Answer:

A) -2

Step-by-step explanation:

3x+5(4x-3)= -61

(Distrbute the 4)

3x+20x-15= -61

(Add like terms)

23x-15= -61

(Add opposite)

23x+(-15)= -61

(Do inverse opporation and add 15 which cancels 15 and add it to -61)

23x= -46

(Divide 23 to both sides)

X= =2

3x + 5(4x-3) = -61
3x + 20x - 15 = -61
23x - 15 = -61
23x divided by -46
the answer is A) -2

Averi was trying to factor 4x2 + 20x - 16. She found

hichkok12 [17]

Answer:

The width will be $x^{2} +5x-4$

Step-by-step explanation:

Thinking process:

Let the model be:

$4x^{2} +20x-16$

factoring out 4 gives:

$4(x^{2} +5x-4)$

Factorizing the expression in the parentheses gives:

$4(x^{2} +5x-4)$

Therefore, since the expression in the parentheses cannot be factorized further, the expression is:

$length = 4 units\\width = x^{2} +5x-4$

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

Alexis, Becca, and Cindy do volunteer work at Adopt-a-Pet Animal Shelter. They worked a total of 285 hours at the shelter last s

swat32

Alexis worked for 59 hours, Becca worked for 74 hours and Cindy worked for 152 hours.

Step-by-step explanation:

Given,

Total hours worked by three of them = 285 hours

Let,

x represent the hours of Alexis.

y represent the hours of Becca.

z represent the hours of Cindy.

According to given statement;

x+y+z=285 Eqn 1

Alexis worked 15 hours less than Becca.

x = y-15 Eqn 2

z = 2y+4 Eqn 3

Putting value of x and z from Eqn 2 and 3 in Eqn 1

$(y-15)+y+(2y+4)=285\\y-15+y+2y+4=285\\4y-11=285\\4y=285+11\\4y=296$

Dividing both sides by 4

$\frac{4y}{4}=\frac{296}{4}\\y=74$

Putting y=74 in Eqn 2

$x=74-15\\x=59$

Putting y=74 in Eqn 3

$z=2(74)+4\\z=148+4\\z=152$

Alexis worked for 59 hours, Becca worked for 74 hours and Cindy worked for 152 hours.
