Answer:

D. 6, 6 $\sqrt{3}$ , 12

Step-by-step explanation:

the Pythagorean Theorem states that $a^{2} +b^{2} =c^{2}$

so,

$6^{2} =36\\(6\sqrt{3}) ^{2} =108\\12^{2} =144\\36+108=144$

3(x - 5) = 30 I dont know how to solve this

Anastaziya [24]

Answer:

x=15

Step-by-step explanation:

3(x-5)=30

First, you would distribute the three to the x and the negative five.

3x-15=30

Then you would add 15 to the 15 to cancel it and to the 30 to make it even.

3x-15=30

+15=+15=

3x=45

Finally, you would divide 3 into both sides, cancelling out the three and fiving you,

x=15

Hope this helped!

Latoya's annual salary is $26,000. A total of $7352.24 will be deducted for taxes and health insurance. She will receive her pay

Anna71 [15]

Step-by-step explanation:

Lets translate this word problem into math.

"Latoya's annual salary is $26,000" = We start with the number 26,000

"A total of $7352.24 will be deducted for taxes and health insurance" = It's the number we started with "deducted" (minus) 7352.24

"She will receive her paycheck monthly in 12 equal installments" = Our number will be divided by 12

"How much will she get paid with each paycheck?" = "Find answer pls thx"

To put it all together...

$\frac{26,000-7,352.24}{12}$

Now all we have to do is solve!

$\frac{26,000-7,352.24}{12}$

Subtract.

$\frac{18,647.76}{12}$

Divide.

$1,553.98$

Answer:

Latoya will get paid $1,553.98 with each paycheck.

Swap the Xs and the numbers, changing sign

2x+14x=9+1

Do calculations

16x=10

Find the distance between the points (-7,-6) and (5,-6) .

PilotLPTM [1.2K]

Answer:

12 units

Step-by-step explanation:

We are given these two points, (-7,-6) and (5,-6), and we are to find the distance between them.

We know the formula for finding the distance between two points:

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

So putting in the values of the given coordinates in the above formula to get:

Distance = $\sqrt{(5-(-7))^2+(-6-(-6))^2}$ = $\sqrt{144 + 0} =12$

Therefore, the distance between the two given points is 12 units.
