D. This is the answer because 3 bags with 7 would be 3x7 and your answer would be 21
note: f=fruit
y=yoghurt
2:3
f : y
f/y=2/3
=> 3*f=2*y
f=(2*y)/3
we know that f+y=185g
(2*y)/3+y=185g
(2*y+3*y)/3=185g
5*y/3=185
y=(185*3)/5
y=111g
=>the mass of the yoghurt is 111 g
Answer:
F(-3)=12
F(2)=7
F(0)=3
F(5)=28
Step-by-step explanation:
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
