Step-by-step explanation:

Let the new quantity be x.

x:1000=2:5

x/1000=2/5

(multiply both side by 1000)

1000 \times  \frac{x}{1000} = 1000 \times  \frac{2}{5}

x = 400

Aleksandr-060686 [28]

Answer:

  • 10 dimes and 4 quarters

Step-by-step explanation:

  • Number of dimes = d, each d = 10 c
  • Number of quarters = q, each q = 25 c
  • Total = $2 = 200 c

<u>Equations according the given:</u>

  • 10d + 25q = 200
  • d = q + 6

<u>Solve for q by substitution:</u>

  • 10(q + 6) + 25q = 200
  • 10q + 60 + 25q = 200
  • 35q = 140
  • q = 140/35
  • q = 4

<u>Find the value of d:</u>

  • d = 4 + 6 = 10

How do u find the slope of (6,-10), (-15,15)
Sergeu [11.5K]
m = \frac{y_{2} - y_{1}}{x_{2}-  x_{1}} = \frac{15 - (-10)}{-15 - 6} = \frac{15 + 10}{-21} = \frac{25}{-21} = -1\frac{4}{21}

     y - y₁ = m(x - x₁)
y - (-10) = -1⁴/₂₁(x - 6)
   y + 10 = -1⁴/₂₁(x) + 1⁴/₂₁(6)
   y + 10 = -1⁴/₂₁x + 7¹/₇
       - 10              - 10
           y = -1⁴/₂₁x - 3¹/₇

Question 10 of 15
AysviL [449]

Answer:

If Angelo can Mow his lawn in 2/3 of an hour or 40 minutes, it means that after 1/2 or 30 minutes 75% of the lawn will be mowed, this is because if he can mow the lawn in 40 and we want to know how much he can mow in 30 minutes this gives us the fraction 30/40 which is also equal to 3/4 or 75%. meaning that the correct picture is the one that shows that 3/4 of the lawn is mowed
