this question is driving me nuts The rest says the right triangle​

Answer:

(5,-1)

Step-by-step explanation:

Since one of the equations gives x in terms of y , ie x = 1 - 4y

Then this can be substituted directly into the other equation.

→ 2(1 - 4y) + 7y = 3 → 2 - 8y + 7y = 3 → -y = 1 → y = -1

now, substitute y = -1 into x = 1 - 4y , to obtain x

→ x = 1 - 4(-1) = 1 + 4 = 5

Thus solution is (5 , -1 )

Answer:

2

Step-by-step explanation:

9-7=2

Answer:

x = 2

Step-by-step explanation:

Subtract 7 from both sides.

[tex]x+7=9\\\\x+7-7=9-7\\\\\boxed{x=2}[/tex]

Hope this helps.

Answer with step-by-step explanation:

For a figure or object that has rotational symmetry, the angle of turning during rotation is called the angle of rotation. Example: when a square is rotated by 90 degrees, it appears the same after rotation. So, the angle of rotation for a square is 90 degrees.

Answer:

i think its 64.66

Step-by-step explanation:

07x53=3.71

0.15x53=7.95+53=60.95+3.71=64.66

Answer:

$64.66

Step-by-step explanation:

find the amount of tax 53 x .07 = 3.71

find the amount of the tip 53 x .15 = 7.95

53 + 3.71 + 7.95 = 64.66

the anser is

x- 2 y =6

x- 2 y =6

Answer:

D

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The initial fee of $12 would be the y-intercept because no matter how many boxes of cards you buy, the fee stays the same. The slope would be $3.99 because that fee is charged per box. The 100 cards per box is extra information and not needed in the equation. D is the only logical choice.

Answer:

m=10

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    m/5+9-(11)=0

                 m

Simplify   —

                 5

  m          

 (— +  9) -  11  = 0  

   5

Adding a whole to a fraction

Rewrite the whole as a fraction using  5  as the denominator :

           9        9 • 5

   9 =  —  =  —————

            1           5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

m + 9 • 5                       m + 45

—————————  =  ——————

    5                                       5  

     (m + 45)    

 ———————— -  11  = 0  

          5

Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

             11          11 • 5

   11 =  ——  =  ——————

             1               5  

Adding up the two equivalent fractions

    (m+45) - (11 • 5)                                  m - 10

—————————————————  =  ——————

            5                                                          5  

    m - 10

 ——————  = 0  

        5

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

   m-10

 ———— • 5 = 0 • 5

      5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  m-10  = 0

Solve  :    m-10 = 0  

Add  10  to both sides of the equation :  

                     m = 10

m = 10

Answer:

[tex] x = 13.8 ft [/tex]

Step-by-step explanation:

Since it's a right triangle, apply pythagorean theorem.

The formula is given as a² + b² = c²

Where,

a = 3.7 ft

c = 14.3 ft

b = x

Plug in the values into the formula:

[tex] 3.7^2 + x^2 = 14.3^2 [/tex]

[tex] 13.69 + x^2 = 204.49 [/tex]

Subtract 13.68 from both sides

[tex] x^2 = 204.49 - 13.69 [/tex]

[tex] x^2 = 190.8 [/tex]

[tex] \sqrt{x^2} = \sqrt{190.8} [/tex]

[tex] x = 13.8 [/tex] (nearest tenth)

Answer:

10 1/3

Step-by-step explanation:

Convert mixed numbers into improper fractions (whole number × denominator + numerator)

25 2/3 and 15 1/3

25 × 3 + 2 = 75 + 2 = 77

Put the number over the same denominator

77/3

15 × 3 + 1 = 45 + 1 = 46

Put the number over the same denominator

46/3

77/3 - 46/3

They have common denominators so we can simply subtract the numerator values

77 - 46/3

31/3

To convert it back to a whole number, find how many times 3 fits into 31 evenly

It fits 10 times evenly with 1 remainding which looks like:

10 1/3

Answer:

40   mark Brainliest please

Step-by-step explanation:

15/40

Let the missing number be x .

Then :-

[tex] \frac{3}{8} = \frac{15}{x} [/tex]

[tex] 3 \times x = 8 \times 15[/tex]

[tex]3x = 120[/tex]

[tex]x = \frac{120}{3} [/tex]

[tex]x = 40[/tex]

The missing number is 40 .

Let us check it by doing cross multiplication :-

[tex]3 \times 40 = 15 \times 8[/tex]

[tex]120 = 120[/tex]

Hence proved the missing number is 40 .

[tex]therefore \: , \frac{3}{8} = \frac{15}{40} [/tex]

Answer:

A) The second day

B) 9/16 inches

A) Elsa reached farther on the second day because -1/16 > -5/8

B) To calculate this we must first put both fractions above the same denominator. We can then subtract the smaller one from the bigger one:

-1/16 - (-10/16) = 9/16

Elsa reached 9/16 inches farther on the second day then she did on the first.

Hope this helps and have a great day!

Answer:

3 3/4

Step-by-step explanation:

Answer:

Three and three fourths or 15/4

Step-by-step explanation:

This is about division of polynomials.

(f/g)(x) = (x + 1)/(2x + 3)

f(x) = 2x² - 3x - 9

g(x) = 4x² - 9

f(x) = 2x² - 3x + 6x - 9

Let's collect like terms;

f(x) = x(2x - 3) + 1(2x - 3)

Rewriting in factored form gives;

f(x) = (x + 1)(2x - 3)

g(x) = 4x² - 9

g(x) = 4x² + 6x - 6x - 9

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

Rewriting in factored form gives;

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

Thus;

(f/g)(x) = ((x + 1)(2x - 3))/((2x + 3)(2x - 3))

(f/g)(x) = (x + 1)/(2x + 3)

Step-by-step explanation:

Answer:

The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?

Let x = number of $3 tickets

Let y = number of $2 tickets

Total = quantity × value

Step-by-step explanation:

x + y = 350                    (equation 1)

3x + 2y = 950                 (equation 2)

Use Substitution Method

Isolate variable x in equation 1

x = 350 – y                     (equation 3)

Substitute equation 3 into equation 2

3(350 – y) + 2y = 950

1050 – 3y + 2y = 950

3y – 2y = 1050 – 950

y = 100

Substitute y = 100 into equation 1

x + 100 = 350

x = 250

Answer: 250 $3 tickets and 100 $2 tickets were sold.
