Step-by-step explanation:
1. move the decimal to make the numbers whole
0.25 - move to the right 2 times - 25
0.044 - move to the right 3 times - 44
2. Multiply 25 * 44 = 1,100
3. Add decimal
you moved the decimal 6 times in total for both numbers...so move the decimal 6 times starting from right.
<u>Answer - 0.01100 or 0.011</u>
Answer:700

Answer:

Step-by-step explanation:
We want to find the value of x that satisfies both
- 9x + 4y = 8
and
-3x-y= 4
given the same value of y.
This is the x-value of the point of intersection of the graph of the two lines.
We make y the subject of the bottom equation to get:
y=-3x-4
We substitute y=-3x-4 into the top equation to get:
-9x+4(-3x-4)=8
Expand to get:
-9x-12x-16=8
Group like terms

-21x=24
