6 0

Answer:

There are no solutions.

Step-by-step explanation:

6-2(3-2x)=-4(3-x)

6 + -6 + 4x = -12 + 4x

4x = 4x - 12

-4 -4

0 = -12

Answer:

The radius of the oil spill growing at 2 feet per minute

Step-by-step explanation:

Area of a circle is

$A=\pi r^2$

Differentiating A with respect to r,

$\dfrac{dA}{dr} = 2\pi r$

When $A=100\pi$ ,

$100\pi = \pi r^2$

$r = 10$

The rate of growth of the spill is

$\dfrac{dA}{dt} = 40\pi$

This is equivalent to

$\dfrac{dA}{dt} = \dfrac{dA}{dr} \times \dfrac{dr}{dt}$

$\dfrac{dr}{dt} = \dfrac{dA}{dt}/\dfrac{dA}{dr} = \dfrac{40\pi}{2\pi r} = \dfrac{20}{r}$

$\dfrac{dr}{dt} = \dfrac{20}{10} = 2$

Carina spent a total of $5.27 buying a pineapple for $3.40 and some tomatoes that were on sale for $0.85 per pound. To determine

Neporo4naja [7]

Answer:

She subtracted 3.4 on the left and added 3.40 on the right

Step-by-step explanation:

3.40 + 0.85 x = 5.27

Subtract 3.40 from each side

3.40 -3.40+ 0.85 x = 5.27-3.40

.85x = 5.27 - 3.40

.85x =1.87

Divide by .85

.85x/.85 =1.87/.85

x = 2.2

6 cans of paint for a total of 90 dollars spent
I multiplied 120 by .20 to get 24 and subtracted it from 120 to get the amount that still has to be painted which is 96.
96 divided by 16 is 6 which is the number of cans of paint needed to paint the rest. Then just multiply by the cost (15$) and the answer is 90$
