7y+5+3y+5=70

10y+10=70

10y=60

y=6

7(6)+5= 42+5= 47

3(6)+5= 18 + 5 =23

47+23= 70

A^-1/[a^-1 - b^-1] + a^-1/[a^-1 + b^-1]
o-na [289]

\dfrac{a^{-1}}{a^{-1}-b^{-1}}+\dfrac{a^{-1}}{a^{-1}+b^{-1}}=a^{-1}\left(\dfrac{a^{-1}+b^{-1}}{(a^{-1}-b^{-1})(a^{-1}+b^{-1})}+\dfrac{a^{-1}-b^{-1}}{(a^{-1}+b^{-1})(a^{-1}-b^{-1})}\right)

=a^{-1}\left(\dfrac{(a^{-1}+b^{-1})+(a^{-1}-b^{-1})}{a^{-2}-b^{-2}}\right)

=\dfrac{2a^{-2}}{a^{-2}-b^{-2}}

=\dfrac{2b^2}{b^2-a^2}

Estimate each the quotient 78÷4 is about _____÷4
KonstantinChe [14]

Answer:

80

Step-by-step explanation:

The trick is to pick something that should be very easy to get an answer to. If you use a calculator, you are not estimating.  80 divide by 4 is like 8 divide by 4 which gives you 2. Then just add a zero. Here's another one you can try. Put your calculator away to do it. 12 chicken noodle  soup cans cost 14 dollars. About how much does 1 can cost

no cheating. No calculator. Is the cost of 1 can more or less than a dollar? If you said more, you've estimated correctly.

Try it the other way. Suppose one can of the soup costs 0.95 cents. How many will 12 cans cost? More or less than 12 dollars.

If you said less, you are estimating correctly. The most useful gift you can take away from any math class is estimation.
