Answer:
2 packs.
Step-by-step explanation:
Each sticker pack is 21 stickers and you would want to get 50 in total.
Since he already has 8 stickers, the initial value is 8.
So, 50-8 is 42. That means Anthony would need 42 more stickers to reach 50.
At this point, you can do division and that would give you 2.
You can check your work by working backwards and seeing that 2(21)=42.
42+8=50.
First, let's declare some variables.
x = # of sticker packs
y = total # of stickers
Now, let's create an equation to model the problem.
y = 21x + 8
Let's plug in 50 for y and solve for x.
50 = 21x + 8
Subtract 8 from both sides.
42 = 21x
Divide both sides by 21
2 = x
Anthony will have to buy 2 sticker packs to have a total of 50 stickers.
2 : 5
700 g : 1.75 kg
Since ratio should be between same units, so we'll convert either g into kg or kg into g. For convenience, kg will be converted to g
700 g : 1.75 kg × 1000
700 g : 1750 g
÷ 50 ÷50
14 : 35
÷7 ÷7
b
y = x^2 + 12x + 27
or
x^2 + 12x + 27 = 0
(x + 9)(x + 3) = 0
x = -3, -9
36 i guess ha please that not right
