Normaly it's 1 cause 7÷0.01=700 and 7÷0.1=70.
Answer:
Step-by-step explanation:
If you need to do this by graphing, you need to change the format of each equation into slope intersect form
start with 3x-2y=-24
-2y=-3x-24
y=-3/2x+12
To graph this, the y intersect (where it crosses the y axis) is 12 and from there the slope is -3/2
For the next equation,
-3x-y=6
-y=3x+6
y=-3x-6
So the y intersect is -6 and the slope is -3.
Once you graph both of these, the point where both lines cross AKA the intersecion is the solution to the problem.
Answer:
x=8
Step-by-step explanation:
-4 = 12 - 2x
when plus 12 goes to the left hand side it changes its sign so,
-4 -12 = -2x
- * - is plus so add 4 and 12 but keep the sign - because 12 is the greatest number and its sign is -
-16=-2x
when -2 comes to the left hand side it changes its from multiplication to division.So,
-16/-2=x
8=x
we will get positive 8 because minus and minus also gets cancel.

Answer:
<h2>53 and 47.</h2>
Step-by-step explanation:
let x and y represents the two uncknown numbers
then
x+y=100
x-y=6
then
2x=100+6=106
2y=100-6=94
then
x=106/2=53
y=94/2=47.
