Answer:
Step-by-step explanation:
3x + 2 + 58 = 90
3x + 60 = 90
3x = 30
x = 10
it's adjacent
9 dollars represents 90% of the cost. Divide 9 by 0.90 to get the original price, 10 dollars
Answer:
Simplifying
6n + 7 + -2n + -14 = 5n + 1
Reorder the terms:
7 + -14 + 6n + -2n = 5n + 1
Combine like terms: 7 + -14 = -7
-7 + 6n + -2n = 5n + 1
Combine like terms: 6n + -2n = 4n
-7 + 4n = 5n + 1
Reorder the terms:
-7 + 4n = 1 + 5n
Solving
-7 + 4n = 1 + 5n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-5n' to each side of the equation.
-7 + 4n + -5n = 1 + 5n + -5n
Combine like terms: 4n + -5n = -1n
-7 + -1n = 1 + 5n + -5n
Combine like terms: 5n + -5n = 0
-7 + -1n = 1 + 0
-7 + -1n = 1
Add '7' to each side of the equation.
-7 + 7 + -1n = 1 + 7
Combine like terms: -7 + 7 = 0
0 + -1n = 1 + 7
-1n = 1 + 7
Combine like terms: 1 + 7 = 8
-1n = 8
Divide each side by '-1'.
n = -8
Simplifying
n = -8

Answer:
The common difference is -20
Step-by-step explanation:
Simply subtract 5 from -15
-15-5 = -20
Answer: 1/4
Step-by-step explanation:
To determine the probability of landing on blue, you divide by the total number of spins.
In this experiment, the probability of the spinner landing on blue after 20 spins would be 15%.
This makes the probability of landing on blue to be:
Pr (landing on blue) / Pr (total trials) = 5/20
This gives 1/4
