find the value of x pls help

Answer:

$86.36

Step-by-step explanation:

Tax: 7%, or 0.07

Tip: 20%, or 0.2

Substitute the values:

Tip: 68 * 0.07 = 4.76

Tip: 68 * 0.2 = 13.6

Just the meal cost: 1 * 68 = 68

Add these all together

4.76 + 13.6 + 68 = 86.36

Thus, the total cost of the meal would be $86.36

Answer:

X=180-100

=80 is the answer

Answer:

$45.90

Step-by-step explanation:

Multiply without the decimal points, then put the decimal point in the answer: 85 x 54 = 4590

8.5 has 1 decimal place

5.4 has 1 decimal place

Therefore, the answer has 2 decimal places

= 45.90

Refine: 45.9

The answer is 45.9

Answer: yes 3/4 is greater

converting both fractions to decimals. The decimal 0.75 is bigger than 0.5, so 3/4 is bigger than 1/2.

Answer:

3/4 is greater than 1/2.

Step-by-step explanation:

One way to compare fractions is by making them have the same denominator.

You can do this by finding the least common denominator (LCM).

First, list the multiples of each denominator.

4: 4, 8, 12, 16, 20

2: 2, 4, 6, 8, 10

As you can see, 4 is the LCM.

Now, change the fractions to where they denominators of 4.

**WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MUST ALSO MULTIPLY IT BY THE NUMERATOR.**

[tex]3/4*1/1=3/4[/tex] (STAYS THE SAME)

[tex]1/2*2/2=2/4[/tex]

Now, as you can see, 3/4 is larger than 2/4.

Therefore, 3/4 is larger than 1/2.

Answer:

3 units

Step-by-step explanation:

By intersecting chords theorem:

[tex] AE \times EB = CE \times ED[/tex]

[tex] \therefore 3 \times 4= x \times (x+1)[/tex]

[tex] \therefore 12= x^2 +x[/tex]

[tex] \therefore x^2 +x-12=0[/tex]

[tex] \therefore x^2 +4x-3x-12=0[/tex]

[tex] \therefore x(x +4)-3(x+4)=0[/tex]

[tex] \therefore (x +4)(x-3)=0[/tex]

[tex] \therefore (x +4)=0, \: (x-3)=0[/tex]

[tex] \therefore x=-4, \: x=3[/tex]

Since, the value of x can not be negative.

[tex] \therefore x\neq - 4[/tex]

[tex] \implies x = 3[/tex]

[tex] \implies CE = 3[/tex]

Answer:

Hay 32 pollitos en total.

Step-by-step explanation:

Para contestar a la pregunta planteada se debe realizar el siguiente razonamiento matemático:

Casas = 2

Gallineros = 2

Cercados = 2

Gallinas = 2

Pollitos = 2

2 x 2 x 2 x 2 x 2 = X

4 x 2 x 2 x 2 = X

8 x 2 x 2 = X

16 x 2 = X

32 = X

Por lo tanto, hay 32 pollitos en total.

Answer:

The sum of x and y is 8.

Step-by-step explanation:

x+2y=10

x-2y=2

------------

2x = 12, so x = 6.  Substituting 6 for x in the 2nd equation, we get:

6 - 2y = 2, or

4 = 2y, or y = 2.  The solution is therefore (6, 2).

The sum of x and y is 6 + 2 = 8 (answer)

Answer:

6 + 2 = 8

Step-by-step explanation:

[tex]x + 2y = 10 \\ + \\ x - 2y = 2 \\ = \\ 2x = 12 \\ x = 6 \\ 6 + 2y = 10 \\ 2y = 4 \\ y = 2 \\ x + y = 6 + 2 = 8[/tex]

Answer:

68:76.5

Step-by-step explanation:

create the ratio 68/x=8/9, then simplify the side you can so get 68/x=.8888... then multiply both sides by x to get rid of the fraction, 68=.8888...x. now divide both sides by .8888... to get x by itself, 76.5=x

Answer:

i guess your new grade would be 88%. If you past 100%, you might pass for that grade. Even if you get a 90%, you'll still be able to pass.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) y = 50x + 2500

2) y = 200x + 1000

if we build a system with the two equations, we have:

50x+2500 = 200x + 1000

150x = 1500

x = 10

y = 2000 + 1000 = 3000

3) 10

Answer:

A=2.2

Step-by-step explanation:

PYTHAGOREAN THEOREM:

a^2+b^2=c^2

STEP 1:

Lets put in the given number into the Theorem.

x^2+ 2^2= 3^2

I put x in the "a" place because there is no Number that goes into there, so we put in a variable.

STEP 2:

We find the numbers, which are

x^2+4=9

STEP 3:

We then subtract by 4 from both sides, (We do this because x is not the Hypotenuse)

After subtracting from both sides we have

x^2=5

STEP 4:

Once we have that, we have to find the square root of 5 which is  2.23606798

STEP 5:

Since you say to round to the nearest tenth, we get 2.2

TIP: If the answer didn't have to be rounded to the nearest tenth the answer would've been: [tex]x=\sqrt{5}[/tex]  Which is the same as 2.23606798.

Answer:

y= -1/4x+2

Step-by-step explanation:

y=mx+b is the slope intercept form.

We first must isolate y by adding 1/2x on both sides.

-2y=-4+1/2x

next we multiple by -1/2 to get rid of the -2

y=2-1/4x

y=-1/4x+2

The  difference between two positive numbers is 7 and the difference between these  cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,

So,

Let the number be n and m

A = n × m = nm

B = n² + m² = (n + m)²

Now

n³ - m³ = 805

(n - m) (n² + m² + nm) = 805

Since difference is 7

7 × n² + m² + nm = 805

n² + m² + nm = 805/7

n² + m² + nm = 115

(n² + n) + (m² + m) = 115

A + B = 115

Now

On squaring the first eq.

(n - m)² = (7)²

(n - m)² = 49

B - 2A = 49

Now

A + B - B + 2A = 115 - 49

A + 2A = 66

3A = 66

A = 66/3

A = 22

By using 2

B - 2(22) = 49

B - 44 = 49

B = 49 + 44

B = 93

A - B = 22 - 93 = -71
