Answer:

x ≤ 2

Step-by-step explanation:

Isolate the variable, x. Note the ≤ sign, treat it like an equal sign, what you do to one side, you do to the other.

First, subtract 3 and x from both sides:

2x (-x) + 3 (-3) ≤ x (-x) + 5 (-3)

2x - x ≤ 5 - 3

Simplify:

2x - x ≤ 5 - 3

x ≤ 2

x ≤ 2 is your answer.

Part of the proceeds from a garage sale was $470 worth of $10 and $20 bills. If there were 14 more $10 bills than $20 bills, fin

Brums [2.3K]

There are 25 $10 bills and 11 $20 bills.

Step-by-step explanation:

Given,

Worth of proceeds from garage = $470

Let,

x be the number of $10 bills

y be the number of $20 bills.

According to given situation;

10x+20y=470 Eqn 1

x = y+14 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$10(y+14)+20y=470\\10y+140+20y=470\\30y=470-140\\30y=330$

Dividing both sides by 30

$\frac{30y}{30}=\frac{330}{30}\\y=11$

Putting y=11 in Eqn 2

$x=11+14\\x=25$

There are 25 $10 bills and 11 $20 bills.
