You have to do whatever is in the parentheses first which gets you:
4-(-2)
Two negatives equal one positive so it would be:
4+2
And 4 plus 2 is of course 6.
The expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.
Solution:
Given expressions are 15t – 2t and 2t – 15t.
To determine 15t – 2t is equivalent to 2t – 15t or not.
Substitute t = 2 in above two expressions.
15t – 2t = 15(2) – 2(2)
= 30 – 4
= 26
2t – 15t = 2(2) – 15(2)
= 4 – 30
= –26
The values of the expressions are different when t = 2.
So, 15t – 2t is not equivalent to 2t – 15t.
Hence the expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.
Answer:
x -2 = 3x +2
Step-by-step explanation:
For the purpose, we use math symbols to express the relation described by the English.
<h3>Translation</h3>
When x represents "a number," we have ...
- two less than a number: x -2
- the product of 3 and the number: 3x
- 2 more than the product: 3x +2
- is the same as: =
Then the English description can be translated to ...
x -2 = 3x +2
__
<em>Additional comment</em>
Adding -2-x to both sides gives ...
-4 = 2x
-2 = x . . . . . divide by 2
The number is -2.
Answer:
x = 2 1/3
y = 14 / (2 1/3) = 14 / (7/3) = 14*3/7 = 42/7 = 6
y = 6
x = 4 1/5
y = 14 / (4 1/5) = 14 / (21/5) = 14*5/21 = 70/21 = 3 7/21 = 3 1/3
y = 3 1/3
x = 7/6
y = 14 / (7/6) = 14*6 / 7 = 12
y = 12
