You’re so smart, I love questions like this. Hopefully you can solve it so I can know too!
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:
16.5mm to. 1 decimal place
Step-by-step explanation:
Please check attachment for diagrammatic representation of the triangle.
Since one of the angles of the triangle is 90, this means that we are dealing with a right angled triangle
To find the length of AC, we make use of pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the square of the other two sides. The hypotenuse is the longest side of the triangle which we have as 17.88 mm
Mathematically therefore
17.8^2 = 6.6^2 + AC^2
AC^2 = 17.8^2 - 6.6^2
AC^2 = 283.28
AC = √(273.28)
AC = 16.53 mm
This is 16.5 to 1 decimal place
Get a common denominator.
3/10 = 30/100
30/100 + 3/100 = 33/100
Answer: 33/100
