A bag contains purple marbles and green marbles, 55 in total. The number of purple marbles is 7 more than 2 times the number of
kirill [66]

There are 39 purple marbles in the bag

Step-by-step explanation:

The given is:

  • There are 55 purple and green marbles in total in a bage
  • The number of purple marbles is 7 more than 2 times the number of green marbles

We need to find how many purple marbles in the bag

Assume that the number of the purple marbles is P and the number

of the green marbles is G

∵ There are P purple marbles and G green marbles in the bag

∵ There are 55 marbles in the bag

∴ P + G = 55 ⇒ (1)

∵ The number of purple marbles is 7 more than 2 times the number

   of green marbles

- Add 7 and 2 times G to get P

∴ P = 7 + 2 G

- Subtract 2 G from both sides

∴ P - 2 G = 7 ⇒ (2)

Let us solve the system of equations to find P

Multiply equation (1) by 2 to eliminate G

∵ 2 P + 2 G = 110 ⇒ (3)

- Add equations (2) and (3)

∴ 3 P = 117

- Divide both sides by 3

∴ P = 39

∵ P represents the number of the purple marbles in the bag

∴ There are 39 purple marbles in the bag

There are 39 purple marbles in the bag

The width of a rectangle is 7 meters greater than its length. If the area of the rectangle is 170 square meters, write the quadr
soldier1979 [14.2K]
Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170

And that is the answer.

The number of new visits to a website is decreasing exponentially. It can be modeled by the function h(d)=2170(0.92)^d, where h
In-s [12.5K]

Answer:

2) -141 hits/da  

Step-by-step explanation:

Calculate the values of h(2) and h(4)

h(2) = 2170(0.92)² = 2170 × 0.8464 = 1837

h(4) = 2170(0.92)⁴ = 2170 × 0.7164 = 1555

Calculate the average rate of change

Rate of change = (y₂ - y₁)/(x₂-x₁) = (1555 -1837)/(4 - 2) = -282/2 = -141 hits/da

The average rate of change is -141 hits/da.

In the figure below, the red curve represents the function h(d), while the green dashed line represents the average rate of change over the interval 2 ≤ d ≤4.
