Answer:
There are 25 students in the class.
Step-by-step explanation:
Since we know the percentage of students who want an ice cream party is 20%, and 5 students want an ice cream party, we know that:

, where S is the total amount of students. We can then solve for S:
Given equation
Multiply by S
Divide by 0.2
Therefore, there are 25 students in the class.
Answer:
18 x 348 = 6,264.
Sofia's grandfather has 6,264 candies in total.
Answer:
See below.
Step-by-step explanation:
So we started off with the equation:

And we subtracted x from both sides to acquire:

Now, this is essentially slope-intercept form. Recall that the slope-intercept form is:

Where m is the slope and b is the y-intercept.
If we rearrange our equation:

And put some parentheses:

We can see that this is indeed slope-intercept form.
And we can see that m is -1 and b is 2.
In other words, the slope is -1 and the y-intercept is 2.
Answer:

Step-by-step explanation:
If you write it out it will look like this 8 1/2÷1 7/10
since you can't divide mixed fractions very easily, you make them improper fractions. 8 1/2 -> 17/2 1 7/10 -> 17/10
So it looks like 17/2÷17/10
because of maths you have to turn 17/10 into 10/17
And when you do the maths (multiply it together) you get 5
