Answer:
10 visits tops
Step-by-step explanation:
50- 19.95= 30.05
30.05/2.75= 10.9 which means 10 times.
500/1000 = 1/2 Same distance to zero and one
If the length of the entire screwdriver is 19cm, and the handle is 5cm, subtract the length of the handle from the total length to find the length of the top of the screwdriver.
19 - 5 = 14
The top of the screwdriver is 14cm long.
Answer:
The value of r=
The value of x=
Step-by-step explanation:
Given that,
A) 
Now,

8(2r-2)=9(7r+10)
16r-16=63r+90
-16-90=63r-16r
-(16+90)=47r
-106=47r
r=
B) 
Now,

5(x+5)=9[3(x-2)-1]
5x+25=9[3x-6-1]
5x+25=9[3x-7]
5x+25=27x-63
25+63=27x+5x
83=32x
x=
