2|x+5.3| = 4.2 is equivalent to

(1) 2(x+5.3) = 4.2 when x+5.3 >= 0
solve x = -3.2 when x >= -5.3 ... good value
('good value' means the value has no conflict with the condition -- when)

and

(2) 2[-(x+5.3)] = 4.2 when x+5.3 < 0
solve x = -7.4 when x < -5.3 ... also good

x = -3.2 or -7.4

The ratio of boys to girls in the gym was 4 to 5. How many boys were in the gym if there were 125 girls in the gym?
Anna007 [38]

Answer:

If there are 125 girls, and the ratio is boys to girls, then you can divide 125 by 5 to get the multiplication factor. This would be 25. Now you can multiply 25 by 4 to get how many boys were in the gym, which would be 100. To get back to your original ratio, you can divide 100/125 by 25 on top and bottom to get 4:5, or 4/5. :)

Sarah is solving the equation -7/8x=24
ExtremeBDS [4]

the answer would be -21 because you would have to multiply the 24 by -7 because it is dividing on the other side. and then you would have to divide the number you get by 8

so basically, it will look like this step by step:

-7/8x=24

8x=24*-7

8x=-168

x=-168/8

x= -21
