Answer:
3/2 - 4 = y
Step-by-step explanation:
2y - 3x = -8 original problem
2y -3x + 8 = 0 addition property of equality
-3x + 8 = -2y subtraction property of equality
3/2x - 4 = y division property of equality
Answer:
<u><em>The area increase by 225%</em></u>
<em><u>Step-by-step explanation: </u></em>
<em><u>attachment of a triangle</u></em>
<em><u>The area of a triangle equilateral is calculated with the next formula:</u></em>
<em><u>A=
</u></em>
<em><u>
=
</u></em>
<em><u>
=
*3</u></em>
<em><u>h=
</u></em>
<em><u>h=
</u></em>
<em><u>replacing in the A equation:</u></em>
<em><u>A=
</u></em>
<em><u>A=
</u></em>
<em><u>Now each side increse by 50% ⇒ a=1.5a</u></em>
<em><u>A=
</u></em>
<em><u>A=
</u></em>
<em><u>A=2.25 *
</u></em>
<em><u>It means that the area incrase by 225%</u></em>
Y = 55/10x + 50 is the equation to represent this situation
Yes it can be guaranteed to get a sum of 7 once
