Answer:

3.3

Step-by-step explanation:

In equations you must remember the important rule of keeping both sides balanced. If you do one operation to one side you must do it to the other, for example if you added 1.1 to the right side you must do it to the left side in order to keep the equation balanced so,

→ 2.2 = z - 1.1

⇒ Add 1.1 to both sides to isolate z

→ 3.3 = z

⇄ We can substitute 3.3 back into the equation to see if we have the right solution, if we get 2.2 on both sides then our solution is correct

→ 2.2 = z - 1.1

⇒ Substitute 3.3 into the equation

→ 2.2 = 3.3 - 1.1

⇒ Simplify

→ 2.2 = 2.2

Our solution of z = 3.3 is correct

70 sixth-graders had an average weight of 90 pounds. 30 seventh graders had an average weight of 100 pounds. What was the averag

Brrunno [24]

We know that 70 sixth graders had an average weight of 90 pounds, and 30 seventh graders had an average weight of 100 pounds.

We know that the weight of all 70 sixth graders will be 70*90, since we're multiplying the total amount of students by the average.

Using this same logic tells us that the total weight for the 30 seventh graders is 30*100

The average weight for all 100 students will be the total weight of the sixth graders (which is 70*90) added with the total weight of the seventh graders (which is 30*100), then finally divided by the total amount of students in the sample space (which is 100).

$\dfrac{70(90)+30(100)}{100}$
