Answer:

{5}^{3}  \times  {5}^{x}  =  {5}^{7}  \\ 3 + x = 7 \\ x = 4

( {q}^{2} )^{y}  =  {q}^{6}  \\ 2y = 6 \\ y = 3

{1000}^{m}  \div  {100}^{n} =  {10}^{z}   \\  \frac{1000 ^{m} }{ {100}^{n} }  =  {10}^{z}  \\   \\ {10}^{m - n}  =  {10}^{z}

Can I have the brainliest please?

The answer ASAP I don’t understand this at all

Answer:

T = 530N + 250

Step-by-step explanation:

For the first plan, Heather will deposit $250 and then save $135 per month.

So, that is 250 + (135 x N) where N is the number of months she saves the $135.

So if it is for 3months,

We will have:

t¹ = 135N + 250

= 250 + (135 x 3)

= 250 + 405

= $655

For the second plan, there is no initial deposit, but she will save $395 per month.

That is 395 x N

t² = 395N

For 3months, we have 395 x 3 = $1185

Therefore the total for both plans in 3months = 655 + 1185 = $1840

Equation relating T to N

T = t¹ + t²

T = (135N + 250) + 395N

T = 135N + 250 + 395N

T = 530N + 250

What does the word distribute mean to you?
Nadusha1986 [10]

In mathematics, it means that you're giving another number something from another number.
