Answer:

2 marbles

Step-by-step explanation:

Lana has 3 bags with x marbles in each bag totaling 12 marbles

3x=12

Divide by 3

3x/3 =12/3

x =4

Each bag has 4 marbles

Markus has 3 bags with y marbles totaling 18 marbles

3y =18

Divide each side by 3

3y/3 =18/3

y =6

Each bag has 6 marbles

6-4 =2

There are 2 more marbles in Markus' bags than in Lara's

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.
natta225 [31]

we have

2x-2y=6 ------> equation 1

4x+4y=28 ------> equation 2

Multiply by 2 the equation 1

4x-4y=12 ------> equation 3

Sum equation 2 and equation 3

4x+4y=28\\ 4x-4y=12\\ ------\\ 8x=40\\ x=40/8\\ x=5

Substitute the value of x in the equation 2

4x+4y=28

4*5+4y=28\\ 4y=28-20\\ 4y=8\\ y=8/4\\y=2

therefore

the answer is the option B

On average, a gym claims that 85% of its members renew their memberships every year. If the gym has 400 members, predict how man
lana [24]

Answer:

340 people would renew their membership if the gym had 400 members

The gym's claim is not accurate, because the prediction should be 340 people instead of 330

Step-by-step explanation:

With 400 members, we can predict how many will renew their membership by multiplying 400 by 0.85:

400(0.85)

= 340

So, this would predict that 340 people would renew their membership.

The gym's claim that 330 members would renew their memberships is not accurate, because the correct prediction should be 340 people.

REY [17]
It is a pattern so 2*3=6
3 times 4 is 12
4 times 5 is 20 
5 times 6 is 30
6 times 7 is 42
so, 9 times 8 is 72.
