Answer:
if we take the number of quarters Barrett have to be x we know Penelope has twice that ie 2x. so in total they have 2x+x = 60, 3x = 60; so x= 60/3 = 20.
Barrett has 20 quarters.
The rewritten form of the given expression using the fewest terms is; 3x + 6.
<h3>What is the rewritten form of.the expression using the least possible terms?</h3>
It follows from the task content that the given expression is to be rewritten using the fewest terms.
Since the given expression is;
( −2x − 13 ) + ( 19 + 5x )
By getting rid of the parentheses; we have;
-2x - 13 + 19 + 5x
By collecting like terms; we have;
-2x + 5x - 13 + 19
3x + 6
Therefore, the required rewritten form of the given expression is; 3x + 6.

Answer:


Step-by-step explanation:
In the triangle we have the following trigonometric equations:

and also:

C. 10r-3
Because 2r+5=7, the minus 6 and 7 which gives you 1 then minus 4 and 1 witch is 3 then you do 10r-3 and it will get you to 2r+5=7 again. I hope this helped!
