Answer:

y = 8

Step-by-step explanation:

Ok, so first you want to try to get y by itself. So you would subtract 6 from both sides.

3y + 6 = 30

       -6   -6

3y = 24

Now, you want to divide 3 from both sides. Doing this will get the y by itself.

3y = 24

----   ----

3       3

y =  8

I need help on this problem, mostly understanding though, please help me
mars1129 [50]

well, let's notice something, a cube, all equal sides, has a side of 6, thus its volume is simply 6*6*6 = 216 cm³.

now, a rectangular prism, is a cuboid as well, but with varying dimensions.

let's notice something 6*6*6 is simply a multiplication of 3 numbers, let's then do a quick <u>prime factoring</u> of those numbers, well, 6 factors only into 2 and 3, so then the product of 6*6*6 can really be rewritten as (2*3)(2*3)(2*3).

well, regardless on how we rearrange the factors, the product will be the same, commutative property, so the rectangular prism will more or less have the same product and thus just about the same prime factors.

so let's rearrange on say hmmm height = 3 cm, length = 3*3 cm and width = 2*2*2 cm, notice, is still the same prime factors, 3*9*8 = 216 cm³.

Check the picture below.

Answer:

3. B.

1. 3551.

Step-by-step explanation:

3. For two equations to have infinite solutions, the equations must be the same.

y = -5x + 6

5x + y - 6 = 0

Multiply the whole thing by 2.

10x + 2y - 12 = 0

B.

1. Michelle rides roller coasters 3 times and plays the super swing 5 times, which means that A = 3 and B = 5.

Marty rides the roller coasters 5 times and plays the super swing 1 time. That means C = 5 and D = 1.

So, your answer will be 3551.

Hope this helps!
