Answer:
(2.4, -1.2)
Step-by-step explanation:
Start by moving the x and the y to the same side and moving the number across the equal sign in both equations. We should now have y-0.45x=-2.3 and 2y+4.2x=7.8. We can use the elimination method by multiplying the first equation by -2 to get -2y+0.9x=4.6 and 2y+4.2x=7.8. From there, add the two equations together, eliminating y (-2+2=0). We now have 5.1x=12.4; divide both sides by 5.1 to get x=2.4. Then, in any of the two equations, let's use y-0.45x=-2.3, substitute x with 2.4. Now we have y-1.08=-2.3. Add 1.08 to both sides to get y=-1.22; round that to the nearest tenth to get -1.2.
Answer:
3526
Step-by-step explanation:
4300×3%=129
129×6=774
4300_774= 3526
HI THERE YO!!!!!!"Use Pythagorean Theorem to solve (a right triangle with the base being one of the side lengths and the height being the other side length. a^2 + b^2 = c^2
64^2 + 100^2 = length of diagonal ^2
4096 + 10000 = 14096
The length of the diagonal is the square root of 14096 or 118.727 meters (rounded to the thousandths place). "

50 years ... 2.5 degrees
1 year ... x degrees = ?
If you would like to know what is the rate of change in worldwide temperatures per year, you can calculate this using the following steps:
50 * x = 2.5 * 1
50 * x = 2.5 /50
x = 2.5 / 50
x = 0.05 degrees per year
Result: The rate of change is 0.05 degrees per year.
Answer:
240 cubic inches
Step-by-step explanation:
Okay first you multiply length by width by height to get the volume which is:
15*8*6= 720
Braking it down:
15*8= 120
120*6= 720
So then you divide 720 by 3 because the 720 is the total value of the box but we just want to know what the volume of how much dirt is there:
720/3= 240 (Check on a calculator if you want to ;D)
So your answer is 240 cubic inches of soil in the flower box
<em>Hope this helps :D </em>
