Mark and his workout partner are lifting weights together, doing many sets of each exercise. On a certain exercise, Mark is using a 40-pound bar, increasing the amount of weight he lifts by 5 pounds on each set. His partner, meanwhile, started out using a 20-pound bar and is upping the weight by adding 10 pounds on every set. Eventually, Mark and his workout partner will be lifting the same amount, and will take turns using the same barbell. How much weight will they be lifting then?

x = 23.78

step-by-step explanation:

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.

i think its 7.6

if so your welcome
