Answer:
<h2>
</h2>
Step-by-step explanation:
<h3>
</h3>
<u>First of all multiply through by 7</u>
We have
<h3>
</h3>
<u>Expand the terms in the bracket</u>
That's
<h3>
</h3>
<u>Add 16x to both sides</u>
That's
<h3>
</h3>
<u>Divide both sides by 30</u>
We have the final answer as
<h3>
</h3>
Hope this helps you
Ok so one way is to list the multiplues of 9 close to thtat
first use a caltulator to find out how much more we need
160/9=17.777777
that is 17.7777 nine's
so round up
18
18 is even
odd times even=even
18 must be odd
18+1=19
9 times 19=171
the answer is 171
Answer:
a=21
AB=23.9
BC=19.5
CD=(23.9)
AD=19.5
Step-by-step explanation:
Each pair of parallel sides are equal in a parallelogram. Sense both pairs use the same variable we can just choose the easiest to solve which would be:
a-1.5=19.5
add 1.5 to both sides
a=21
now substitute 21 in for a in each equation.
AB=CD so
AB=23.9
BC=AD so
BC=19.5
CD=(21)+2.9 so
CD=(23.9)
AD is given so
AD=19.5
Answer:
point a is positive but point b is negative
The answer would be X =90
