In the problem, the first equation should be represented like this base on the variable given in the problem:
20p + 9t = 44.4
with that equation, the second equation would is given by this formula, in response with the additional number of paperback and textbook
21p + 14t = 51
to get the system equation in getting the mass of each variable, you should subtract the two equation to simplified the formula.
20p + 9t = 44.4
- 21p + 14t = 51
-------------------------
p + 5t = 6.6 // this is the system equation that could be use in getting the mass of each object
Isn’t that considered cheating since it’s a test??
Answer:
21 to 3
70 to 10
Step-by-step explanation:
28÷7 = 4
21÷7 = 3
70÷7 = 10
-2 + 5(3x-4) =19 the answer is x = 2.733
<em>Answer:</em>
<em>II Quadrant</em>
<em>Step-by-step explanation:</em>
<em>Because : </em>
<em>All the angles between 0 and 90 degrees are in the</em><em> I quadrant. </em>
<em>All the angles between 90 and 180 degrees are in the</em><em> II quadrant
</em>
<em>All the angles between 180 and 270 degrees are in the </em><em>III quadrant
</em>
<em>And all the angles between 270 and 360 degrees are in the </em><em>IV quadrant
</em>
<em>
</em>
<em>Since 118° lies between 90° and 180° degrees your answer will be :</em><em> II Quadrant</em>
