1. Kim and Alex have a total of $450.00. If Kim has 1/3 of the money how much money does Alex have ? 2. A pizza recipe required 2/3 cup of cheese per pizza. If Andrew wanted to make 3 pizzas .how many cups of cheese would he need.

3. convert 3kg 7g into grams

4. Keisha and Marielle have a total mass of 63 kg . if Keisha mass is 28 kg what fraction of the total mass does Marielle weight

1. 450/3 = 150. alex has two thirds, 150 x 2 = $300

2. 2/3 x 3 = 6/3 = 2 cups

3. 3kg = 3000g

4. 63 - 28 = 35. 35/63

answer:

n = 16

step-by-step explanation:

the equation for the area of a rectangle is a = lw.

"l" is length and "w" is width, "a" is the area.

we know the area is 24.

the length is n-3 and the width is 2.

substitute each of these values into the equation for area.

a = lw

24 = (n-3)(2)     < =expand this using distributive property to simplify

24 = 2n - 6

26 + 6 = 2n - 6 + 6   < =add 6 to both sides to isolate n

32 = 2n

32/2 = 2n/2   < =divide both sides by 2 to isolate n

16 = n

n = 16   < =standard formatting puts variable on left side
