Simplify the expression -3 ÷ (-2/5

Harlamova29_29 [7]

Answer:

7.5

Step-by-step explanation:

To solve this expression, we can use PEMDAS or order of operations.

Parenthesis

Exponents

Multiplication>Division (Depends on which comes first from left to right)

Addition>Subtraction (See Multiplication>Division)

So First, lets solve the Parenthesis. -2/5=-.4

So now, our equation is -3/-.4

There is no exponents or multiplication, so lets just Divide.

-3/-.4=7.5

The solution is 7.5

Hope this helps!

Solve the system thank you

Lunna [17]

Answer:

infinite solutions

Step-by-step explanation:

replace x with 3y + 9 in the second equation

9 - (3y + 9) = -3y ➡ 9 -3y -9 = -3y ➡9-9 = 3y-3y ➡ 0 = 0

this means whatever numver you write instead of y there will be a solution.

Zaid and Matias, two farmers, constructed a 792 foot fence around their very large garden. Zaid agreed to construct 20% more of

likoan [24]

Answer:

$1.2x +x =792$

$2.2x =792$

And we got finally:

$x =\frac{792}{2.2}= 360 ft$

And the amount for Zaid would be 1.2*360 ft= 432ft

So then Zaid construc 432 ft and Matias 360 ft

Step-by-step explanation:

For this case we know that Zaid and Matias, two farmers, constructed a 792 foot fence around their very large garden so then the total is represented by 792 ft

We also know that Zaid agreed to construct 20% more of the fence than Matias did. Let's assume that the amount that construct by Matias was x then the amount constructed by Zaid would be 1.2 x representing 20% more than Matias and we can set up the following equation:

$1.2x +x =792$

$2.2x =792$

And we got finally:

$x =\frac{792}{2.2}= 360 ft$

And the amount for Zaid would be 1.2*360 ft= 432ft

So then Zaid construc 432 ft and Matias 360 ft
