Answer:
1. 6n - 15
2. x + 10
3. -4d + 15
4. true, associative property
5. distributive, commutative
Step-by-step explanation:
1. distribute 3/4 into the parentheses, so multiply 3/4 * 8 and 3/4 * -20
2. distribute the 2 into the parentheses so multiply 2 * 3x and 2 * 5, then combine like terms
3. distribute -3 into the parentheses so -3 * 4D and -3 * -5 then add like terms
4. add like terms on both sides of the equal sign and you get 10x on both sides. this is the associative property because it doesn't matter what's inside or outside the parentheses you get the same answer no matter how you add them up
5. the first part is distributive because you distributed the three into the parentheses and the second part is commutative because you switch them around and you can get the same answer
Answer:
the answer is x + 3
Step-by-step explanation:
Option A would run parallel because they have the same slope.
Answer:
m=5
Step-by-step explanation:
Let the number be represented by m.
Then twice the number m is represented as 2* m or 2m.
3 less than twice the number m = 2m -3
As per the question this value is 7.
Representing this in equation format:
=> 2m-3 = 7
=> 2m = 7+3 = 10
=> m= 10/2 = 5
Hence the number m is given by 5.
Verification:
Twice the number = 2* 5 = 10
3 less than twice the number m = 10 -3 = 7
This is the same as 7 as per the requirement.
