Step-by-step explanation:
consecutive numbers follow each other thus if the first is x the second will be x+1 e.t.c:
1. x+x+1+x+2+x+3=2
x+x+x+x+1+2+3=2
4x=2-6
4x= -4
x= -1
The numbers are -1, 0, 1 and 2
2.x+x+1+x+2= -6
3x+3=-6
3x= -6-3
3x= -9
x=-3
The numbers are -3,-2 and -1
71 degrees you add 82+27= 109 then 180-109=71
Answer: B. 254.34 cm^2
Step-by-step explanation:
The area of a circle is pi times the radius squared.
Using the diameter we have to find the radius.
The diameter is two times the radius meaning that the radius is half the diameter.
18/ 2 = 9
The radius will be 9 cm
Now using the formula v= pi * r^2 , input the value for pie and the radius and solve for v the volume
v = 3.14 * 9^2
v= 3.14 * 81
v = 254.34 cm^2
It can be achieved by substituting the formula for length i.e x(A) = A/6 into the formula for Volume.
in the diagram( please mind my writing)
the x(A) is substituted into V(x) .
Only thing left is substitution of the values .
hope this helps .
Answer:
y = 8
Step-by-step explanation:
2y + 3 = 19
2y = 19 - 3
2y = 16
y = 16/2
y = 8
Hopefully this help u
