Answer:

  • 100 and 600

Step-by-step explanation:

Let the numbers be a and b.

<u>We have:</u>

  • a + b = 1600

and

  • 0.12a = 0.2b, simplified as b = 0.6a

<u>Substitute b into the first equation:</u>

  • a + 0.6a = 1600
  • 1.6a = 1600
  • a = 1600/1.6
  • a = 1000

<u>Find b:</u>

  • b = 0.6*1000 = 600

there is an equation for straight lines which goes

y-y,=m(x-x,)

where( x, , y, ) is any coordinate on the line and m is the gradient

so your answer is

does this make sense?

Brandon is shopping at Old Navy during a sale. All shorts are $16 each and all t-shirts are $10 each.He has $100 to spend and wo
DaniilM [7]
Let
x = the number of shorts bought
y =  the number of t-shirts bought

A pair of shorts costs $16 and a t-shirt costs $10. Brandom has $100 to spend.
Therefore
16x + 10y ≤ 100
This may be written as
y ≤ - 1.6x + 10                 (1)

Brandon wants at least 2 pairs of shorts. Therefore
x ≥ 2                               (2)

Graph the equations y = -1.6x + 10 and  x = 2.
The shaded region satisfies both inequalities.

Answer:
Two possible solutions are
(a) 3 pairs of shorts and 4 t-shirts,
(b) 4 pairs of shorts and 2 t-shirts.

Michele is starting a new pool-cleaning business. It costs her $85 to purchase supplies. Michele charges $40 each time she clean
Alex787 [66]

Answer:

Option A : y = 40x - 85 is the correct answer.

Step-by-step explanation:

Given that:

Cost of purchasing supplies = $85

Cost charged for cleaning a pool = $40

Let,

x be the number of pools cleaned.

y be the profit

Profit = Cost of pools cleaned - purchase price of supplies

y = 40x - 85

Hence,

Option A : y = 40x - 85 is the correct answer.
