OK. What are the known facts? We need 20 servings, and 1/3 cup is for 8. Let's move things around. Think as if 1/3 was for 5 people. That would mean you would need 1 1/3 cups for 20 servings. Because 5*4 is 20 and 1/3*4 is 1 1/3. Now for the extra 3. There are 4 sets of 3 total left, which is 12. 12 is 1 1/2 of 8, so we need 1/3 cup and half of 1/3. I don't want to give the entire thing away, so I will leave that for you to figure out! Bye :D
Y = x - 1
and uh uh there aren’t any extra points but cool
You're using inverse operation to solve this equation. Now you just have to think about it. What number plus 20 would equal the same number squared? The answer would be 5, since
5+20=5^2
25=25
The statement above is true :)
Another number that would work for the equation would be x= -4
-4+20=-4^2
16=16
The statement above is also true so your answer would be x=-4 and 5
Answer:
The cross multiplication would be 10(350) = 22(x).
Step-by-step explanation:
We would first convert meters to centimeters. There are 100 cm in a meter; this means 3.5 m = 3.5(100) = 350 cm.
The ratio of the height to base of the model is 10/22. The ratio of the playhouse would then be x/350. This gives us
10/22 = x/350
Cross multiplying, we would have 10(350) = 22(x).
