Step-by-step explanation:
first let's write out the problem
0.99 is what percent of 9.90 = 0.99=9.90*x
We need to what c is so we would do the opposite operation of multiplication, division so we get,
0.99/9.90= .1

Answer:
x²+x-30
x=5
Step-by-step explanation:
The equation is
(x+3+x-1)/2 × x=30
x²+x-30 (it's the quadratic equation)
x²+6x-5x-30=0
x(x+6)-5(x+6)=0
(x+6)(x-5)=0
x=-6
x=5
It's impossible for Length to be negative
So x=5
Answer:
C, 2x + 22
Step-by-step explanation:
Its just simple combining like terms
3x-x=2x, 10+12=22
15= 3*5
14= 2*7
LCM(15,14)= 2*3*5*7= 210
15 and 14 go into 210 evenly~
