Answer:
Third turn point = 21 points
Step-by-step explanation:
Given:
First turn point = 12
Second turn point = 15
Find;
Third turn point
Computation:
First turn point = 12
Assume;
Point for outer circle = a
Point for inner circle = b
So,
3a = 12
Point for outer circle = 4 point
Second turn point = 15
So,
2a + b = 15
2(4) + b = 15
Point for inner circle = 7
Third turn point = 3 x 7
Third turn point = 21 points
Answer:
, solution is $14.29
Step-by-step explanation:
We can create an equation for this scenario to try and solve it.
Assuming the cost of the CD is x, it’s sale tax will be 0.05x (as that is 5% of x, 0.05.)
We can write the equation in two ways:
or .
Assuming we take the second one (easier to work with), we can divide both sides by 1.05. The equation simplifies to x = 14.289... which rounds to x = 14.29.
Therefore, the equation is and the solution is $14.29.
Hope this helped!

Step-by-step explanation:
The expression -1 × 2 × -3 × 4 × -5 has a negative value ⇒ C
Step-by-step explanation:
Let us revise the products of negative and positive
- (+) × (+) = (+)
- (-) × (-) = (+)
- (-) × (+) = (-)
- (+) × (-) = (-)
- The product of three (-) is (-) ⇒ -2 × -3 × -1 = -6 (-2 × -3 = 6 × -1 = -6)
- The product of four (-) is (+) ⇒ -2 × -3 × -1 × -4 = 24 (-2 × -3 = 6 × -1 = -6 × -4 = 24)
- If there are even negative signs, then the product will be positive
- If there are odd negative signs, then the product will be negative
A. -1 × -2
∵ There are two negative signs
∵ 2 is an even number
∴ -1 × -2 has a positive value
B. 1 × -2 × -3 × -4 × -5
∵ There are four negative signs (-2 , -3 , -4 , -5)
∵ 4 is an even number
∴ 1 × -2 × -3 × -4 × -5 has a positive value
C. -1 × 2 × -3 × 4 × -5
∵ There are three negative signs (-1 , -3 , -5)
∵ 3 is an odd number
∴ -1 × 2 × -3 × 4 × -5 has a negative value
D. 1 × -2 × 3 × -4 × 5
∵ There are two negative signs (-2 , -4)
∵ 2 is an even number
∴ 1 × -2 × 3 × -4 × 5 has a positive value
The expression -1 × 2 × -3 × 4 × -5 has a negative value
