Answer:
-7
Step-by-step explanation:
To find x, substitute the values and solve.
R = 2x + 9y
It becomes:
2x + 27 = 13
Rearrange and solve
2x = -14
x = -7
Hope this helps
Most
importantly, while including divisions with various denominators, the initial
step says that we should change these portions so they have "a similar
denominator" .Here are the means for including divisions with various
denominators .Construct each portion with the goal that the two denominators
are equivalent. Keep in mind, while including divisions with various
denominators, the denominators must be the same.
So
we should finish this progression first.
<span>a. Re-compose every proportionate division
utilizing this new denominator </span>
<span>b. Now you can include the numerators, and
keep the denominator of the proportionate divisions. </span>
<span>c. Re-compose your answer as a streamlined
or decreased division, if necessary. </span>
We know this sound like a great deal of work,
and it is, yet once you see completely how to locate the Common Denominator or
the LCD, and manufacture proportional parts, everything else will begin to
become all-good. Thus, how about we set aside our opportunity to do it.
Solution:
5b/4a + b/3a -3b/a
=15b/12a + 4b/12a – 36b/12a
= -17b/12 a
Or
<span>= - 1 5b/12a in lowest term.
</span>
6,395.00 x 2 = 12,790
So $12,790 for the emerald rings.
5,314.00 x 2 = 10,628
So $10,628 for the pearl bracelets.
12,790 + 10,628 = 23,418
So $23,418.00 for all four pieces of jewelry.
Hope it helps!
Answer:
A, C, and D all do because if you were to hold a pencil up vertically, the line would only intersect it once, if it intersected more, it is not a function
Step-by-step explanation:
