For most fractions, the beginning is indicated with "start fraction", the horizontal line is indicated with "over", and the end of the fraction is indicated by "end fraction". For the semantic interpretation, most numeric fractions are spoken as they are in natural speech. Also if a number is followed by a numeric fraction, the word "and" is spoken in between.

What are the solutions 2x^2 +7x=4

elena55 [62]

So your equation is $2x^{2} +7x = 4$ . You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now $4x + 7x = 4.$
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's $11x = 4$ right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be

0.36.

I hope I helped!

The scale on a city map is 3/4 inch represents 1/8 mile.How many inches per mile are represented by the scale on the map

Sonja [21]

3/4 inch represents 1/8 mile, that means:

1/8 mile represented by 3/4 inch

1 mile will be : (3/4) inch ÷ (1/8)

= 3/4 × 8/1 = 6

1mile will be represented by 6 inches

So on the map it is 6 inches per mile

How many of the first million positive integers share no common factors greater than 1 with 2020

Bingel [31]

9514 1404 393

Answer:

396,040

Step-by-step explanation:

Factors of 2020 are 2, 5, 101.

There are 1,000,000 / 1010 = 990 multiples of 2 and 5 and 101.

There are 1,000,000 / 505 -990 = 990 multiples of 5 and 101 only.

There are 1,000,000 / 202 -990 = 3,960 multiples of 2 and 101 only.

There are 1,000,000 / 10 - 990 = 99,010 multiples of 2 and 5 only.

There are 1,000,000 / 101 -990 -990 -3960 = 3,960 multiples of 101 only.

There are 1,000,000 / 5 -990 -990 -99,010 = 99,010 multiples of 5 only.

There are 1,000,000 / 2 -990 -3960 -99,010 = 396,040 multiples of 2 only.

So, the total number of multiples of any factor of 2020 is ...

990 +990 +3960 +99,010 +3960 +99010 +396040 = 603960

Then the number of integers in the first million that do not share any common factors greater than 1 with 2020 is ...

1,000,000 -603,960 = 396,040

Answer:

p(4)= 8

p(-9)=-5

Step-by-step explanation:

it is stated in the third point that the remainder of the division is zero

then p(x)/(x+4)=1

p(x)=(x+4)

p(4)=(4+4)

p(-9)=(-9+4)
