10.5*5= 52.5 is the correct answer to the question
First you distribute. 4 to x-1 and 3 times 2x-5 you should get 4x-4-6x+15 because -3 times -5 is positive 15. Combine like terms 6x-4x is 2x and 15-4 is 11
Answer:
Step-by-step explanation:
You have to use the triangle inequality theorem:
12cm, 4cm, xcm
x > 4cm - 12cm
x > -8cm
x < 12cm - 4cm
x < 8cm
-8cm < x < 8cm
Answer:
y = x+1
Step-by-step explanation
The equation in slope intercept form is expressed as y = MX+c
m a the slope
Get the slope of the line
Given the line x-y =9
-y = -x+9
y = x-9
Slope of the line is 1
Since it is parallel to the given line, the slope o the required line is also 1
Substitute m = 1 adnd (4,5) into the point slope form
y-y0 =m(x-x0)
y - 5 = 1(x-4)
y-5 = x-4
y= x-4+5
y = x+1
Hence the required equation is y = x+1
Answer:
Radius: 19 yards
Diameter: 38 yards
Circumference: 119. 32
Step-by-step explanation:
Radius
To find the radius you divide the diameter by 2 because, the diameter is a; a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
So 38 ÷ 2 = 19
So the radius is 19.
_____________________
Circumference
To find the Circumference you need to do 2·π·19
C=2·π
2·π = 6.28
6.28 · 19 = 119. 32
Circumference is 119. 32
