Step-by-step explanation:
<h3><em><u>First</u></em><em><u> </u></em><em><u>Equation</u></em><em><u>:</u></em></h3>
-4x - 8 = 5x + 10
=> 5x + 10 = -4x - 8
=> 5x + 4x = -10 - 8
=> 9x = -18
=><em><u> x = - 2 (Ans)</u></em>
<h3>
<em><u>Second</u></em><em><u> </u></em><em><u>Equation</u></em><em><u>:</u></em></h3>
5x + 2 = 12
=> 5x = 12 - 2
=> 5x = 10
=> <em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Answer:
140$
Step-by-step explanation:
yooouuuuuu
1.You can convert them so that they have equal denominators. Then, the numerator can help you decide.
2. Convert them into decimals and compare.
3. Sketching out the fraction that represents wholes and parts.
Here, the numerator of 5/4 was larger than the denominator, unlike 9/10. Subsequently, you can infer that 5/4>9/10
With what are you really confused about
When the balloon reaches the ground a(t) will be zero
the time when it reaches the ground can be calculated as follows
210 - 15t = 0
t = 210/15 = 14 minutes
