Answer:
video=$6.5
moive=$1
Step-by-step explanation:
5m+2v=18, 3m+8v=55
5m+2v=18
2v=18-5m
v=9-2.5m
plug (v=9-2.5m) in (3m+8v=55)
3m+8v=55
3m+8(9-2.5m)=55
3m+72-20=55
-17m=-17
m=1
plug (m=1) in (v=9-2.5m)
v=9-2.5m
v=9-2.5*1
v=6.5

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place
Step-by-step explanation:
I think you have forgotten to attach the question.
Anyways....
In order to find the area of a circle use the formula:
π[tex]r^{2}[/tex] Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π × [tex]3^{2}[/tex]
Since you have taken pi as 3.142...
3.142 × [tex]3^{2}[/tex]
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.
= 28.3 [tex]cm^{2}[/tex]

2 (3x - 5) + 4 = -18
Solve for 20 Points
Answer:
x = -2
Step-by-step explanation:
2(3x - 5) + 4 = -18
Distribute the 2
6x - 10 + 4 = -18
6x - 6 = -18
Add 6 to both sides
6x = -12
Divide both sides by 6
x = -2
Check:
2(3x - 5) + 4 = -18
substitute x = -2 into the original equation
2(3(-2) - 5) + 4 = -18
2(-6 - 5) + 4 = -18
2(-11) + 4 = -18
-22 + 4 = -18
-18 = -18
So x = -2 is true.
Answer:
x=-2
Step-by-step explanation:
2(3x-5)+4=-18
We move all terms to the left:
2(3x-5)+4-(-18)=0
We add all the numbers together, and all the variables
2(3x-5)+22=0
We multiply parentheses
6x-10+22=0
We add all the numbers together, and all the variables
6x+12=0
We move all terms containing x to the left, all other terms to the right
6x=-12
x=-12/6
x=-2

Answer:
28.27 ft²
Step-by-step explanation:
[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius
Plug in 3 for the radius
[tex]A=\pi (3)^2\\A=9\pi[/tex]
[tex]A=28.27[/tex] (approximate answer when rounded to the nearest hundredth)
Therefore, the area of the circle is 28.27 ft².
I hope this helps!
Answer:
exact area: 9 ft²
approximate area: 28.3 ft²
Step-by-step explanation:
An area cannot be in feet. It must be in a square unit such as square feet.
A = r²
A = ()(3 ft)²
A = 9 ft²
A = 9(3.14159) ft^2 = 28.3 ft²
Answer:
exact area: 9 ft²
approximate area: 28.3 ft²

SOS PLEASE HELP write the equation for this line
Answer:
y = - x + 3
or
x + y = 3
Step-by-step explanation:
Line is passing through the points (3, 0) & (0, 3)
y-intercept (b) = 3
Slope of the line (m) = (3 - 0)/(0 - 3) = 3/(-3) = - 1
Now, required equation of line is given as:
y = mx + b
y = - 1*x + 3
y = - x + 3
or
x + y = 3
