What is the solution to the following system of equations y=2x-4 Y=x

Answer:

x = 10°

Step-by-step explanation:

8x + 50 = 130 (corresponding angles are equal)

8x = 80

x = 10°

Answer:

$5.00 ; no

Step-by-step explanation:

Given that:

135 / 360 = 0.375

90 / 360 = 0.25

135/ 360 = 0.375

X ___ 5 _____10 _____ 0

P(x): _0.25___0.375___0.375

Expected value :

ΣX*p(X) :

5(0.25) + 10(0.375) + 0(0.375)

1.25 + 3.75 + 0

= $5

b) If you have to pay $10 to play, is it a fair game?

For the game to be fair :

Amount paid = Expected winning

$10 ≠ $5

Since, amount paid is greater than expected winning, then the game is not fair

Answer:

x = -4

Step-by-step explanation:

Rearrange equation so that like terms are on one side and the numbers are on the other.

2x - x = 3 - 7

x = -4

Answer:

x=-10

Step-by-step explanation:

2x-x+7=x-x-3

x+7-7=-3=7

x=-10

Answer: Mikes home street address number = 52233

Step-by-step explanation:

We need to make a 5 digit number such that

Two digits have values of 50,000 and 200 .

The digits in the ones place is 3 .

Now number is like 50,000 +x + 200 + y + 3  (ten thousand >  thousand > Hundred > tens > ones )

Need values for :  thousands place and tens place

The value of each of the other digits is ten times the value of the digits on its right .

thousands place value (x)= 200 x 10 = 2000

tens place value (y)= 3 x 10 =30

Required number =  50,000 +2000 + 200 + 30+ 3  = 52,233

∴Mikes home street address number = 52233

Answer:

9 students

Step-by-step explanation:

Let x be the number of students taking only Physics and Chemistry

Number of students :

All 3 sciences = 9

Only physics = 12

Both Physics and Biology( without Chem ) = 24 -9 = 15

15+ 9 + 12+x = 45 , since Physics is compulsory

36 + x = 45

x = 45 - 36

x = 9

Hope it helps :)

= p , weight of full pail

Answer:

m = -2

Step-by-step explanation:

The points I will be using are (-3, 6) and (0,0).

To find the slope, you sub these points into the slope formula - rise over run.

Answer:

The slope is -2

Step-by-step explanation:

to get from (0,0) to (-3,6) you rise 6 and go left 3. Then 6÷-3= -2.

Step-by-step explanation:

the missing term is 5

Hi there !

12x² - 75 =

= 3(4x² - 25)

use formula a² - b² = (a - b)(a + b)

= 3(2x - 5)(2x + 5)

= 3(2x + 5)(2x - 5)

the missing term is 5

Good luck !

Answer:

31.25miles per gallon

Step-by-step explanation:

Distance traveled  = 100miles

Quantity of gasoline used  = 3.2gallons

Unknown:

Rates of distance traveled to fuel used = ?

Solution:

 The rates of distance traveled to fuel used is given as;

   Rates  = [tex]\frac{distance traveled}{fuel used }[/tex]

Input the parameters and solve;

   Rates  = [tex]\frac{100}{3.2}[/tex]   = 31.25miles per gallon

Answer:

Step-by-step explanation:  -49 -(-66)

= -49 + 66  ( here (-) and (-) is multiplied, therefore the final answer is +)

= 17                ( here when - and+ sign comes subtract them as we do normally, then mark the final answer with the greater number's sign, here the greater number is 66, so in the final answer we mark +17 or 17)

Answer:

4^1 + 17 = 21 , which is divisible by 3. 4^k + 17 and 3 * 4^k are both divisible by 3, so 4^k + 17 + 3 * 4^k is divisible by 3 as well. 3 * (4^n + 17) would be divisible by 9

Answer:

x = -4 2/13

x = -4.15384615385

x = -54/13

(they are all the same, just in different formats)

Step-by-step explanation:

(5/3x) + 6 = (2/9)x

first, make all "x"s have a common denominator

(5/3) = (15/9)

so

(5/3)x = (15/9)x

(15/9)x + 6 = (2/9)x

solve using inverse operations

(15/9)x + 6 = (2/9)x

-(2/9)x         -(2/9)x

(13/9)x + 6 = 0

            -6    -6

(13/9)x = -6

to get rid of the fraction, multiply the entire equation by the denominator

(13/9)x = -6

*9          *9

13x = -54

/13     /13

x = -4 2/13

x = -4.15384615385

x = -54/13

(they are all the same, just in different formats)
