Answer:
0.8 OR 
Step-by-step explanation:
The reciprocal of any number is the number that it multiplies by to equal 1.
The reciprocal can be found by simply converting the number into a fraction and then 'flipping' the fraction as any number multiplied by its reciprocal is 1.
E.g.
No. X/Y * Y/X (its reciprocal) = 1
So, to find the reciprocal of 1.25,we should first convert 1.25 to a fraction.
1.25 = 125/100
Now we just flip 5/4 to get our reciprocal:
= 0.8
Test: 0.8 * 1.25 = 1
The reciprocal of 1.25 (
) is 0.8 ().

1.x2x
+x.4x7
5.036 (sorry the underline function is no longer available)
In the thousandth column we have x +7 and we wind up with a 6 in that column.
Since 7 is already more than 6 that means the only number that will work is 9 and there will be a carry of one into the hundredths place.
1.x29
+x.4x7
5.036
Now let's look at the tenths column. 2 becomes 3 in the answer and there was a carry of 1 from the thousandths so the other number must be a zero
1.x29
+ x.407
5.036 Now I need a number that goes with 4 and puts a zero in the answer.
That number has to be 6 and does cause a carry of one into the ones
place
1.629
+x.407
5.036
Finally (remembering there is a carry of one in the ones place) I have two (1 + 1 carried) toward my five in the answer. I need three more.
Here is the final example:
1.629
+3.407
5.036
Answer:
Below in bold.
Step-by-step explanation:
Standard form is Ax + By = C
where A, B and C are integers and A must be positive.
So the first 2 are already in standard form but the last 2 can be converted to standard form by multiplying each term by -1:
-12x+3y=27
= -1*-12x + -1*3y = -1*27
12x - 3y = -27 is the answer.
The last one is:
24x + 12y = -60.
