Answer:

Step-by-step explanation:

$-2\dfrac{1}{3}-1\dfrac{1}{3}=-2\dfrac{1}{3}+\left(-1\dfrac{1}{3}\right)=-\left(2\dfrac{1}{3}+1\dfrac{1}{3}\right)\\\\=-\bigg[(2+1)+\left(\dfrac{1}{3}+\dfrac{1}{3}\right)\bigg]=-\left(3+\dfrac{1+1}{3}\right)\\\\=-3\dfrac{2}{3}$

7. For homework Javier has to solve the equation below.

cricket20 [7]

Answer:

C 10⁴

Step-by-step explanation:

The given equation is

$7.75n = 77500$

Javier has to solve for n

He can multiply through by 100 to get;

$775n = 7750000$

He can now divide through by 775 to obtain:

$n = \frac{7750000}{775}$

He can now easily simplify to get:

$n = 10000$

We rewrite as a power to get:

$n = {10}^{4}$

Solve using square roots 3x^2+25=73

seropon [69]

Heya !

Given expression -

$3 {x}^{2} + 25 = 73$

Subtracting 25 both sides ,

$3 {x}^{2} + 25 - 25 = 73 - 25 \\ \\ 3 {x}^{2} = 48$

Dividing by 3 on both sides ,

$\frac{3 {x}^{2} }{3} = \frac{48}{3} \\ \\ {x}^{2} = 16$

Therefore ,
$x = + \: 4 \: \: \: \: or \: \: - 4 \: \: \: \: \: \: \: Ans.$
