So you're initial equation is
. Well since
, plug in 24 for the 1 in
. So
, and
so
.
AA = $1
AAA= $0.75
AA + AAA = 42
$1AA + $0.75AAA= $37
AA + AAA = 42
AA + AAA-AAA= 42- AAA
AA = 42- AAA
$1(42- AAA) + $0.75AAA= $37
$42 - AAA +0.75AAA = $37
$42 -0.25AAA= $37
$42-$42 -0.25AAA= $37 -$42
-0.25AAA= -5
-0.25AAA/-0.25 = -5/-0.25
AAA= 20
AA + AAA= 42
AA + 20 = 42
AA +20 -20 = 42-20
AA= 22
Check
$1AA + $0.75AAA= $37
$1(22)+ $0.75(20)= $37
$22 + $15 =$37
$37 = $37
Twice means times 2.
1) 2(ab) gives twice the product of a and b.
2) (2a)b gives the product of twice a and b.
Answer:
Work shown below!
Step-by-step explanation:
(x + 4)(x - 3) = 
'is' means equals
'of' means mutily so
we have
18 =0.4 times what
divide both sides by 0.4
45=what
the answer is the number is 45
