Ummm ....... I think x=80
Answer:
<u>x=1
</u>
Step-by-step explanation:
5x-7=-10x+8
5x=−10x+8+7
5x=−10x+15
5x+10x=15
15x=15
<u>Answer:</u> <u>x=1

Answer:
3.25 seconds.
Step-by-step explanation:
We can use the formula <em>Final Velocity = Initial Velocity + Acceleration * Time </em> to solve this problem.
First, we plug in the values we already know, and then we solve like normal:
1.5 = 0.2 + 0.4*t
1.3 = 0.4 * t
3.25 = t
Therefore, the mosquito accelerated for 3.25 seconds.

What do you think of that L?
Answer:
1.646×10¹¹ km³.
Step-by-step explanation:
From the question given, we obtained the following information:
Radius (r) = 3400 km
Volume (V) =.?
The shape of a planet is spherical in nature. Thus, we shall apply the formula for calculating the volume of a sphere to obtain the volume of Planet Mar as illustrated below:
Radius (r) = 3400 km
Pi (π) = 3.14
Volume (V) =.?
Volume of a sphere = 4/3 πr³
V = 4/3 × 3.14 × (3400)³
V = 4/3 × 3.14 × 3.9304×10¹⁰
V = 1.646×10¹¹ km³
From the calculations made above, the volume of Planet Mar is 1.646×10¹¹ km³
