Answer:a) L.C.M OF 2,3,5 is 30

THEREFORE=60/30+15/30÷10/30-6/30

=60/30+15/30×30/10-6/30(DMAS)

=60/30+3/2-6/30

=60+45/30 -6/30(ADDITION FIRST THEN SUBTRACTION.

=105/30-6/30

=105-6/30

=99/30

=33/10

b)(3+1/2)÷(2-1/2)=L.C.M IS 2,=(6+1/2)÷(4-1/2)=7/2÷3/2=7/3

Solve for x:

Sonja [21]

$\frac{2x}{5} + 1 = \frac{1}{15}$

---------------------------------------------------------
Take away 1 from both sides
---------------------------------------------------------
$\frac{2x}{5} = \frac{1}{15} - 1$

---------------------------------------------------------
Evaluate the value on the right
---------------------------------------------------------
$\frac{2x}{5} = - \frac{14}{15}$

----------------------------------------------------------
Multiply by 15 on both side
---------------------------------------------------------
$\frac{2x}{5} \times 15 = - \frac{14}{15} \times 15$

---------------------------------------------------------
Evaluate
---------------------------------------------------------
$6x = -14$

---------------------------------------------------------
Divide by 6 on both sides
---------------------------------------------------------
$x = - \frac{14}{6}$

---------------------------------------------------------
Simplify
---------------------------------------------------------
$x = - \frac{7}{3}$

$Answer \: x = - \frac{14}{6} \ or - \frac{7}{3}$

The area of a square is 4 square meters. How long is each side? Please show every step.

inessss [21]

Since you're trying to find the side lenghts of a square, all we need to do is square root the area. So, the square root of 4 (the area) is 2.

So, all of the sides of the square are 2 meters long.
