Answer:
X1 = 34
X2 = -42
Step-by-step explanation:
Given the simultaneous equations
X1 + X2 =-8 .... 1 * 3
3X1 +2X2 = 18 .... 2 * 1
______________________
3X1 + 3X2 = -24
3X1 +2X2 = 18
Subtract
3X2 - 2X2 =-24 - 18
X2 = -42
Substitute X2 = -42 into 1
X1 + X2 = -8
X1 - 42 = -8
X1 = -8+42
X1 = 34
Hence the solution to the system of equation is (34, -42)
0.2 is rounded to the nearest tenth
First we find the volume of the triangular prism.
We find the area of the triangle, then we multiply that by the height.
So 7*6/2= 42/2=21
21*10= 210
Then if all the dimensions add another foot on to them then you get: 7, 8, and 11.
Then you do the same thing to find the area of this rectangular prism.
7*8/2=56/2=28
28*11= 308
Now, we calculate the growth from 210 to 308 in this proportion: 308/210=x/100
Solving it we get (cross multiplying):
210x=30800
x=146 2/3 or 146.66 percent increase.
I hope this helps!
Answer:
-1
Step-by-step explanation:
Since 34 is an even number, we can factor a 2 out of the exponent of your problem, like this:
i34=(i2)17.
But, i2=-1, so your problem becomes:
-117.
This means, multiply -1 by itself 17 times, to get -1
(Remember, -1 raised to an odd power is always -1, so -117=-1.)
The final answer is:
i34=-1
Answer:
1900
Step-by-step explanation:
570/12 = The rate at which James earns money, or $47.5
47.5 × 40 = 1900 Because you wan to know the value after 40 days
