The equivalent expression is,

⇒ - 24

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 10 (- 2 2/5)

Now,

Since, The expression is,

⇒ 10 (- 2 2/5)

Solve as;

⇒ 10 × ( - 12/5)

⇒ - 10 × 12/5

⇒ - 2 × 12

⇒ - 24

Thus, The expression is equivalent to - 24.

Answer:

2000+21=2021

its a very cool thing u got inur mind!!

Correct principal is $1200.

Answer:

R = 6.736%

Step-by-step explanation:

Formula for simple interest is;

Interest = PRT/100

We are given;

Principal; P = $1200

Time; T = 6 years

Interest; I = $485

Rate; R =?

From, Interest = PRT/100, we have;

485 = 1200 × R × 6/100

Making R the subject gives;

R = 485 × 100/(6 × 1200)

R = 6.736%

~I hope I helped you :)~

Answer: a = 10

Step-by-step explanation:

3/5 = a + 5/25

Multiply both sides by 25 to get rid of it:

3/5 * 25 = 25(a + 5) /25

15 = a + 5

a = 15 - 5

a = 10

Answer: 5 x 58 = 290           :)

Step-by-step explanation:

x=50  

Step-by-step explanation:

angle 1 and 3 are corresponding angles that menas they equal the same

so set it up like this 2x+10=110 solve for x

move over the 10, subtract 10 from 110 you get 100 and divide by 2

you get 50.

=================================================

Explanation:

Angles 1 and 3 are vertical angles which are congruent.

angle 1 = angle 3

110 = 2x+10

2x+10 = 110

2x = 110-10

2x = 100

x = 100/2

x = 50

Answer:

16x²

Step-by-step explanation:

since all sides of a square are equal, we just multiply 4x by 4x. this gives us 16x².

The area of square with side length 4x is 16x.

A square is a two-dimensional closed shape with 4 equal sides and 4 vertices.

Given,

The side length of a square is 4x

We need to find the area of square.

As we know that area of square = 4a.

Where a is the length of side of a square.

In a square all the four sides will have same length.

a=4x

Area of square=4(4x)

=16x

Hence the area of square with side length 4x is 16x.

Answer: 270 students altogether

There are 150 girls.

Answer:

$450

Step-by-step explanation:

First, find an equation that represents the proportional relationship between number of months (x) and amount spent (y).

A proportional equation can be represented in the form, y = kx, where,

k = constant of proportionality = y/x

Using a point on the line, (1, 50),

k = 50/1 = 50.

Substitute k = 50 into y = kx

The equation would be:

y = 50x

After 9 months (x), they would pay the following:

Substitute x = 9 into y = 50x

Thus:

y = 50(9)

y = 450

Answer:

x = 30

Step-by-step explanation:

A triangle's angles add up to 180

Also, angles on a straight line add up to 180

180-100 = 80

80+70=150

180-150=30

Answer:

x = 30

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

100° is an exterior angle of the triangle, then

x + 70 = 100 ( subtract 70 from both sides )

x = 30

Answer:

Coordinates of Steve's House are S (3,2)

The required coordinate of the Steves's house is (3,2).

The map below shows the locations of the houses of Maria Reese and Paul, coordinates of Steve's house who lives 2 miles from Paul and 1 mile from Reese is to be determined.

Coordinate, is represented as the values on the x-axis and y-axis of the graph

Here,
Since Steve's house lives 2 miles from Paul's, So the Y coordinate of Steve's house will raise to 2 more than the Y coordinate of Paul, So Y = 0 + 2 = 2
Now, Steve's house lives 1 mile from Reese x coordinate of Steve's house will raise to 1 more than the x coordinate of Reese, So X = 2 + 1 = 3

Thus, the required coordinate of the Steves's house is (3,2).
