Answer: A. 18

Step-by-step explanation:

Let the smallest number be x

Hence,

x+(x+2)+(x+4)+(x+6)=60

x+x+2+x+4+x+6=60

4x+12=60

4x+12-12=60-12

4x=48

Divide both parts of the equation by 4:

x=12

x+6=

12+6=

Answer:

x=10

y=25

Step-by-step explanation:

3x-10+5x+30+6x+20=180

14x+40=180

14x=180-40

14x=140

x=10

9x-10=4y-20

9(10)-10=4y-20

90-10=4y-20

80=4y-20

80+20=4y

100=4y

25=y

Find the slope of the line graphed in the diagram and choose the correct answer from the choices below. The two intercepts are (

balandron [24]

Answer:

6/5

Step-by-step explanation:

Using the given points (0, 3) and (-2.5, 0) you can substitute it into the slope formula which is y2-y1/x2-x1

In this case, 3 in the first parenthesis is the y2, while 0 in the second parenthesis set is 0.

so,

= substitute in the numbers for the slope formula: 3-0/0-(-2.5)

= reduce the fraction and you get: 1.2

= convert to simplified fraction to get: 6/5

Hope this helps, I did this on a quiz and got the answer right.

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

So remember that GCFs are greatest common factors, or the greatest number and/or variable that divides 2 or more terms nicely (aka no decimals).

With this, you at least know that a factor of these two numbers is 7, which turns this expression to 7(4 + 10). However, what's inside the parentheses can still be factored out with a GCF of 2. So you can further factor the expression as 2 * 7(2 + 5), which can be simplified to 14(2 + 5), or D. Since 2 and 5 do not have GCFs greater than 1, that is your answer.
