A cafeteria starts with 750 fish sticks for lunch. Each meal they serve uses 6 of the fish sticks. At the end of the lunch there are 42 fish sticks left. Let n be the number of meals served in the cafeteria. Set up and solve an equation to find the value of n.
I will give brainliest and i put 13 points into this

Answers

Answer:

The value of N = 118

Step-by-step explanation:

750 = 6n + 42

move all the numbers that don't contain n to the right side

6n = 750 - 42

6n = 708

708 / 6 = 118

n = 118

plug the numbers back in

6 ( 118) = 708

708 = 708

plug the 42 back in

708 + 42 = 750

Answer:  Yellow flowers 3 1/3 And red flowers 7

Step-by-step explanation:

So you take 3 and put into 1/3. You get 3 1/3 because if you multiply them together you get 21 and there's 21 yellow flowers in  total. Then for "R" (red flowers) you would divide 21 by 3 (the reason you divided it by 3 is because there's 3 times the number of red flowers.) you would get 7.

Yellow Flowers: 3 1/3

Red Flowers: 7

yellow flowers are 3 and a half and red flowers is 7 ;)

Answer:

130356 grams.

Step-by-step explanation:

The table shown in the picture is a proportion table. What I did here was divide 34932 by 4.1. That gave me 8520. So, 1 cm³ of metal is 8520 grams. Now multiply that by 15.3.

8520/1 * 153/10

Cross-cancellation (8520 becomes 852, 10 becomes 1 (GCF: 10))

852 * 153

Multiply 852 by 153 to get 130356.

130356

15.3 cm³ of metal weighs 130,356 grams.
