Answer: x=12

Step-by-step explanation: x - 5 =12 the inverse operation of subtracting is adding so add 5 to both sides and you are left with x=7 + 5 the 5 on the left side cancels each other out so now all you do is add 5 to 7 and your left with x = 12

Toa has 4 dimes a 12 nickels.Gail has 2 dimes and 3 nickels. What would be the ratio of dimes to nickels if they put these toget
Free_Kalibri [48]

Answer:

2 : 5

Step-by-step explanation:

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

We are to determine the ratio of dimes to nickels

total sum of nickels = 3 + 12 = 15

total sum of dimes = 4 + 2 = 6

6 : 15

three can divide each of the numbers

2 : 5

Complete the square to transform the quadratic equation into the form (x – p)2 = q.
ryzh [129]

The transformed equation is:

(x-3)^2 = 23

Step-by-step explanation:

We have to convert the equation in the form

(x-p)^2 = q

Given equation is:

x^2-6x-8 = 6

Adding 8 on both sides

x^2-6x-8+8 = 6+8\\x^2-6x = 14

In the given equation

a = x

b= ?

So,

2.x.b = 6x\\b =\frac{6x}{2x}\\b = 3\\

So 3^2 will be added on both sides

(x)^2-6x+ (3) = 14+ (3)^2\\(x-3)^2 = 14+9\\(x-3)^2 = 23

Hence,

The transformed equation is:

(x-3)^2 = 23

What is the distance between (–6, 2) and (8, 10) on a coordinate grid?
raketka [301]

Answer:

Distance = Square Root [(x2 -x1)^2 + (Y2 -Y1)^2]

Distance = Square Root [(8 --6)^2 + (10 -2)^2]

Distance = Square Root [14^2 + 8^2]

Distance = Square Root [196 +64]

Distance = Square Root [260]

Distance = 16.1245154966

Find the sum of the following series.<br><br><br> PLEASE SOMEONE HELP!!!
Dmitry [639]

The given sum for n = 1 to n = 15 is equal to 255, so the correct option is B.

<h3>How to find the sum of the given series?</h3>

We want to find the sum of the series whose elements are of the form:

(2n + 1)

From n = 1 to n = 15.

Then our sum will be:

(2*1 + 1) + (2*2 + 1) + ... + (2*15 + 1).

3 + 5 + ... + 31

This is the sum of all odd numbers in the interval [3, 31]

Which gives:

S = 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25 + 27 + 29 + 31 = 255

So the correct option is B.
