Answer:
the answer has to be 3(17-y)
Step-by-step explanation:
I'm pretty sure about that cause what I did at first is subtract the numbers.
<em>6</em><em>0</em><em>-3y-9</em>
=51-3y
factor our 3 from the expression.
3(17-y)
Answer:
Noah's claim is correct
Step-by-step explanation:
B O D M A S - Brackets, Over, Division, Multiplication, Addition and Subtraction, this means that you must do the addition first.
2x+ 4x = 6x
9x - 6x = 3x
Noah is correct as the - sign tells us that you have to subtract everything after the 9x
Hope this is ok and helps a little bit
Answers:
24 quarters
22 nickels
==========================================================
Work Shown:
q = number of quarters
n = number of nickels
q+n = 46 coins total which solves to n = 46-q
25q = value of all the quarters in cents
5n = value of all the nickels in cents
25q+5n = value (cents) of all the coins of both types
25q+5n = 710 cents total = $7.10
-------------
Apply substitution.
25q+5n = 710
25q+5(46-q) = 710
25q+230-5q = 710
20q+230 = 710
20q = 710-230
20q = 480
q = 480/20
q = 24
They have 24 quarters
This yields 25*q = 25*24 = 600 cents = $6.00 so far.
Use that value of q to find n
n = 46-q
n = 46-24
n = 22
They also have 22 nickels.
They have an additional 5n = 5*22 = 110 cents = $1.10
In total, they have 6.00+1.10 = 7.10 dollars which confirms we have the correct coin counts. Also, q+n = 24+22 = 46.
