please explain how you got your answer too!

Answer:

A: $2,600

Step-by-step explanation:

0.15m = 390

Isolate the variable m by diving both sides by 0.15

0.15m ÷ 0.15 = 390 ÷ 0.15

m = 2600

Answer:

She spent $10.12

Step-by-step explanation:

8.60*.07 = .602, round that to .60

8.60 + .60 = 9.2

9.2*.10 = .92

9.2 + .92 = 10.12

Answer:

$10.12

Step-by-step explanation:

Do $8.60 + $8.60(7%) = $9.20

Then $9.20 + $9.20(10%) = $10.12

Answer:

1 7/10

Step-by-step explanation:

First,

You have to convert any mixed numbers to fractions and reduce the fractions as much as possible.

51/10 x 1/3

Then,

Multiply the two numbers using the 'Fraction formula."

51/30

Lastly,

Simplify 51/30 back to a mixed number.

1 7/10

Step-by-step explanation:

We know that a linear equation with two variables has infinitely many ordered pair solutions that form a line when graphed. A linear inequality with two variables, on the other hand, has a solution set consisting of a region that defines half of the plane.

Answer:

which is $160

Step-by-step explanation:

2,000 of 8%

= 160

2,000 divided by 8%

In the next 6 years she will pay only: "R$ 160,00"

Nos próximos 6 anos ela ppagará apenas: "R$ 160,00"

[tex]8[/tex]%[tex]de[/tex][tex]\frac{8}{100} .2000 = \frac{8.2000}{100} = \frac{8.20}{1} = \frac{160}{1} = 160[/tex]

Answer: Its A. decagon

Answer:

A

Step-by-step explanatio

Answer:

A and C

Step-by-step explanation:

5/7 x 610 = 435.7142857 or 435.7

3/2 x 610 = 915

2/3 x 610 = 406.6666667 or 406.7

5/4 x 610 = 762.5

A and C are correct because they are the only ones with an answer less than 610.

Answer:

i was just doing a test on this

Step-by-step explanation:

subtract 18.4 from both sides

Answer:

 A. 74 cm

Step-by-step explanation:

First, we break the rhombus down into similar shapes,

The area of 2 triangles = The area of a square

So we take the triangle from the left and combine it with the triangle on the right, it should make a rectangle, Then calculate the area of the rectangle,

10 multiplied by 5 =50

Thats the area of rectangle 1

Rectangle 2

3 multiplied by 6 = 18

Triangle

4 times 3 divided by 2 = 6

Thus

6 + 18 + 50  = 74

Answer:

A = 1/2(10×6)

A = 1/2(16+11)×(7)

Step-by-step explanation:

The height is the hardest to find for each, so to find which goes where youd need to find what's straighter.

Like the triangle, to find the height youd need to flip it around to see what measurement is the straightest.

Same goes for the height of the Trapezoid

Answer:

  undo what is done to the variable

Step-by-step explanation:

As with any "solve for" problem, it is a good idea to take a look at what is being done to the variable you're solving for.

Starting "as is"

Here, the value 2.5 is added to it, and the sum is multiplied by -5 (which we notice is negative).

In general, you want to "undo" what is done to the variable — in reverse order. What was done:

If we adopt that strategy, it means we first need to undo multiplication by -5. That is, we must either (a) multiply both sides by -1/5, or (b) divide both sides by -5. Either choice will require that the sense of the comparison be reversed, so you will have ...

  ( ) < (x + 2.5)

After that, you need to "undo" the addition of 2.5. That is accomplished by adding -2.5 to both sides of the equation.

__

Simplifying first

For many problems that have fractions and/or parentheses, it can work well to eliminate both before you start with your "undo" strategy. Here, a first step can be to simplify the inequality, eliminating parentheses. This means you will use the distributive property to multiply each term inside parentheses by the (negative) factor outside.

Having done that, you find the "what was done to the variable" list is slightly different:

As a consequence the "undo" steps are slightly different. Addition is still reversed by adding the opposite. Multiplication is still reversed by multiplying by the reciprocal, or by division (same thing).

As before, (and as always), what you do to one side of the inequality, you must also do to the other side. If multiplication or division by a negative number is involved, the comparison symbol must be reversed.

_____

About Negative Multiplication/Division

Above, we have noted that multiplication or division by a negative number requires reversal of the comparison symbol. For example, ...

  starting with -1 > -2

multiplying both sides by -1 gives ...

  ending with 1 < 2

__

When the (only) variable term has a negative coefficient, there is another strategy you can use that does not require the comparison to be reversed. You can add the opposite of that term to both sides of the inequality. For example, ...

  starting with -5x < -38

we can add 5x to both sides to get ...

  0 < -38 +5x . . . . . now the variable has a positive coefficient

This lets us proceed with the solution without worrying about the sense of the inequality. (Note that the variable will be "greater than" some value.)

More about solving strategy

The rules that make Algebra possible are the rules of equality. If you look them up, you may find separate versions for addition, multiplication, subtraction, division. If you realize that subtraction is a form of addition, and that division is a form of multiplication, there are really only two—and those can be simplified to ONE RULE: always do the same operation on both sides of the equal sign. The same rule applies to inequalities. You will stay out of trouble if you remember and follow this rule. (There are many "shortcut" versions that go by names like "cross-multiply" and others. They are basically this rule with some steps not shown.)

When it comes to applying functions to inequalities, you need to consider carefully whether the function preserves the ordering relationship (>, ≥, <, ≤). Some functions do not, or have different behavior in different domains, so paying attention is required. Multiplication by a negative number is just the tip of the iceberg here.

Answer:

r = - 2

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to [tex]\frac{1}{7}[/tex]

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 9, - 3) and (x₂, y₂ ) = (- 2, r)

m = [tex]\frac{r+3}{-2+9}[/tex] , that is

[tex]\frac{r+3}{7}[/tex] = [tex]\frac{1}{7}[/tex] ( cross- multiply )

7(r + 3) = 7 ( divide both sides by 7 )

r + 3 = 1 ( subtract 3 from both sides )

r = - 2
