odd number)?

Answers

Answer:

P (2 and then odd number) = [tex]\frac{1}{12}[/tex]

Step-by-step explanation:

Probability refers to chances of occurrence of any event.

A number cube is rolled twice.

Possible outcomes are as follows:

[tex](1,1),(1,2),(1,3),(1,4),(1,5),(1,6)[/tex]

[tex](2,1),(2,2),(2,3),(2,4),(2,5),(2,6)[/tex]

[tex](3,1),(3,2),(3,3),(3,4),(3,5),(3,6)[/tex]

[tex](4,1),(4,2),(4,3),(4,4),(4,5),(4,6)[/tex]

[tex](5,1),(5,2),(5,3),(5,4),(5,5),(5,6)[/tex]

[tex](6,1),(6,2),(6,3),(6,4),(6,5),(6,6)[/tex]

Total number of outcomes = 36

Favorable outcomes include outcomes with 2 and then odd number.

So,

Favorable outcomes are [tex](2,1),(2,3),(2,5)[/tex]

Number of favorable outcomes = 3

Probability is equal to number of favorable outcomes divided by total number of outcomes.

Therefore,

P (2 and then odd number) = Number of favorable outcomes ÷ Total number of outcomes

[tex]=\frac{3}{36}[/tex]

[tex]=\frac{1}{12}[/tex]
