First, we have the two fractions to have the same denominator.

7/8

3/4 --> 6/8

Now this is easier.

7/8-1/x=6/8

So with that done you can easily see that 7/8-1/8=6/8 or 3/4

So x=8

Hope this helps!

Solve for b2: A=1/2h(b1+b2)

balandron [24]

Answer:

Step-by-step explanation:

$A = \frac{1}{2}h(b_{1} + b_{2})$

First let's multiply both sides by 2 to remove the $\frac{1}{2}$ fraction:

$2A = h(b_{1} + b_{2})$

Next, let's divide both sides by $h$ :

$\frac{2A}{h} = b_{1} + b_{2}$

Finally, let's subtract $b_{1}$ from both sides:

$b_{2} = \frac{2A}{h} - b_{1}$

If 80% of M is equal to 50% of N and N≠0, what is N/M equal to?

erastova [34]

Whatever% of anything is just (whatever/100) * anything.

thus, what is 80% of M, well is just (80/100) * M,

what is 50% of N? well is just (50/100) * N.

we know they're both equal, thus

$\bf \cfrac{80}{100}M=\cfrac{50}{100}N\implies \cfrac{8M}{10}=\cfrac{5N}{10}\implies \cfrac{4M}{5}=\cfrac{N}{2}
\\\\\\
\cfrac{4\cdot 2}{5}=\cfrac{N}{M}\implies \cfrac{8}{5}=\cfrac{N}{M}$
