Answer:

Step-by-step explanation:

Ok, so remember your order of operations here.

Also, Remember that what we do to one side, we must do to the other side.

We cant solve whats in the parentheses, so that wont come first. The next best thing is the multipication of 0.8 in front of it:

0.8x(2x-4)

=

1.6x-3.2

Now lets rewrite the equation as:

1.6x-3.2=16

Now lets simply solve the rest:

1.6x=19.2

All I did is add 3.2 to both sides so I could get 1.6x on its own.

What is left is just dividing 1.6x to get 1x:

1.6x/1.6=19.2/1.6

This gets us:

x=12

This is because we divided 1.6 from both sides so that 1.6x became just x.

Answer:

<u>12</u>

Hope this helps!

F(2) = 20 and f(3) = 12
Illusion [34]

Answer: 10(2)=20 and 4(3)=12

Step-by-step explanation:

1) Divide 20 by 2 which would be 10 that gives you the sum of F

2) Divide 12 by 3 which is equals 4 so thats the sum of F for f(3)=12

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the
vitfil [10]

Let's solve for d.

fd=(7)(1.06)d

Step 1: Add -7.42d to both sides.

df+−7.42d=7.42d+−7.42d

df−7.42d=0

Step 2: Factor out variable d.

d(f−7.42)=0

Step 3: Divide both sides by f-7.42.

d(f−7.42)f−7.42=0f−7.42

d=0f−7.42

Answer:

d=0f−7.42

Any possible way i can get some help? steps or not.. i’m in need..
igor_vitrenko [27]

Answer:

The answer to your question is:

7.-  y = 6 units

8.-  a = 10.6 in

9.- 41.6 ft

Step-by-step explanation:

7.- That is a right triangle and the hypotenuse is y.

     Use the pythagorean theorem to find y.

        y² = (3√2)² + (3√2)²

         y² = 9(2) + 9(2)

         y² = 18 +18

         y² = 36

        y = 6 units

8.-

  hypotenuse = 15 in

  c² = a² + b²

  a = b  so

 c² = a² + a²

c² = 2a²

c² / 2  = a²

a² = 15² / 2

a² = 112.5

a = 10.6 in

9.-

Use trygonometry to solve this triangle

height = 36 feet

sin Ф = 36 / hypotenuse

hypotenuse = 36 / sin Ф

hypotenuse = 36 / sin60

hypotenuse = 36 / 0.86

hypotenuse = 41.6 ft

Sharon bought some bottles of water at Randolph's Grocery. Use the graph shown to answer the question
alexandr1967 [171]

Answer:

A. Sharon spent $10 to buy 25 water bottles at Randolph's Grocery

Step-by-step explanation:

I know this because for 10 bottles it's $4.00 so you would do that twice which would be $8 and then for 5 bottles it's $2.00.

So all together that would be 25 bottles and the total cost would be the $10
