Answer:
45
Explanation:
First we find the value of x, i.e.
2x – 1 = 9,
=> 2x = 9 + 1
=> 2x = 10
[tex] = > x = \frac{10}{2} [/tex]
=> x = 5
As we have got the value of x so now,
10x – 5
= (10 × 5) - 5
= 50 - 5
= 45 (Ans)
On a certain hot summer's day, 185 people people used the public swimming pool.The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $335.50.How many children and how many adults swam at the public pool that day?
Answer: 139 adults and 46 children. Did you not get this? I'm in 8th grade!!!!!!!
Explanation: a=adults, c=children
Rewrite equations:
a+c=185
2a+1.25c=335.5
Step: Solve a+c=185for a:
a+c=185
a+c+−c=185+−c (Add -c to both sides)
a=−c+185
Step: Substitute −c+185 for 'a' in 2a+1.25c=335.5:
2a+1.25c=335.5
2(−c+185)+1.25c=335.5
−0.75c+370=335.5 (Simplify both sides of the equation)
−0.75c+370+−370=335.5+−370 (Add -370 to both sides)
−0.75c=−34.5
−0.75c
−0.75
=
−34.5
−0.75
(Divide both sides by -0.75)
c=46
Step: Substitute 46 for 'c' in 'a' =−c+185:
a=−c+185
a=−46+185
a=139(Simplify both sides of the equation)
Answer:
a(adults)=139 and c(children)=46
The league mean batting average is 0.280 with a known standard deviation of 0.06. The Rattlers and the Vikings belong to the league.

Explanation:
These two right cylinders have the same height, 25 centimeters. The radius of the smaller cylinder is 5 centimeters and the radius of the larger cylinder is 3 times greater than that of the smaller cylinder. What is the ratio of the volume of the larger cylinder to the volume of the smaller cylinder? A. 6:1 B. 12:1 C. 9:1 D. 25:1
9514 1404 393
Answer:
C. 9:1
Explanation:
The volume is proportional to the square of the radius. When the ratio of radii is 3 : 1, the ratio of volumes is 3^2 : 1^2 = 9 : 1.
Answer:C! 9:1
