Answer:

-35

Step-by-step explanation:

Using the rules of BIMDAS, division goes before addition, hence -20/2 which gives you -10

Put that in the equation and it would be:

-10 + (-15)

A negative and a positive make a negative hence, you could simply write it as:

-10 - 15

Which equals -35

Question 10 (1 point) Solve for x. 1/2+x/6=4/3

jek_recluse [69]

Answer:

The value of x for the given expression is 5 .

Step-by-step explanation:

Given expression as

$\dfrac{1}{2}$ + $\dfrac{x}{6}$ = $\dfrac{4}{3}$

Now, arrange the equation

So, $\dfrac{x}{6}$ = $\dfrac{4}{3}$ - $\dfrac{1}{2}$

Taking L.C.M on right hand side

Or, $\dfrac{x}{6}$ = $\dfrac{8 -3}{6}$

Or, $\dfrac{x}{6}$ = $\dfrac{5}{6}$

Or, x = $\frac{5\times 6}{6}$

∴ x = 5

So, The value of x = 5

Hence,The value of x for the given expression is 5 . Answer

Step-by-step explanation:

a) 24.7×52.3=1291.81

On rounding off to 3 significant digits we get

1290

$\sqrt{ {42}^{2} - {28}^{2} }$

$\sqrt{1764 -784 } = \sqrt{980}$

=31.304951

On rounding off to 5 significant figures we get

=31.305

$\sqrt[3]{78} = 4.27265$

On rounding off to 2 significant figures we get

=4.3

Hence required answers

a)1290

b)31.305

c)4.3

I hope it helped you
