the numbers are x and x-1
a.
"product of them is equal to 35 more than 11 times sum of them" translated to maths is
(x)(x-1)=35+11(x+x-1)
we need to get it into standard form (
)
expand
b.
factor
what 2 numbers multiply to get -24 and add to get -23?
-24 and 1
set each equal to 0
x-24=0, x=24
x+1=0, x=-1
the solutions are 24 and -1
c.
if x=24, then x-1=23, the 2 numbers are 24 and 23
if x=-1, then x-1=-2, the 2 numbers are -1 and -2
since the question did not specify if the numbers had to be of a certain sign (positive or negative) or something like that, there are 2 pairs of consecutive numbers that satisfy the equation
"seven" means ' 7 '
"two" means ' 2 '
"the quantity seven plus two" means ' (7 + 2) '
"one hundred times the quantity ..." means ' <em>100 (7 + 2)</em> '
That's the expression.
One of the rules for handling these things is that you should always
take care of anything inside parentheses first. So do that.
(7 + 2) = 9
Now you can can write the expression like this: ' 100 (9) ' .
That's just <em>900 .
