Again apply the distributive property
Or
take common 2 from the equation:
Answer:
B. 30
Step-by-step explanation:
First, you multiply by 5 from both sides of equation.
Simplify, to find the answer.
, which is our answer.

Answer:
- side lengths are not proportional
- 6, 8, 10
Step-by-step explanation:
1. The triangles are not similar because the ratios of side lengths are not the same:
3 : 4 : 5 ≠ 6 : 7 : 8
__
2. We can make the ratios be the same by multiplying the side lengths by a common value, such as 2:
3 : 4 : 5 = 6 : 8 : 10
If triangle B had side lengths of 6, 8, 10, then it would be similar to triangle A.
Answer:
1 < x < 4 . . . . {x | x < 4 <u>and</u> x > 1}
Step-by-step explanation:
We want to write the answer as a compound inequality, if possible. As it is written, we can solve each separately.
x + 1 < 5
x < 4 . . . . . . . subtract 1
__
x -4 > -3
x > 1 . . . . . . . add 4
So, the solution is ...
(x < 4) ∩ (x > 1) . . . . . . the intersection of the two solutions
As a compound inequality, this is written ...
1 < x < 4

Answer:
8 salt water
7 fresh water
Step-by-step explanation:
Let's represent salt water fish with the variable "s" and fresh water fish with the variable "f".
We can make a system of equations - one equation for the number of fish and the other for the price of the fish.
We know that the total number of fish Laura has is 15, and the total price of the fish was $23.
Solve the system of equations by subtracting the bottom equation from the top equation.
Laura bought 8 salt water fish. Since the total number of fish is 15, the number of fresh water fish must be 7.
