The expression equivalent to the fort is a) 4(n-3) -6n, if you so the math for the first one do what is inside the parenthesis first. (think PEMDAS) Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. So the first thing it gives you is -6n +(-12) Well, a negative + a negative = a negative! So, -6+-12= -18, then add your caroable. So, -18n. Now, you add -18n with what you have left so 4n -18+4 is -14n. So, if you do answer a) (n-3) = (1n-3)= (1-3) =-2. -2×4=-8n because a negative × a positive = a negative because they have different signs. From there you have -8n - (6) Instead of subtracting you just add a negative So, you would rewrite your problem as: -8n+(-6)= -14n the same thing you got as your orginal. Hope tj
his helped! Don't forget about adding you variables and PEMDAS!! Also d po not forget about your positive a negative rules!!!

Using the number line shown, subtract 1 2/6 from 4 4/6.

Soloha48 [4]

Hey there!

$\bold{1\frac{2}{6}-4\frac{4}{6}}$

$\bold{1\frac{2}{6}=1\frac{1}{3}=\frac{4}{3}}$
$\bold{4\frac{4}{6}=4\frac{2}{3}=\frac{14}{3}}$
Problem becomes: $\bold{\frac{4}{3}-\frac{14}{3}}$
To solve our new problem $\uparrow;\downarrow$
$\bold{4-14=-10}$
The $\bold{3's}$ stay the same because the same
$\bold{\rightarrow=\frac{-10}{3}}$
$\boxed{\boxed{\bold{Answer:\frac{-10}{3} (or)=-3\frac{1}{3}}}}$

Good luck on your assignment and enjoy your day!

About 5 out of 10 people entering a community college need to take a refresher mathematics course. If there are 970 entering st

Ksenya-84 [330]

Answer:

"6 out of 10 people" means the ratio of class:no_class is 6:4

990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.

99(6) = 594 ----------- probably class

99(4) = 396 ------------------ probably no class

Total = 990
