and 10.6 is already written as a decimal.
Using x and y as the numbers
x+y=25 -------#1
x-y=9 -------#2
Using addition of #1 and #2
x+y+x-y= 25+9
2x+0y=34
2x=34
x=17
Using the value of x and plugging said value into #1 or #2, we can find y
x=17
x+y=25
17+y=25
y=8
OR
x-y=9
17-y=9
-y=-8
y=8
The numbers are 8 and 17
THE ANSWER IS THE SECOND AND THIRD CHOICE.
you move first the number without the variable to the other side with the opposite sign
-0.75p=0.25+2
-0.75p=2.25
then as -0.75 is multiplying you pass it to the other side dividing
p=2.25/-0.75
p=-3
In order to see the probaability of this we need to do an easy calculation here:
If X<span> is the price for the policy, then we proceed like this:
</span>0.982x = 0.0275*<span>31,000
</span><span>
x = 0.0275*</span><span>31,000</span><span>/0.982
Minimum ammount he can expect to pay = $868.12 </span>
