Answer:
The number is -1/2
Step-by-step explanation:
Let x be the number
2x+8 = 7
Subtract 8 from each side
2x+8-8 = 7-8
2x = -1
Divide each side by 2
2x/2 =-1/2
x = -1/2
The number is -1/2
Answer:
(1,0) would be the correct answer.
Step-by-step explanation:
any point that is reflected across y=x will change unless it is on the line. if reflected across y=x, the coordinates will become y,x

Step-by-step explanation:
When the numerator is less than the denominator, the result is always less than 1, that is 0. something and this will give a percentage less than 100, but when the numerator is greater than the denominator, th result is greater than 1, and any figure greater than 1 gives a percentage that is greater than 100
example
Numerator >Denominator
=4/2*100
=2*100
=200%
Numerator <Denominator
=2/4*100
=0/5*100
=50%
Answer:
900π m2
Step-by-step explanation:
surface are of a sphere is 4π(r)^2
now diameter is 30m,so radius will be 15 m
how, 4π(15)^2=900π (m2)
