To complete the table, plug in the values into the equation (y=2x+3) if you already have the y then solve for x using inverse operations, and if you have the x then just use order of operations like normal

Given: 15+6(y−2)=21 Prove: y = 3 Drag and drop the reasons into the boxes to correctly complete the proof. Statement Reason 15+6
olchik [2.2K]

Answer:

Given:  15+6(y-2)=21

Distributive Property tells us that we multiply each term inside the parentheses with the term outside of the parentheses.

a\cdot(b-c) =a\cdot b -a\cdot c

Using distributive property on expression 6(y-2) to solve the further expression as:

15+6\cdot y - 6\cdot 2=21

Simplify:

15+6y-12 =21

Subtract the number 12 from 15 we get 3;

therefore, the expression become:

6y+3=21

Subtraction property of equality tells us that subtract the same number from both sides of an equation.

Now, subtract 3 from both the sides we get;

6y+3-3=21-3

Simplify:

6y=18

Now, divide by 6 on both the sides we get;

\frac{6y}{6}= \frac{18}{6}

On simplify we get;

y =3           Hence Proved!

What is 70% of 40,000.
timurjin [86]

Answer:

x = 28,000

Step-by-step explanation:

"What" is our unknown, x; "is" is an equals sign; 70% expressed as a decimal is .70; "of" means to muliply.

Our equation, then, is

x = .70(40,000) so

x = 28,000

WILL MARK AS BRAINLIEST PLZ HELP
nignag [31]
The formula is
I=prt
I interest earned 14.65
P initial deposit ?
R interest rate 0.025
T time 2 years
Plug in the formula
14.65=p×0.025×2
Solve for p
14.65=0.05p
Divide both sides by 0.05
P=14.65/0.05
P=293....answer

Hope it helps!

What is the value of the sum of all the terms of the geometric series 300, 60, 12, …?
ruslelena [56]
<h3>Answer:   375</h3>

=========================================

Work Shown:

a = 300 = first term

r = 60/300 = 0.2 = common ratio

We multiply each term by 0.2, aka 1/5, to get the next term.

Since -1 < r < 1 is true, we can use the infinite geometric sum formula below

S = a/(1-r)

S = 300/(1-0.2)

S = 300/0.8

S = 375

----------

As a sort of "check", we can add up partial sums like so

  • 300+60 = 360
  • 300+60+12 = 360+12 = 372
  • 300+60+12+2.4 = 372+2.4 = 374.4
  • 300+60+12+2.4+0.48 = 374.4+0.48 = 374.88

and so on. The idea is that each time we add on a new term, we should be getting closer and closer to 375. I put "check" in quotation marks because it's probably not the rigorous of checks possible. But it may give a good idea of what's going on.

----------

Side note: If the common ratio r was either r < -1 or r > 1, then the terms we add on would get larger and larger. This would mean we don't approach a single finite value with the infinite sum.
