Answer:

Step-by-step explanation:

Simplifying 4y + -70 = 12y + 2

Add -12y to each side of the equation. -70 + 4y + -12y = 2 + 12y + -12y

Add 70 to each side of the equation. -70 + 70 + -8y = 2 + 70

Divide each side by -8.

So y = -9 is your answer.

Hope I Helped!!!

Scilla [17]

Answer:

x=175/3

Step-by-step explanation:

700/1200=x/100

Simplify to 7/12

7/12=x/100

Multiply both sides by 100

7/12×100=x

Simplify 7/12 ×100 to 700/12

700/12=x

Simplify 700/12 to 175/3

175/3=x

Switch Sides x=175/3

hope that helps you

*brainliest for best answer thank you* Solve for b.

Hello from MrBillDoesMath!

Answer:

The fourth choice, b = +\- sqrt( sg + a^2)

Discussion:

s = (b^2 - a^2)/g => multiply both sides by "g"

sg = b^2 - a^2 => add a^2 to both sides

sg + a^2 = b^2 => take the square root of each side

b = +\- sqrt( sg + a^2)

which is the fourth choice.

Thank you,

Which value of v makes 12=12+\defray{v-8}{2}12=12+ 2 v−8 12, equals, 12, plus, start fraction, v, minus, 8, divided by, 2, end

ollegr [7]

The value of $v$ which makes the statement true is 8.

Explanation

The given statement is: $12= 12+ \frac{v-8}{2}$

For finding the value of $v$ which makes the statement true, we will just solve the above equation for $v$ .

First we will multiply both sides by 2 and then solve for $v$ . So.......

$12*2=(12+\frac{v-8}{2})*2\\ \\ 24=24+v-8\\ \\ 24=v+16\\ \\ v=24-16=8$

Thus, the value of $v$ which makes the statement true is 8.

A group of students is arranging squares into layers to create a project. The first layer has 6 squares. The second layer has 12

kkurt [141]

Answer:

$a_n=6n$

Step-by-step explanation:

This is an example of an arithmetic sequence that is that the following term is obtained by adding or substracting a number called difference the formula for this sequence is:

$a_n=a_1+d(n-1)$

In this case your first term is:

$a_1=6$

and your difference is

$d=6$

substituting these values we have that

$a_{n}=6+6(n-1) \\a_n=6+6n-6\\a_n=6n$

Help please! i need to find the restrictions to this expression

jarptica [38.1K]

Answer:

x = 7, x = $\frac{-1}{5}$

Step-by-step explanation:

A restriction can only be found in the denominators and this is when x is a certain number that when plugged in, makes the expression 0 (this makes it undefined, which you cannot have).

Since we are only looking at the denominator, you can just ignore the numerator:

(x - 7) (5x + 1)

To find the restrictions, you must set them equal to 0:

x - 7 = 0

5x + 1 = 0

Then, solve:

x - 7 = 0 5x + 1 = 0

+ 7 + 7 - 1 - 1

________ ________

x = 7 5x = -1

x = $\frac{-1}{5}$

If you plug these numbers in, the total outcome would come out to be 0, making the expression undefined, proving that these are the restrictions of the expression.
