Answer:
Step-by-step explanation:
10 % = 10/100 = .1
.1 % = .1 /100 = 1/1000 =.001
.1 ÷.001 =
10/100 ÷ 1/1000
Copy dot flip
10/100 * 1000/1 =
10000/100
100
Now we need to change it to percent
Multiply by 100%
100 * 100 %
10000%
Answer:
2 11/32 or 75/32
Step-by-step explanation:
2 3/8 - 1/4 x 1/8= 2 3/8 - 1/32= 19/8- 1/32= 76/32 - 1/32= 75/32= 2 11/32
Answer:
x=25°
Step-by-step explanation:
Since this is a line we can say that 2x+10°+4x+20°=180°
6x+30°=180°
6x=150°
x=25°
Answer:
A (-5,2)
Step-by-step explanation:
5x+y=-23
7x-3y=-41
3×(5x+y)=3×(-23)
15x+3y=-69
<u>+</u><u>7x-3y</u><u>=</u><u>-41</u>
<u>22x</u>=<u>-110</u>
22. 22
x=-5
5x+y=-23
5(-5)+y=-23
-25+y=-23
<u>+25</u><u>.</u> <u>+25</u>
y=2
When using elimination you add both equations together so that one variable cancels out the other. In this situation, y can be the variable. You must get the y-variables to cancel out leaving just the x- variables to solve for.
