13/2 x 21/13 = 273/26 = 10 1/2
The answer is C, 10 1/2.
6 1/2 = 13/2
1 8/13 = 21/13
13/2 * 21/13 = 273/26
273/26 = 10 1/2

Answers
Answer:
x = 1 ± [tex]\sqrt{5}[/tex]
Step-by-step explanation:
x(x - 2) = 4
Multiply x on the left side by foil.
[tex]x^{2}- 2x = 4[/tex]
Subtract 4 on both sides.
[tex]x^{2} -2x-4=0[/tex]
Now, the quadratic formula.
x = (-b ± [tex]\sqrt{b^{2} - 4ac }[/tex]) / 2a
Using the standard form equation.
Ax² + Bx + C = 0
(1)x² - 2x - 4 = 0
A = 1
B = -2
C = -4
x = (-(-2) ± [tex]\sqrt{(-2)^{2}-4(1)(-4) }[/tex]) / 2(1)
x = (2 ±[tex]\sqrt{4+16}[/tex] ) / 2
x = (2±[tex]\sqrt{20}[/tex])/2
x = (2±2[tex]\sqrt{5}[/tex])/2
x = 1 ± [tex]\sqrt{5}[/tex]

O {4 - V8,4 + V8}
O {4 - V3, 4 + V3}
Answers
Answer:
first option
Step-by-step explanation:
x² - 8x = 3
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 3 + 16
(x - 4)² = 19 ( take square root of both sides )
x - 4 = ± [tex]\sqrt{19}[/tex] ( add 4 to both sides )
x = 4 ± [tex]\sqrt{19}[/tex]
then
x = 4 - [tex]\sqrt{19}[/tex] , x = 4 + [tex]\sqrt{19}[/tex]

Answer:
1st and 6th option, 35 adult tickets
Step-by-step explanation:
So we know adult tickets are x and children tickets are y.
The total number of tickets is 57, so
x + y = 57
The adult tickets are worth 6 and the children's tickets are worth 2.50.
The total cost is 265.
6x + 2.5y = 265
Now, the system of equations.
6x + 2.5y = 265
-6x - 6y = -342
-3.5y = -77
y = -77/-3.5
y = 22
Plugging y back in
x + 22 = 57
x = 35 adult tickets sold
* $265 worth of tickets were sold
* Adult tickets cost $6
* Child tickets cost $2.50
* 57 tickets were sold
To Find ↷Let x represents the number of adult tickets sold and y as the number of child ticket sold
Which squations equation represents the scenerio? select 2 options
Answer ↷x ⇢No. of adult tickets soldy⇢No. of child ticket soldso ,the equations would be

⤿ 6x + 2.5y = 265 ✓
Solution↷x + y = 57.....(1)
6x + 2.5y = 265.....(2)
Multiplying equation 1st by 6
we get,
6x + 6y = 342 ...(3)
subtracting equation (3) by equation (2)
we get,
6x + 6y = 342
-6x + 2.5y= 265

The computation of the power shows that Natasha was right as the value gotten is 295hp.
How to calculate power?From the information given, t is given as 5.825 to the cube root of w/p.
In this case, the value of p will be:
p = w/t³(5.823)³
p = 3590(5.823)³ / (13.4)³
p = 708828.13/2406.104
p = 295hp

What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
Grace has a segment with endpoints C (3, 4) and D (11, 3)
And, It is divided by a point E such that CE and DE form a 3:5 ratio.
Hence, We get;
The coordinates of E is,
E = [ ( 3× 11 + 5 × 3)/(3 + 5) , (3×3 + 5 × 4)/(3 + 5) ]
= [ (33 + 15)/8 , (9 + 20)/8 ]
= *(48/8 , 29/8)
= (6 , 3.625)

Solve using log. I have no idea how to use log so please explain how to use it.
Answers
Answer:
11.776
Step-by -step explanation:
Here we are given a equation which is ,
[tex]\rm\longrightarrow 10^{x-10}-8=51.7 [/tex]
And we would like to solve this using logarithms , so firstly add 8 on both sides , we get ;
[tex]\rm\longrightarrow 10^{x-10}= 51.7+8 [/tex]
Simplify,
[tex]\rm\longrightarrow 10^{x-10}= 59.7 [/tex]
Now take log to the base 10 on both sides ,
[tex]\rm\longrightarrow log_{10}10^{x-10}=log_{10}(59.7) [/tex]
Recall that [tex]log\ m^n = n\ log m [/tex] .So ;
[tex]\rm\longrightarrow (x-10)(log_{10}10=log_{10}(59.7) [/tex]
Again recall that [tex] log_a a = 1[/tex] .So ; here [tex]log_{10}10[/tex] becomes 1 .
[tex]\rm\longrightarrow (x -10)1 = log_{10}59.7 \\ [/tex]
[tex]\rm\longrightarrow (x-10)= log_{10}(59.7)[/tex]
And the value of log 59.7 = 1.7759 . So on substituting this value , we have ;
[tex]\rm\longrightarrow x -10 = 1.7759 [/tex]
Add 10 to both sides ;
[tex]\rm\longrightarrow x = 10+1.7759 [/tex]
Simplify,
[tex]\rm\longrightarrow \underline{\underline{\red{\rm { x = 11.7759 \approx 11.776}}}}[/tex]
