How do you solve this 2 step equation: 8+b/-4=5

1 answer:

3 0

I'm going to rewrite the equation assuming this is the correct form:
$8 - \frac{b}{4} = 5
\newline
-8 + 8 - \frac{b}{4} = 5 - 8
\newline
(-4)\cdot -\frac{b}{4} = -3 \cdot (-4)
\newline
b = -12$

For Aaron

$A=\frac{2}{10} *5940$

$A=1188$

For Beth

$B=\frac{3}{10} *5940$

$B=1782$

For Charlie

$C=\frac{2}{10} *5940$

$C=2970$

Check answer

$A+B+C=5940\\1188+1782+2970=5940$

Write this number in standard form. 300+80+0.9+0.06+0.001

Lina20 [59]

Hey there! I'm happy to help!

First, let's add the hundreds and the tens.

300+80=380

We see that there is nothing in the ones place, so we keep our ones place 0 and we move onto adding the tenths.

380+0.9=380.9

We add the hundredths.

380.9+0.06=380.96

And finally, we add the thousandths.

380.96+0.001=380.961

Therefore, this number in standard form is 380.961.

Have a wonderful day! :D
