Answer:
Pretty sure the answer would be x=6
Step-by-step explanation:
The number (x) in: "3 more than twice a number is 15" is what we are solving here.
In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 3, you get 15.
To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 15
Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 3 = 15
2x + 3 - 3 = 15 - 3
2x = 12
2x/2 = 12/2
x = 6
Answer:
Step-by-step explanation:
Given that,
Speed of a toy car, v = 7.2 m/s
Radius of the circular track, v = 1.5 m
We need to find the acceleration of the car. When an object moves in a circular path, it will have centripetal acceleration. It can be given as follows :
So, the centripetal acceleration of the toy car is 
. Hence, the correct option is (c).

im going to assume the 3x2 mean 3 times 2
Answer:
12
Step-by-step explanation:
21x + 4x = 300 Put brackets around the first two terms.
(21x + 4x) = 300 Pull the x outside the brackets. Use the distributive property. Combine the left
25x = 300 Divide by 25
25x/25=300/25 Do the division
x = 12
Answer: 6
Step-by-step explanation: divide 18 by 6, then subtract 2 from the answer. Multiply by 6.
18/6=3-2=1*6=6
