3(2x + 9) = 4 + 3x - 1

6x + 27 = 3 + 3x

6x - 3x = 3 - 27

3x = -24

x = -8

Answer:

x = -8

Step-by-step explanation:

3(2x+9) = 4+3x-1

Distribute

6x+27 = 4+3x-1

Combine like terms

6x+27 = 3+3x

Subtract 3x from each side

6x+27-3x = 3+3x-3x

3x+27 = 3

Subtract 27 from each side

3x+27-27 = 3-27

3x = -24

Divide by 3

3x/3 = -24/3

x = -8

Monica deposits $400 into a savings account that pays a simple interest rate of 4.4%. Paul deposits $500 into a savings accou

DIA [1.3K]

Answer:

From the above calculation it is clear that The interest earn by Monica is less than the The interest earn by Paul , so Monica is wrong

Step-by-step explanation:

Given as :

The principal amount deposited by Monica in account = $ 400

The rate of interest = 4.4 % at simple interest

The time period = 1 years

Let The interest earn by Monica = $ x

<u>From simple interest </u>

Simple Interest = $\dfrac{\textrm principal\times \textrm rate\times \textrm time}{100}$

Or, $ x = $\dfrac{\textrm $ 400\times \textrm 4.4\times \textrm 1}{100}$

Or, x = $ 17.6

So, The interest earn by Monica = x = $ 17.6

Again

The principal amount deposited by Paul in account = $ 500

The rate of interest = 3.6 % at simple interest

The time period = 1 years

Let The interest earn by Paul = $ y

<u>From simple interest </u>

Simple Interest = $\dfrac{\textrm principal\times \textrm rate\times \textrm time}{100}$

Or, $ y = $\dfrac{\textrm $ 500\times \textrm 3.6\times \textrm 1}{100}$

Or, y = $ 18

So, The interest earn by Paul = y = $ 18

∴ As The interest earn by Paul $>$ The interest earn by Monica

Hence from the above calculation it is clear that The interest earn by Monica is less than the The interest earn by Paul , so Monica is wrong Answer

Simplifly the expression 5^0

Angelina_Jolie [31]

ANY number raised to the zero power is ' 1 '.

(This rule is worth memorizing. You'll amaze all of
your friends, especially the ones who don't know
how to do it without running to Google.)

So 5^0 = 1 .

How do I do this problem?

goldenfox [79]

so a quadrilateral is a figure with 4 sides. So looking at the picture I see 5 rhombi and 7 squares. So all together thats 12 quadrilaterals

So to find the ration you have to do:

amount of thing: whole

so in this case it would be

12:24

which you can simplify

normally you'd simplify to 1:2 but that doesn't seem like an option so I'd go with the one closest to that ratio

Which of the following triangle cases may have one, two, or zero solutions?

Lunna [17]

I think the correct answer is B. It is the triangle case SSA that may have one, two, or zero solutions. This case can have either number of solutions but it depends on the sides of the triangle given. Having one solution can be all of the cases except SSS, having 2 solutions can only be applied to SSA.

Equivalent fractions for 9/11, 15/17, and 2/3 using the least common denominator.

TiliK225 [7]

The (small) challenge here is to determine what the LCD is. Since 11, 17 and 3 are all prime, we find the LCD by multiplying them together: 561.

Then 9/11= 459/561; 15/17 = 495/561; and 2/3 = 375/561.
