Write -1.64 as a fraction in simplest form

Mashutka [201]

To write the following as a fraction, we will;

First write the decimal over 1

That is;

$\frac{-1.64}{1}$

Then multiply the numerator and the denominator by 100

$\frac{-1.64\text{ }\times100}{1\text{ }\times100}$ $\frac{-164}{100}$

Now, go ahead and reduce the fraction

$=-\frac{41}{25}$ $=\text{ -1}\frac{16}{25}$

Find the length of each side of the polygon for the given perimeter

butalik [34]

Answer:

choice number 2) 10 in, 18.5 in 31.5 in

Step-by-step explanation:

we collect and evaluate the like terms.like terms means the ones that can be evaluated. like 2y and 7y are like terms. they either can be added or subtracted to get an answer . 7y-2y =5y. but you cant subtrac or add 7y with 5 because they are not like terms.

2y +1 + 7y + 3y + 5 = 60

(2y+7y+3y)+(1+5) = 60

12y + 6 = 60

The 6 crosses the equal sign to the other side because of like terms.And becomes a minus

12y = 60 - 6

12y = 54

y = 4.5

so,

2y +1= 2 x 4.5 + 1 =10

7y = 7 x 4.5 = 31.5

3y + 5= 3 x 4.5 + 5 =18.5

Answer is 10 in, 18.5 in, 31.5 in

If you need any clarification or more explanation pls do mention at the comment section so that i can help more thx

Hope this helps and if it does pls mark as branliest answer thx

Solve the linear programming problem.<br><br> Maximize and minimize<br><br> z=4x+5y

Mrrafil [7]

Answer:

Step-by-step explanation:

The objective function is;

$z(x,y)=4x+5y$

The vertices of the feasible region are (0,4), (4,2) and (5,0) and (0,0)'

We substitute the vertices into the objective function to get;

At (0,4);

$z(0,4)=4(0)+5(4)=20$

At (0,4);

$z(4,2)=4(4)+5(2)=26$

At (5,0);

$z(5,0)=4(5)+5(0)=20$

At (0,0);

$z(0,0)=4(0)+5(0)=0$

Therefore the maximum value is 26

Solve for n: 6n+12=6

arlik [135]

Hey there! :)

6n + 12 = 6

Isolate our given variable.

We can do this by subtracting both sides by 12.

6n + 12 - 12 = 6 - 12

Simplify.

6n = -6

Divide both sides by 6.

6n ÷ 6 = -6 ÷ 6

Simplify.

n = -1

~Hope I helped!~
