What Is The Value Of X?

Answers

Answer 1

Answer:

x = 9

Step-by-step explanation:

12^2+x^2 = 15^2

==> x = 9

Answer 2

Answer:

9

Step-by-step explanation:

x = [tex]\sqrt{c^{2} - a^{2} }[/tex]

x = [tex]\sqrt{15^{2} - 12^{2} }[/tex]

x = [tex]\sqrt{225 - 144}[/tex]

x = [tex]\sqrt{81}[/tex]

x = 9

Answer:

[tex]2(x+2)/x+1[/tex]

Step-by-step explanation:

Answer:

2( x +2 )

x+1

Step-by-step explanation:

to add or subtract expressions expand them to make their denominators the same, multiply 1 time [tex]\frac{x-2}{x-2}[/tex]

since [tex]\frac{x}{x-2}[/tex] and [tex]\frac{x-2}{x-2}[/tex] have the same denominators add them by adding their numerators

combine x + x -2

factor [tex]x^{2}[/tex] - 4

to add or subtract expressions expand them and multiply by 1

have same denominator add them by adding their numerators

do the multiplications in 3 + ( x-2 )(x+2)

combine like terms in 3 + [tex]x^{2}[/tex] + 2x - 2x -4

divide [tex]\frac{2x-2}{x-2}[/tex] by [tex]\frac{-1 + x^{2} }{(x-2)(x+2) }[/tex] multiplying [tex]\frac{2x-2}{x-2}[/tex]

What is the proportion of 36 / x equals 8/7

Answers

Answer:

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

36/x=8/7

x times 36/x=x times 8/7

Cancel multiplied terms that are in the denominator

cancel both x’s for you should have 36=x times 8/7

Combine multiplied terms into a single fraction

36=8x/7

Multiply all terms by the same value to eliminate fraction denominators

36=8x/7 so you multiply 7 times 36=7 times 8x/7

so you simplify so you get 252=8x

then you Divide both sides of the equation by the same term

252=8x     252/8=8x/8 so you get 63/2

so your final answer is x=63/2

Need to find measure of m, p

Answers

Step-by-step explanation:

2p-5=p+5

p=10°

2m=10

m=5

Answer:

m = 5

p = 10

Step-by-step explanation:

In triangle HIJ,

IH = IJ.. (given)

Therefore,

2m = 10

m = 10/2

m = 5

IK is angle bisector of triangle HIJ.

So,

(2p - 5)° = (p = 5)°

2p - 5 = p + 5

2p - p = 5 + 5

p = 10

Thor and Rusty bought snacks for a party. Thor bought 4 bags of chips and 3 bottles of soda for $10.52. Rusty bought 3 bags of chips and 2 bottles of soda for $7.61. How much did the bags of chips each cost? How much did the bottles of soda each cost?

Answers

Answer:

Chips= $1.79

Soda= $1.12

Answer:

chips:  $1.79

soda: $1.12

Step-by-step explanation:

x = chips cost

y = soda cost

4x + 3y = 10.52

3x + 2y = 7.61

i used the elimination method by multiplying the first equation by -2

and the second equation by 3

-8x - 6y = 21.04

9x + 6y = 22.83

x = 1.79

solve for 'y':

3(1.79) + 2y = 7.61

5.37 + 2y = 7.61

2y = 2.24

y = 1.12

Score with a questions wrong:

Pls help fast 80 points

Answers

Answer:

Score with 5 questions wrong = 40 points

x questions wrong = 50 - 2x points

Score with a question wrong = 48 points

Step-by-step explanation:

Total points = 50 points

Points per question = 2 points

Number of questions = Total points / Points per question

= 50/2

= 25 questions

What would be Nasim's test score (out of 50) if he got 5 questions wrong

= Total points - 5 questions * 2 points

= 50 - 5(2)

= 50 - 10

= 40 points

Score with 5 questions wrong = 40 points

What would be his score if he got x questions wrong?

= Total points - x questions * 2 points

= 50 - x(2)

= 50 - 2x

Where x = number of questions

x questions wrong = 50 - 2x points

Score with a question wrong

= Total points - 1 questions * 2 points

= 50 - 1(2)

= 50 - 2

= 48 points

Score with a question wrong = 48 points

Step-by-step explanation:

Ok, so all we have to do is multiply 8 * 3/4, because each child needs 3/4 of the sandwich, and there are 8 of them. The easiest (My opinion) way to do this is by turning 8 into a fraction. Turning whole numbers into fractions is really simple, just slap a /1 under them to make them a fraction. And so, our fraction is 8/1. Now, all we have to do is multiply the top part of the fraction, and then the bottom part of the fraction. So, 8 * 3 = 24, and 1 * 4 = 4. So, just put 24/4 as an answer. But, wait! We have to simplify it! 24 divided by 4 is 6, so 6 is our final answer.
