Changing the 30 to 10 is a 20 unit drop ( 30-10=20)
so the line would shift vertically down by 20
<span>The line will shift vertically down by $20.</span>
#1 is x+1
If x+3 is an even integer, say, for example, 4, then x would have to be an odd integer (x would have to be 1 in the example).
#2 is 5p
If the mangoes are still sold for 5 cents per mango, then the cost would still be 5p.
#3 is 20m, assuming Sam is running at the same rate every minute.
If Sam runs m miles per minute, how many miles will he run in 20 minutes?
A simple proportion can be formed:
m:1 = x:20
Multiply the left side by 20 to get: 20m:20 = x:20
Therefore, x is 20m.
Lets count...
3a...thats 1 term
3ab...thats 2
7b....thats 3
-2c....movin on up to 4
-4d....and we end at 5
so this expression has 5 terms since none of the terms can be combined :)
Answer:

Step-by-step explanation:
This expression was kind of trial and error for me seeing as I'm not really good at logic, but this is pretty basic. There are three possible places the parentheses can be placed (assuming each pair holds 2 terms);
The answer to the first expression would be 45, which is not equal to 11.
The answer to the second expression would be 15, which is also not equal to 11.
The answer to the last expression is 11, so that is the correct answer.
Hope this helped :D
