Answer:
yup and yup
Step-by-step explanation:
also 1. is yup and yup
Math:
Step #1: Distribute
<span><span>(1.8)(1.5x)+<span>(1.8)(−2.6y)</span></span>+(−2.5)(2x)</span>+<span>(−2.5)<span>(1.5y<span>)
</span></span></span>
you'd get: <span><span><span><span>2.7x+ −4.68y </span>+ </span>−5x </span>+ </span>−<span>3.75<span>y
Step #2: Combine like terms
</span></span><span>(<span>2.7x + <span>−5x</span></span>)</span>+<span>(<span><span>−4.68y </span>+ <span>−3.75y</span></span><span>)
</span></span><span>
</span><span>Your answer:
</span><span>−<span>2.3x</span></span>−<span>8.43<span>y</span></span>
function notation is the way a function is written. It is meant to be a precise way of giving information about the function without a rather lengthy written explanation.
1)
We calculate the total number of new light fixtures.
Total number of new light fixtures=(24 new fixtures/1 floor)(4 floors)=
=96 new fixtures.
2)
We calculate the total number of work hours
20 minutes=20 minutes * (1 hour/60 minutes)=1/3 hour.
1 electrician-----------1/3 hour----------1 new fixture
2 electricians---------- x ------------96 new fixtures
1 elec.*1/3 hour*96 nex fixtures=2 elect. * x * 1 new fixture.
x=(1 elec. *1/3 hour * 96 nex litght fixtures) / (2 elect.* 1 new fixture)=
=16 hours.
3)
We calculate the total number of days that it take two electricians to complete the installations.
1 day-------------8 work hours
x------------------16 work hours
x=(1 day* 16 work hours) / (8 work hours)=2 days
Answer: 2 days.
Same denominator.
Add only the numerators.
5/12 + 8/12
13/12~~~
