Answer:

$1.20

Step-by-step explanation:

Ratio:

Grams : Kilograms

1 : .001

Multiply both sides by 20 to convert grams to kilograms:

Grams : Kilograms

1 : .001

x20 x20

20 : .02

This means that 20 grams of lead = .02 kilograms of lead

Price:

Cost : Kilogram

$60 : 1

Multiply both sides by .02 to find the price of the lead:

Cost : Kilogram

$60 : 1

x.02 x.02

$1.20 : .02

Therefore, .02 kg of lead costs $1.20.

Given that JKLM is a parallelogram, solve for x.

Olegator [25]

Answer:

x = 4

Step-by-step explanation:

In a parallelogram, the opposite sides are equal/congruent. This means that KL and JM are equivalent.

In other words, $7x - 2 = 12x - 22$ , and we have to solve for x.

Step 1: Subtract 12x from both sides.

$7x-2-12x=12x-22-12x$
$-5x-2=-22$

Step 2: Add 2 to both sides.

$-5x-2+2=-22+2$
$-5x=-20$

Step 3: Divide both sides by -5.

$-5x/-5 = -20/-5$
$x = 4$

Therefore, x = 4.
