Step-by-step explanation:
1.)20x + 100 = 1440
-Let the number of couples be x. So, the total amount paid by all the couple’s are $20x. School paid $100 as security, so the total amount paid is
$ (20x + 100)
2.) 20x = 1440 - 100 ⇒ 20x = 1040
X = 52
3. ) The security money is $100, so the couples paid $1440- 100 = $1040 in total. As the couples paid $ 20 each than-
= 52
First you do 4 * 3y then 4 *5 and you get 12y + 20
Answer:
bx=-3
Step-by-step explanation:
-2(bx-5)=16
Use distributive property.
-2bx+10=16
Now, subtract 10 from both sides.
-2bx=6
Divide -2 from both sides.
bx=-3
Hope this helps!
