9 + 13x = 6 + 19x since x is same variable (year)
9 - 6x = 6
-6x = -3
x = 1/2 yr or 6 months
I believe it would take 10 cups. The reason being 4 cups of 1/4 equals 1 so double it to 8 and add 2 more cups to make 2/4. So add 8 plus 2 and get 10.
Answer: 4r = 4
Step-by-step explanation:
Ruth bought 4 rulers and each ruler is to be represented by r. She therefore bought:
= 4r
She bought these for a total of $4.00 so the equation then becomes:
4r = 4.00
Equation representing situation is: 4r = 4
1) we calculate the total cost of all items:
Total cost=27 * $1.25 + 5 *1.99$ + 1*1.5$=$33.75 + $9.95 + $1.5=$45.2
2)we express the total cost in cents:
$1=100 cents
$45.2=$45.2 * (100 cents /$1)=4520 cents.
3)we divide 4520 cents among the number of pupils
Each student will pay=4520 cents / 26 =173.84... cents≈174 cents.
Answer: Each student will pay 174 cents.
It is a divisor
hope this helps
