15/1 x 20/7 dont have a calculator

Answer:

y=3

Step-by-step explanation:

Answer:

y = 3

Step-by-step explanation:

first the slope:

[tex]m = \frac{3-3}{-7-5} =0[/tex]

The equation

[tex]y-3=0(x-(-7))\\y-3=0[/tex]

[tex]y=3[/tex]

The line is parallel to the "x" axis, has no slope.

Hope this helps

Answer :: 7

Explanation ::

Okay, I'm going to stretch this explanation long so people can understand! Hopefully this helps :) I will also provide a shorter explanation so if people want to find out how to do it quicker without details to help you understand better, they can read the shorter explanation!

Equation provided from the info :: (x * 2) + 1 = 15

We need to find out what number is the x. First of all, one way to do it is do the equation backwards. And the operators will be the opposite too, for example addition is the opposite of subtraction and multiplication is the opposite of division. Now once we flip the equation it should look like this:

(15 - 1) / 2 = x

Let's break the equation apart so it's easier to work with. Remember, the rule PEMDAS. Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. Why I put "and" between some words, is because they are the same level and you should go left to right from the equation. So the equation in parentheses is (15 - 1). So we just have to solve it! The answer is 14, which is an even number, so we don't have to fiddle with decimals. But if you want to know how to divide an odd natural number, feel free to comment on this answer! The equation should look like this:

14 / 2 = x

Now, all we have to do now is divide 14 in half! As someone who memorised their whole multiplication and division table, it's easy for me to figure it out. But if you haven't, try using addition! All you have to do is count up your numbers.

1 + 1 = 2

2 + 2 = 4

3 + 3 = 6

4 + 4 = 8

5 + 5 = 10

6 + 6 = 12

7 + 7 = 14!

So now we know 14 / 2 is 7. Sorry if this is too easy, I'm just giving attention to some who learn slowly, which is absolutely alright! So now we have our 2 answers. The equation now looks like this:

14 / 2 = 7.

Well we now know what the x is, and if you want to make sure it's the correct answer just flip the equation!

(7 * 2) - 1

7 * 2 = 14

14 - 1 = 15

Your answer is the same one provided, so the number is 7!

- short explanation -

The equation with the numbers provided is (x * 2) + 1 = 15

Let's flip the equation so it's easier! It should look like this:

(15 - 1) / 2 = x

Now all we have to do is solve it!

15 - 1 = 14

14 / 2 = 7

So our answer is 7! To check if the answer is correct, just re-do the unflipped equation!

(7 x 2) + 1 = ??

7 x 2 = 14

14 + 1 = 15

15 is the answer given in the text, so 7 is the correct answer.

Answer:

The answer is 37.

Step-by-step explanation:

Step 1: To find the output, k, we need to substitude 3 into the equation for t.

Step 2: k = 13t - 2

k = 13 x 3 - 2

= 39 - 2

= 37

Step 3: When the input is 3, the output is 37.

Answer:

D: difference between Shelly and Terrence total points

Step-by-step explanation:

We know the area of a circle is

[tex]\pi {r}^{2} [/tex]

That is when the cricle is 360 degrees full, so another formula is

[tex] \frac{360}{360} \pi {r}^{2} [/tex]

If we the find the area of the sector with angle x, then that formula will be

[tex] \frac{x}{360} {\pi}r^{2} [/tex]

Answer:

The area of a sector is part of an area of the entire circle. Determine the fraction of the circle that the sector represents and multiply it by the area of the circle.

Answer:

Logan: 9

Ethan: 14

Step-by-step explanation:

Let Ethan = e

Let Logan = l

1) We can set up two equations and solve them simultaneously.

e + l = 23

5 + l = e

1.1) To solve these equations, we can either use substitution or elimination.

5 + l + l= 23

2l = 23 - 5

2l = 18

l = 18/2

l = 9

2) Plug the result of l into one of the two equations above.

5 + 9 = e

14 = e

Answer:

f(g(x)) = 9x² + 15x + 2

Step-by-step explanation:

Solving f(g(x))

Answer:

[tex]f(g(x)) = 9x^2 + 15x + 2[/tex]

Step-by-step explanation:

Step 1:  State the equations

[tex]f(x) = x^2 + 5x + 2[/tex]

[tex]g(x) = 3x[/tex]

Step 2:  Insert the equation and solve

[tex]f(g(x)) = (g(x))^2 + 5(g(x)) + 2[/tex]

[tex]f(3x) = (3x)^2 + 5(3x) + 2[/tex]

[tex]f(3x) = 9x^2 + 15x + 2[/tex]

[tex]f(g(x)) = 9x^2 + 15x + 2[/tex]

Answer:  [tex]f(g(x)) = 9x^2 + 15x + 2[/tex]

Your median is 40

Step-by-step explanation:

Answer:

Answer are in the steps.

Step-by-step explanation:

Most of the problems is parallelogram some angles are the same. 2 angles add up to 180° are known as supplementary angles also known as linear pair.

#1:

<1 = 148° , <2= 32° , <3 = 148° , <1 = 32° , <5 = 148° , <6 = 32° , <7 = 32°

#2: All of them are 90° because of linear lines that add up to 180° / parallelogram.

#3: If <1 = 130°, then <8 = 148°.

Because Parallelogram <1 and <8 transversal.

#4 If <5 = 53° , then <3 = 127°

Because <5 = <4 so <5 + <3 = 180°

#5 If <7 = 71° , then <3 = 109°

Because <7 + <3 = 180°

#6 If <4 = 65° , then <6 = 115°

Because <5 = <4 so <4 + <6 = 180°

Answer:

(a) 1,028,160

(b) 8,568

Step-by-step explanation:

(a)

[tex]18 \times 17 \times 16 \times 15 \times 14 = 1028160[/tex]

(b) 18! / (5! 13!) =

[tex] \frac{18 \times 17 \times 16 \times 15 \times 14}{5 \times 4 \times 3 \times 2 \times 1} = 8568[/tex]

Answer:

r = 728   ( there might be an easier way! )

Step-by-step explanation:

w/r = 3/8       then   w = 3/8 r

b/w = 2/7       b = 2/7 w     sub in the above equation  b = 2/7 (3/8 r) = 6/56 r

r + w + b = 1079

r + 3/8 r + 6/56 r = 1079

  r = 728

answer is 1 1/2

Answer:

raju is 20 years old while the father is 40 years old

Step-by-step explanation:

present : lets assume raju is x years old so the father will be 2x

after 10 yrs raju will be x+10 yrs while the father will be 2x+10 yrs

therefore :

(x+10)+(2x+10)=80

liketerms together

x+2x+10+10=80

3x+20=80

3x=80-20

3x=60

simplify

x=20 so raju is 20 years old now and the father since he is twice the age of his son he is 40 years old
