Put the following equation of a line into slope-intercept form, simplifying all fractions. 5 x + 2 y = 10

Answers

Answer:

y = -5/2x + 5

Step-by-step explanation:

slope intercept form: y = mx + b

5x + 2y = 10 ------- subtract 5x on both sides

2y = -5x + 10 ------- divide 2 on both sides

y = -5/2x + 5

The price of a notebook has dropped to $3.45 today. Yesterday's price was $3.95. Find the percentage decrease. Round your answer to the nearest tenth of a percent.

Answers

10%

Step-by-step explanation:

($3.95 - $3.45)/($3.95) × 100%

= ($0.50)/($3.95) × 100%

= 50/3.95 %

= 5000/395 %

= 1000/79 %

= 12,65 % → Round to the nearest tenth

can you add fractions with unlike denominators? if so what do you have to do.

Answers

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.

To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

What is the answer to this math question

Answers

Answer:

11

Step-by-step explanation:

1.80m + 0.6s = 12.00

[substitute the value of m into the equation]

1.80×(3) + 0.6s = 12

5.4 + 0.6s = 12

[make s the subject of the formula]

0.6s = 12 - 5.4

0.6s = 6.6

[divide both sides of the equation by 0.6]

0.6s / 0.6 = 6.6 / 0.6

s = 11

To prove that 11 is correct

[substitute the value of m and s into the equation]

1.80m + 0.6m = 12.00

1.80×(3) + 0.6×(11) = 12.00

5.4 + 6.6 = 12.00

12.00 = 12.00

What is the equation, in slope-intercept form, of the line that passes through
the point (7, 2) and is parallel to y= -2x+1?

Answers

Answer: y  = - 2 x  + 16Step-by-step explanation:

Find the slope of the parallel line

(7, 2) and is parallel to y= -2x+1?

When two lines are parallel, they have the same slope.  

                ⇒  if the slope of the given line is = - 2      

                     then the slope of the parallel line (m) = - 2

Determine the equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  

                              ⇒  y - 2  =  - 2 (x - 7)                                  

                           

We can therefore write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:  

                     since   y - 2  = - 2 (x - 7)  

                           ∴   y  = - 2 x  + 16

-35 + ( -31 ) + ( -39 )

Answers

Answer:-105

Step-by-step explanation:

Answer:

Ok so, let's break it down

Step-by-step explanation:

-35+(-31)

Let's ignore the parenthesis and the - symbol

35+31

That would equal 66, so now we add back the - symbol which will make it -66

So we already have -66, so now we have -66+(-39)

We do the same thing we did with -35+(-31)

So we have 66+39

That makes -105

So your answer is -105

Step-by-step explanation:

PLEASE HELP ME ASAP.

Answers

Step-by-step explanation:

anything whole or complete is designated as 100%.

what is x% of that whole ?

well, we need to multiply the whole with the same factor we need to multiply 100 with to get x.

100×f = x

f = x/100

whole × f = x% of the whole

so, when we are looking for 5%, what did that mean ?

it means that x = 5, and f = 5/100.

therefore, 5% of $13 is

13 × 5/100 = 65/100 = 0.65

so,

basic cost = $13

tax rate = 5%

tax amount = $0.65

and

basic cost = $13

tax amount = $0.65

total cost = 13 + 0.65 = $13.65

as 5/100 = 0.05

we have seen that the tax amount is simply $13×0.05

and when we add the tax amount to the basic cost, we need to add $13×1 (basic cost) to the $13×0.05 (tax amount), and we get as total

total cost = $13×(1+0.05) = $13×1.05 = $13.65

so, the decimal factor we can use directly without going through all the detail above is : 1.05

and he has a package of cheese with 24 slices. How many sandwiches can Deion make before
he runs out of cheese?
answer quickly please!

Answers

Answer:

12 sandwiches

Step-by-step explanation:

We know that Deion has 24 cheese slices, and uses 2 slices per sandwich, so in order to find how many sandwiches he can make, we can divide the total number of cheese slices by the number used to make a sandwich:

24 / 2 = 12

Therefore, Deion can make 12 sandwiches before he runs out of cheese.

Answer: 2.5 feet

Step-by-step explanation:

A 30-60-90 triangle is a special right triangle in which the sides all have a fixed relationship with each other.  We only need to know one side to calculate the other two.

Make the side opposite the 30° angle x, then

The side opposite the 60° angle is x*√3The side opposite the 90° angle is 2x

The side opposite the right angle is 5ft, therefore:

2x = 5

x = 2.5ft, the side opposite the 30° angle

Then x*√3 is the third side:

(2.5)*(1.442) = 3.605 feet

convert 150.55 decimal to binary​

Answers

10010110.10001100110011001101

Answer:

10010110 . 100011₂

Step-by-step explanation:

A real number consists of two parts.

That is, ( 1 ) Integer part     ( 2 ) fractional part

Let us take the given number as an example.

Here, 150 . 55 ←  fractional part

           ↑        

(integer part)

So, to make such a decimal number into a binary number you have to use a method like this.

First, you have to make the integer part a binary number.For that, you have to divide the integer part by 2 until it gets zero.Important thing is you have to write the remainders in each step.After that, you have to write the remainders from bottom to top.Now, let us consider the fractional part.To convert the fractional part into a binary number you have to multiply only the fractional part in each step by two.There you'll get an integer part before the fractional part. In this step, you have to write the integer part from top to bottom.

Let us solve it now.

Integer part

2 |150  

2 |75    - 0

2 | 37   - 1

2 | 18     - 1

2 | 9      - 0

2 | 4       - 1

2 | 2       - 0

2 | 1         - 0

    0         - 1

∴ 150 ⇒ 10010110₂

Fractional part

   | . 55 × 2

 1 | . 10 × 2

0 | . 2 × 2

0 | . 4 × 2

0 | . 8 × 2

 1 | . 6 × 2

 1 | . 2

As this fractional part not getting the zero even we multiply by 2 continuously, we have to write an approximate value for this.

150.55 ⇒ 10010110 . 100011₂

If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.
