Step-by-step explanation:
you add the three p to p and that's 4p and
4p+7-5=-10
4p-2=-10
+2=+2
4p=-8
devide by four on both side so p is-2
56=2(pi)(r)
r=8.9127
pi(8.9127)^2=249.56cm^2
≈245cm^2 (3s.f.)
Answer: 2=x
Step-by-step explanation:
4x-1 + 2x-1 = 5x
First combine like terms together
4x-1 + 2x-1 is 4x+2x-1-1
4x+2x-1-1 =6x-2
4x-1 + 2x-1=6x-2
6x-2=5x
The oppisite of 6x is -6x so -6x on both sides of equation to keep it balanced
6x-6x-2=5x-6x
0-2=-1x
-2=-1x
Divide both sides of the equation by -1 since -1 is being multiplied by x and the oppisite of multiply is divide
-2/-1=-1x=-1
2=x
