Answer:
Okay, so we know a number of students and the amount of girls as a bracket. So what we have to do now is multiply them with each other.
28 *4/7 = 16
So there are 16 girls in Mr. Chang´s class.
You can also determine the boys by - the students with the girls:
28-16=12 boys
Have a nice day :D

Answer:
x=-3
Step-by-step explanation:
-2x2=-4
-4-16x-44=0
combine like terms (-4,-16)
-48-16x=0
move the 16x to the other side of the equal sign (add 16 since its -)
-48=16x
you need x alone so you need to divide by 16
-3=x
Answer:
Answer: B, 6/11
Step-by-step explanation:
<em>Well we know that 3+2+1=6+3=9.</em>
<em>So that means we will add the 2 brown crayons to the denominator.</em>
<em>The denominator before we added 2 to it, it was 9 as a common denominator. If we want to get the common numerator we are going to have to add the top and that will become 9 then you will have to subtract that by 3</em>
<em>6/11 is also the smallest number that you can get.</em>
<em>You can turn the fraction into a decimal and have it that way to make it easier.</em>
<em>When you turn a fraction into a decimal the number is always the same but with comparing numbers it is a lot easier to do than comparing fractions</em>
Hope this helps, and if it did I would appreciate it if you marked me as Brainllest. Have a wonderful day!
Answer:
B
Step-by-step explanation:
The average rate of change is synonymous with the slope.
So, essentially, we want to find the average slope of our function f(x) from x=0 to x=10.
So, we will use the two following points: (0,5) and (10, -20).
Recall the slope formula:
Let (0, 5) be (x₁, y₁) and (10, -20) be (x₂, y₂). Substitute. This yields:
Subtract and reduce:
So, the average slope of f(x) between x=0 and x=10 is -5/2.
Our answer is B.
And we're done!
Answer:
Its A x - 55 = 39
Step-by-step explanation:
x - 55 = 39
x = 39 + 55
x = 94
This is correct as they sold 39 and kept 55
This means they had 94 to begin with.
I hope this helps ^_^
