Answer:

1.66 (appx)

Step-by-step explanation:

According to BODMAS rule , we should solve division operation in the expression first , then we'll finish the addition opearation .

0.65 \div 0.75 + 0.8

=  >  \frac{65}{100}  \div  \frac{75}{100}  +  \frac{8}{10}

=  >  \frac{65}{100} \times  \frac{100}{75}   +  \frac{8}{10}

=  > \frac{13}{15}  +  \frac{8}{10}

=  >  \frac{(13 \times2) + (8 \times 3) }{30}

=  >  \frac{50}{30}  =  \frac{5}{3}  = 1.6666.........

What is the solution to the system of equations below? Y=-1/4x+2 and 3y=-3/4x-6
fgiga [73]

<u>Answer:</u>

There are infinite solutions to the system of equations given

<u>Solution: </u>

The given equations given are,

y=-\frac{x}{4}+2------ (i)

3 y=-\frac{3 x}{4}-6---- (ii)

Now putting the value of (i) in (ii) we get,

3 \times\left(-\frac{x}{4}+2\right)=-\frac{3 x}{4}-6

\Rightarrow-\frac{3 x}{4}+6=-\frac{3 x}{4}-6

\Rightarrow\frac{3 x}{4}-\frac{3 x}{4}=-12

\Rightarrow0 \times x=-12

\Rightarrowx=(\frac{-12}{0})=\infty

So, there are <em>infinite solutions</em> to the system.

What is the surface area of a cube that measures 3 cm​
kifflom [539]

Answer: Surface area= 54

Step-by-step explanation:

To find the surface area of a cube you do 6 times s^2

S is the side length. In this case that is 3 cm. S^2 is 9

So now you do 6 times 9, and that is 54.

So, the surface area is 54.

List the integers that satisfy both these inequalities.
alekssr [168]

Answer: -12 < x < -\frac{9}{2}

<u>Step-by-step explanation:</u>

2x + 9 < 0    and      x > -12

2x       < -9

 x        < -\frac{9}{2}


Since it is an "and" statement, x is between -12 and -\frac{9}{2}, so -12 < x < -\frac{9}{2}

Graph: -12 o-----------------o -\frac{9}{2}

Interval Notation: (-12, -\frac{9}{2})
