There is a percent formula that can solve all of these...
is / of = % / 100
what percent is 32 out of 80...
% = x...because this is what we r looking for
is = 32
of = 80
now sub into the formula
32/80 = x/100
cross multiply because this is a proportion
(80)(x) = (32)(100)
80x = 3200
x = 3200/80
x = 40......so 32 is 40% of 80
12 is 60% of what number...
is = 12
% = 60
of = x
sub
12/x = 60/100
cross multiply
(60)(x) = (12)(100)
60x = 1200
x = 1200/60
x = 20.....so 12 is 60% of 20
what is 30% of 70
is = x
% = 30
of = 70
x / 70 = 30/100
(100)(x) = (30)(70)
100x = 2100
x = 2100/100
x = 21.....so 21 is 30% of 70
what is 40% of 75
is = x
% = 40
of = 75
x / 75 = 40/100
(100)(x) = (75)(40)
100x = 3000
x = 3000/100
x = 30....so 30 is 40% of 75
the pic
what is 40% of 35
is = x
% = 40
of = 35
x/35 = 40/100
(100)(x) = (35)(40)
100x = 1400
x = 1400/100
x = 14.....so 14 is 40% of 35....14 goes in the box
Answer: x2+17x+3
Step-by-step explanation:
2x2+7x−x2+10x+3
=2x2+7x+−x2+10x+3
Combine Like Terms:
=2x2+7x+−x2+10x+3
=(2x2+−x2)+(7x+10x)+(3)
=x2+17x+3
