For every girl taking classes at school there are three boys if there are 236 student how many are boys.
BaLLatris [955]
1:3 is the ratio to boys and girls. I know that 1/4 must be girls. 3/4 will be boys.

Divide 236 by 4.

236/4= 59

Multiply that by 3.

59*3= 177

177 of the students are boys.

I hope this helps!

Which values, when placed in the box, would result in a system of equations with no solution? Check all that apply.
son4ous [18]

For this case we have the following system of equations:

y = -2x + 4\\6x + 3y =

Rewriting equation 1 we have:

2x + y = 4

Therefore, the equivalent system is:

2x + y = 4\\6x + 3y =

The system will have no solution, if we write equation 2 as a linear combination of equation 1.

Therefore, since both lines have the same slope, they are parallel.

Parallel lines do not intersect when they have different cut points.

Therefore, there is no solution for:

-12, -4, 0, 4

The system has inifinites solutions for:

12

This is because the lines intersect at all points in the domain.

Answer:

The values, when placed in the box, would result in a system of equations with no solution are:

A: -12

B: -4

C: 0

D: 4

The sum of three numbers is 117 . the third number is 3 times the second. the first number is 8 less than the second. what are t
tamaranim1 [39]
Let the second number be x.

First number = x - 8

Third number = 3x

Sum of the numbers = 117

x - 8 + x + 3x = 117

5x = 125

x = 25

Thus,

The first number is 17. The second number is 25. The third number is 75.
