Answer:
9n-3
Step-by-step explanation:
since 9n has a variable, u can't add or subtract 9n with 3
but if you were multiplying: 9n(3) then it would be 27n

Answer:
B. All real numbers
Step-by-step explanation:
2(x + 1) = 2x + 2
Distribute the 2 inside the parenthesis.
2x + 2 = 2x + 2
Since the two expressions are equal and will stay equal with any value, the answer to this question is All real numbers.
Example:
2(x + 1) = 2x + 2
2(5 + 1) = 2(5) + 2
2(6) = 10 + 2
12 = 12
2(x + 1) = 2x + 2
2(150 + 1) = 2(150) + 2
2(151) = 300 + 2
302 = 302
The expression is equal for any value put in x.
To answer the question above, isolate F on the other side of the equation by multiplying both sides by 9/5. This gives,
(9/5) C = F - 32
Next, transpose -32 to left side.
(9/5)C + 32 = F
Rearrange the equation to give an answer of
F = (9/5)C + 32
Answer:
Step-by-step explanation:
Use the slope formula.
<h3 /><h3>What is a slope?</h3>
Slope is a surface with one end higher than the other and with no steps. It proceeds at an angle. The path sloped down to the beach.
So, the property possessed by a line or surface that departs from the horizontal.
<u>Slope formula:</u>
(-6,-2) (4,1)
<u>Rewrite the problem down.</u>

<u>Solve.</u>
1-(-2)=1+2
<u>Add.</u>
1+2=3
4-(-6)=4+6
4+6=10

Therefore, the slope is 3/10, which is our answer.

Answer:
$30
Step-by-step explanation:
If $25 is 100%,
$2.5 is 10%
$0.25 is 1%
$3.75 is 15%
$0.75 is 3%
Then add $25, $3.75 and 0.75 which is also equivalent to 100%+15%+3%=29.5 and if you rounded it up to the nearest cent it is 30
