This week the number of lawns "times" 25 and his allowance = $345
Therefore...
25x + 20 = 345
- 20 -20
25x = 325
Now divide both sides by the coefficient (25)... and that will be the number of lawns he mowed.
Hope this helps!

8x10^-6
Because the decimal point must be moved left 6 places in order to be equal when multiplied by the whole number the 10 must be to the -6th
Answer: Third option is correct.
Step-by-step explanation:
Since we have given by
Event A: the red die shows 1
Event B : the numbers add to 4
Event C: at least one of the numbers is 3
Event D : the numbers do not add to 9.
D' means the number add to 9.
We need to write the following statement in symbolic form:
Either the numbers add to 9 or the red die shows a 1.
So, it becomes,

Number of elements in D'∪A = 1.
Hence, Third option is correct.
Whole numbers greater than zero are called positive integers<span>. Whole numbers less than zero are called </span>negative integers<span>. The </span>integer<span> zero is neither </span>positive<span> nor </span>negative<span>, and has no sign. Two </span>integers<span> are opposites if they are each the same distance away from zero, but on opposite sides of the number line.
ex. -10+-2 would be a negative integer you just add them and keep the sign
