Answer:

84 students

Step-by-step explanation:

We know that the ratio of boys to girls is 4 : 3, and we know that the actual number of boys is 48, so let's set up a proportion:

\frac{4boys}{3girls} =\frac{48boys}{x girls}, where x is the number of girls in the club

Cross-multiply:

4x = 48 * 3 = 144

x = 144/4 = 36

Thus, there are 36 girls in the club.

Don't forget to check back with the question! It's asking for the total number of students, so we need to add 36 to 48:

36 + 48 = 84

Therefore, our answer is 84 students.

Answer:

  none of the above

Step-by-step explanation:

The problem as written cannot have any of the solutions offered.

For any of those choices, the right side expression will be irrational. The left side expression will be rational for any rational value of x, so cannot be equal to the right-side expression.

The solution is an irrational number near ...

  x ≈ 1.33682898582

Write the 2 digit number that matches the clue
Wittaler [7]
You can figure this out by setting up an equation and make

x= tens digit
y= ones digit

y + 8 =x (tens digit 8 more than ones)

also we know that 

y>0
x>0

since the 10s digit and 1s digit cannot be more than one number, we can say

0 < y > 10
0 < x > 10

since x has to be greater than 0 but less than 10, there is only one number that would fit into the equation for y

2 + 8 = 10
(y cannot equal 2 because than x is equal to 10 and it must be less than)

1 + 8 = 9 
( y can be 1 since x is less than 10)

so it would be 
y= 1
x= 9

the number would be 91

hope this helped!

7r-5r+8=9r+8-r translate to an equation, then solve
pshichka [43]

Answer:

r=0

Step-by-step explanation:

7r-5r+8=9r+8-r

This is already an equation

Combine like terms

2r+8 = 8r+8

Subtract 2r from each side

2r-2r +8 = 8r-2r +8

8 =6r+8

Subtract 8 from each side

8-8 = 6r+8-8

0 = 6r

Divide by 6

0/6 = 6r/6

0 =r
