I think the ratio is for for every 4 packs it cost 10 dollars so in all it would cost 30 dollars
-4(x + 1) + 7x = 8
-4x - 4 + 7x = 8
3x - 4 = 8
3x = 8 + 4
3x = 12
x = 12/3
x = 4 <===
Answer:
The Cookie Club cookies have less chocolate chips then Wendy does.
Step-by-step explanation:
35/5= 7 100/15= 6 1/3
Your equation for number one is 600,788,188/760,507,625 = x/100
After cross multiplying you will get 760,507,625x = 60,078,818,800
Then you will divide by <span>760,507,625 to isolate the varible to get 78.99 = x.
Your equation in number two is 80/143 = x/100 because when you subtract 143 by 63 you get 80, the amount of males in the room. Then you cross multiply to get, 143x = 8000. Then you would divide both sides by 143 to isolate the varible to get 55%</span>
Given parameters:
Weight of Tan = 146pounds
Unknown:
Weight of Minh = ?
Following this problem step wisely, we can derive a solvable algebraic equation;
Let the weight of Minh = M
In the second sentence, we see that Minh weighs 15pounds more than Tan;
So;
M = 15 + Weight of Tan
Since we already know the weight of Tan,
Weight of Minh = 15 + 146 = 161pounds
We clearly see that Minh's weight will be 161 pounds.
