Answer:
A = - 2 and B = - 8
Step-by-step explanation:
A = - 2 and B = - 8 will create infinitely many solutions for this system of equations
When you add both equations together and both sides are equal then the systems have infinitely many solutions
-2x - y = 8
2x + y = -8
--------------------Add
0 = 0
Both sides are equal 0
Infinitely many solutions
Answer:
The number he thought of was 13
Step-by-step explanation:
Revers the problem
3.5 * 3 = 10.5
10.5 - 4 = 6.5
6.5 * 2 = 13
So, 10% of 40,000 is 4,000 then we add up 40,000 and 4,000 and get 44,000. Then we need to know how much is 10% of 44,000 and it is 4,400. 44,000+4,400= 48,400 and then we just need to repeat this one more time. 48,400+4,840(10% of 48,400)= 53,240. That is the answer))))
While fire clay bricks have a density of 2400 kg/m3, for common red bricks it is 1900 kg/m3 . [
Answer:
the answer should be 
or 11^5
Explanation:
Since there are five 11 in the equation, the answer should be or 11^5
You shouldn't write 161051 as the answer because it is NOT a exponent.
