Answer:
2(28)=23+x
Step-by-step explanation:
There are 28 students and each student needs two brownies. You have to multiply 28 by 2 so you will have to total number on one side.
On the other you need to have the number of brownies you have at the moment and x for the number you need to bake. You want to add them because you will need to put those numbers together to get the number on the opposite side.
28x2=56 so 56=23+x. Subtract the 23 from both sides to get 33=x. x=33
To check plug 33 into x to get 2(28)=23+33. 56=23+33. 56=56
you need 33 more brownies.
So the equation would be 2(28)=23+x.
Hope that helps.
Answer:
36 in
Step-by-step explanation:
The ratio of proportionality between the two similar triangles is 1:6, which you can find by dividing the corresponding side length measures from each triangle (3/18 = 4/24). Then you can set up a proportion:
1/6 = 6/x, which you can solve to get x = 36
It would be the second option n^3 (4n+1)
Fraction left after spending = 1 - 1/3 = 2/3
Fraction saved = 3/8 x 2/3 = 1/4
Fraction left after saving = 2/3 - 1/4 = 5/12
Fraction shared with 3 people = 5/12 ÷ 3 = 5/12 x 1/3 = 5/36
Answer: 5/36
